Dumb DOMS

This post was originally published in The Run Experience in a slightly different version.

Today I’m feeling sore. I was fine yesterday, exercised and then I woke up this morning feeling old and grumpy. Dumb DOMS: Delayed Onset Muscle Soreness.

So what is DOMS? There are many theories but nobody knows for sure how it happens. It’s biology so it is probably a mix of things. Among the popular explanations are : connective tissue damage, muscle damage, accumulation of calcium inside the muscle and in between fibers and inflammation. It mostly happens doing eccentric exercises. Basically anytime you lower a weight in a controlled fashion or when running downhill in a races.

What can be done?

In theory DOMS is a minor injury, so RICE (Rest, Ice, Compression, Elevation) should apply here. Rest: It will go away in a couple of days. However you can still exercise and the pain will disappear temporarily but come back shortly after. Ice: The idea is to reduce inflammation and it has definitely mixed results in the literature. It could also blunt the training adaptation, more on this below. I don’t know about you but ice is torture to me. Compression and Elevation: From what I’ve seen it has some potential, and I’ve tried it myself. I love the 2XU pants and I’ll wear them at work sometimes under everything. It removes some of the pain and makes my legs feel lighter.

Nothing works for me better than a hot bath with magnesium salts. And from the literature, it looks like two days before an event would also benefit recovery after. Last but not least: massage. Ouch! My husband always think that I’m having a leisurely relaxing one hour massage. Let me tell you the truth. It hurts like hell and is even more painful than the training. I usually do not like to get a massage when I have DOMS, same reason as ice bath, why create more pain? But after a couple of days, it is always a good idea to remove the remaining knots in your muscle.

What about nutrition?

A lot can be done there too. The key answer: proteins and carbohydrates together. That is how the Got Chocolate Milk campaign was born. It is a bit of a big FAT scam or I should say a big SUGAR scam since most of these studies supporting milk chocolate for recovery were founded by the milk industry…

Don't get me wrong, I love Mirinda. (Go get them Mirinda!)
Don’t get me wrong, I love Mirinda. (Go get them Mirinda!)

They are not wrong but try this option with less sugar: blend together milk, whey or plant protein (half a scoop to 1 scoop), a banana and some cocoa powder (of good quality)! Tip: You can add whey or plant protein to your milk to make it higher in protein content, about half a scoop!)

13304754284_3d09fd3089_k

Milk has the advantage of having the electrolytes compared to the whey. None of the sugar and same effect. Plus the chocolate powder might have some good recovery properties because it contains quercetin a potent antioxidant and anti-inflammatory.

But beware, more on this below.

After a hard session, papers report that in general 0.8g/kg of carbs + 0.4g/kg of whey protein works magic or 2:1 ratio carbs to protein to replenish your glycogen stores and keep protein synthesis up and running. That is between 20 and 35g of protein depending on your weight.

Above that amount there is probably no significant impact.

Ideally you’ll want to have this in a meal with real food within 2 hours of your session, but if you can’t, try a protein bar as a snack. (ProBar or Quest as examples) but there are many on the market.

Protein and carbs together work synergistically, as both will increase insulin and promote cellular uptake of nutrients for repair. Instead of whey you can use casein before bed time as it will release more slowly overnight.

Other supplements?

Anti-oxidants of course: Vitamin C, E and NAC (N-acetyl-cysteine) are among the most popular anti-oxidants out there. They scavenge free radical (ROS) and help you recover faster. However research is showing that ROS are actually needed for signaling training adaptation. You could totally blunt that response by using too much of them. So use if needed only when no training adaptation is required perhaps during a taper, recovery or the week after a race.

Anti-inflammatory compound are also very useful. Of course, there is the popular over the counter anti-inflammatory Ibuprofen, part of the NSAID category. If I can not sleep,  I will go for it since sleep is one of the most proven way to recover.

But do not abuse.

It has a negative effect on muscle growth and therefore could undermine all your efforts a little bit like too much anti-oxidants. Plus it can give you gastrointestinal issues and other nasty side effects.

A more natural compound would be curcumin or turmeric. It has a similar mechanism of action than NSAID but does not cause thinning of the stomach lining. A recent study has shown that ingesting 2.5g of curmumin twice a day a couple of days before and after the exercise bout could be beneficial. But could it impair training adaptation? I don’t think this has been studied yet but since it acts similarly as NSAID I would not be surprised if it did.

Finally, tart cherry juice has also been studied a lot and here is a good paper. Like many fruit and vegetables, tart cherries contains a lot of anti-oxidants and flavonoids which have anti-inflammatory properties. Using around a marathon would not be a bad idea but during training could potentially inhibits training adaptation. We don’t know yet. Be careful with this one though. Tart cherry juice consumed in the quantities that are suggested contains a lot of xylitol a sugar alcohol that can ferment and give you the runs so definitely test beforehand.

Feeling adventurous?

Have you heard of HMB?  It is a derivative of leucine, one of the most potent amino acid in terms of muscle growth. It has been reported that HMB (Beta-Hydroxy-MethylButyrate free salt) can help alleviate symptoms of DOMS but results are still mitigated. HMB is however safe and worth trying if you know that you will have multiple hard work-outs during the week. It works at reducing protein degradation. A dose of 3 g before exercising would be recommended in that instance.

Then in the same line of thought, amino acids and BCAA, which stands for branched chained amino acid (leucine is one of them) have also shown to reduce DOMS in some instance. Doses vary from 5 to 12g, once or twice per day, 7-10 days before. But since most proteins (in particular whey and casein) contains those, you probably have your grounds covered already.

And then you have Citrulline-malate which at 8g could alleviate DOMS and also L-carnitine, which has to be loaded with 3g/day for 3 weeks for an effect on reducing muscle damage. The good thing about that one is that it also can increase fat metabolism and make you a better fat burner at the same time. Who does not like that?

Beware though, a lot of these studies use muscle damage as a marker which is most likely correlated with muscle soreness but not always and is individual. So see if it works for you.

No Pain No Gain?

Unfortunately, it might be a little bit true.. So my advice go slow and build up, and try some of the strategies listed here. Be aware that some of them could impair training adaptations, so time them carefully.

Hi! This is a long post and  I apologize. If you are only interested in the nutrition you can skip my jabbering and go directly to the relevant paragraphs. That is fine with me!

When I started triathlon 10 years ago, I never wanted, never thought I would do an Ironman. Its too crazy, too much, too hard, not good for your health. So then why did I decide to do one? Just that: it’s been 10 years and I had to try one, no choice. Plus my kids were getting bigger and I had quit my job, so no more excuses. Because let’s not underestimate this Ironman, it is a lot of training!

The Training:

In order to be successful I hired a coach, JD. It was so valuable I cannot say the least. He really kept me healthy during the whole process. The training was hard for sure. I had to remember to eat well (of course) and sleep a lot (more challenging).

The bicycling part was the most difficult for me as it takes the longest.  So far in my life,  I had done lots of 60-70 miles bike rides and also lots of bicycling tours but never above the 80 miles mark in one day.  I had a lot of work to do, or so I thought. But JD had me do only four rides that were 80, 90, 100 and 90 miles.  That’s it.

The running came in a little bit more easily because I’ve always been a runner first.  However the longest run I did was only 19 miles with lots of hills which would prove to be much more difficult than the flattish marathon at the end of the IM.

Swimming felt fine, as I had done over the distance several times.

Even with all that, I was not feeling too confident that I would be successful because how can you run a marathon after 112 miles of cycling and 3800 yards of swimming?  However I trusted my coach as he said I was ready so I tried not to worry too much.

The Tapering:

The Ironman was up in Whistler and we decided to drive there in 2 days. I actually thought that driving was a great idea especially if you have someone driving for you. What better than doing nothing for 8 hours with feet elevated on the dashboard. I had been feeling pretty tired but after that drive up and minimal training apart for the treadmill in the hotel gym, I was starting to feel back in the groove of things.

As soon as we got there we went for a swim to Alta lake, where it was going to start. The lake was beautiful and the temperature was perfect (70F). I had brought a sleeveless wetsuit just in case but I did not think I would need it at that point because the weather forecast said it was going to rain. The swim in the lake was great and freshwater is always so nice to swim in, except for the leeches…My husband told me that the swimmer that had gotten out just before me had one stuck to his leg. Nice. And then my son tells me: Mom you have a leech on your ankle! I jumped and looked down, it was only a leaf. Gosh. What can you do if you have a leech stuck to you during the race? That’s enough to drain your blood by the end of it.. I did try not to think about it, anyway it’s always better than being bitten by a shark.

The next day I went for a short bike ride. By then my legs were really feeling fresh! What a difference as I had been training on tired legs a lot.  The road were also wide and well paved. I was finally getting excited.

On the Saturday I did a quick swim and run and started preparing all my transition, special needs bags and nutrition needs. Wow, it’s like planning a wedding. I had a list of all the things to do, where to put them. Then I had to go drop my bicycle at the lake via the shuttles with all my bags except for the nutrition.  I was getting a little nervous then. Fortunately I saw my friend Erika in the shuttle bus so that gave me a break from my thinking brain. I spent the rest of the afternoon prepping nutrition and relaxing. We went out for a good dinner. I did not stuff myself, had chicken veggies and potatoes, very safe. Oh and some dessert too that we shared amongst everybody. And a non-alcoholic beer, because I like the taste.

Race Day!

I had set my alarm at 4:00AM, was planning to get on the first bus at 5AM ish. The start was at 7AM but I preferred that since I did not know what to expect. Of course I was awake by 3:00 and could not sleep anymore. Been there, done that so I know that one night of bad sleep would not impact me that much. I got up and made a super strong Bulletproof coffee. I don’t drink coffee regularly so when I drink one, it’s party time. Just that was making my day already (see earlier post). For those of you who don’t know what a bulletproof coffee is, it is coffee with butter and MCT oil (medium chain triglyceride), it is a type of fat that gets readily absorbed and metabolized pretty quickly, and in your brain too. It is derived from coconut oil. With that on board I started to get ready, I also prepared my pre-race smoothie which I would start drinking an hour before the race start. It contained some almond milk, cliff organic food pouch: banana, mango and coconut, some peanut butter, 2 scoops of plain UCAN superstarch and a little whey protein and that is about it!  Nothing to weighty.

The Swim!

One of the thing I felt ready for was the swim. But I forgot about the MASS START. The coach told me don’t go in the middle and of course this is where I was. I thought I was in the front, but no. I could see Erika, she was right there at the front, she is a fast swimmer and I thought I should be fine where I was. NOT. It was terrible. I could not swim freely for the whole first lap and I had to constantly find holes and ways to not get kicked. It is only after the first lap that I started feeling that I had more space. But even though just to be safe I stayed pretty far from the buoy. As a result my total distance was 4600 yard and normally it is 3800 yards. Rookie mistake number 1! I don’t know how accurate these Garmins are. My watch said that my pace was 1:34, which would have been a little fast. But overall it took me 1:12, I was a bit bummed but the swim is such a small portion that I did not let it get to me too much.

By the time I was out of the water, it was raining hard! I went to get my bag and then remembered about the wet suit strippers. Where were they? Found them got that taken care of and went in the changing tent. That is one nice thing I must say about Ironman, is the changing tent with all the volunteers that help you get dressed. I had decided to change completely and since it was raining I was hesitating on what to wear: wind breaker or no windbreaker: no windbreaker because I was feeling warm (bad decision). Fortunately I stashed it in my pocket just in case. 12 minutes transition! mmm, need to work on that one. Rookie mistake # 2

The Bike!

It was raining hard on the bike. I thought, it is going to be a long day of wetness, first moment of darkness but swooshed that thought away. I was hoping that the forecast was going to clear a little bit later like the weather forecast was saying. On the first 10 miles, I got cold very quickly and was shivering. I hope I don’t get hypothermia, I thought. Pedal faster to warm-up, I said to myself. And so I did, but it did not work that well. Remember that wind breaker? That is when I stopped and put it on. Even though I was all wet under, it still warmed me up. I could see the pros coming back from the first turn around on the other side and some of them were actually quitting already because of the bad weather…Well that does not look good. However I managed to warm up. The only thing is that my wind breaker is not really aerodynamic and was acting more like a parachute. Not good. Rookie mistake # 3.

When I got to the special needs I was happy to have dry socks there. I finally removed my windbreaker because the temperature was raising and it was no longer raining. Then the boring part started: dead flat for 30 miles. Ugh. That was hard for me. I don’t have a TimeTrial bike and my position is not optimal and it was not comfortable. Which made me thought that after this I need to get a real Time Trial bike or quit triathlon because this sucks. That was my dark moment number 2 but I managed to pushed it away and focused in the moment. That meant thinking that I had to go pee badly and was not going to pee on the bike. Really people? Who does that? Mind you I was already wet.  The sad part is that at every aid station there was a long line at the porta-potty. Fortunately I eventually found one which was at the other side of the road and was free!

Then I saw Claire and Erika coming back on the other side and that motivated me to keep the pace. Finally we got to the hills. Yeah! You must think I’m crazy but I was so happy to get out of aero position just sit really straight and push up and up. I was feeling really good at that point, knowing that the bike was going to end soon and that after an uphill, there is a downhill. My legs were getting tired but not too bad. Seven hours and I was done, better than anticipated with those hills!

Me and my parachute.
Me and my parachute.

Bike Nutrition

At least I got the nutrition right!

I got my first dose of UCAN approximately 1:45 hours into the race. I had in it some MCT oil (2tsp) and BCAA (3g) to complement and I would have that every 1:45 or so. I also was eating quarters of BonkBreakers every half hours if no UCAN and alternating with some peanut butter and honey. I really felt good with even energy.

The Run!

I was really happy to finish the bike and get into the run. Was trying not to think that I had to run a marathon until Claire reminded me as we were finishing the bike together (thanks Claire, shut up Claire, you are still my friend though!)

Again, I got in the changing tent for a complete wardrobe turnover! Applied bunch of anti-chaffing everywhere and was ready to go. The volunteer was so encouraging and she told me she was going to be at the finish to tell everybody it was my first one. How nice!

I started running with Claire and saw my family on the side cheering me on. So nice to see them. In my head I did the calculation: 20 aid stations divided by 4 equals 5. I can still do math! OK, let’s focus on the first 5 ones, first one quarter. I would run like that pretty much the whole time: run to #1 as fast as you can, walk, have a sip, eat maybe and then repeat and start over for the next 4. That got me busy. Walking at each aid station also breaks it up and helped avoiding cramping and injury and really it does not change your time that much if you walk for 10 seconds. My pace was pretty even for the whole race but did slow down a little bit as time went on. Oh and no I did not see any bears. 4:26 marathon, pretty far from an open one but I’ll take it!

Going on the run

Run Nutrition

About 30 minutes in I had a dose of UCAN again, with some EAA in it that is it. I also sipped on a Peanut Butter GU gel for an hour . No too much fat not to upset my stomach and anyway I did not feel hungry at all at that point and had good energy. Of course my legs were tired but I guess it is normal. I was only drinking water to thirst at aid station and having salt pills for what it is worth, research is not clear on this one yet! At the special needs I was feeling really thirsty fortunately I had put a Perrier can in my bag and gulped half of it which totally quenched my thirst. I don’t know what it is,  but the combination of bubbles and slight sodium is just wonderful.  At that point I was suppose to take another dose of UCAN but instead I opted to start coking it up. I never drink Coke but this is when I do it because there is always a place for sugar and caffeine! I also started having broth as it was getting cold when it started pouring again.

The Finish!

Hurray, the finish line! I was getting so pumped up and started picking up the pace, I still had it in me. But the villain course designer had us do a zig and a zag in the village before heading to the finish. When is that going to end? Nevertheless, I was so happy and smiling at everyone. I saw my family at the end and high fived everybody at the finish line. This is as close as I’m going to feel like a super star, red carpet and all but definitely not looking too glamorous.

High-Five!
High-Five!

Nutrition Summary

3x27g UCAN orange flavor: 330 kcal,  81g of carbs

1×1.5 scoop plain UCAN: 135 kcal, 33g of carbs

4 tsp BCAA, 2.5 g/tsp

6 tsp MCT oil: 200 kcal

4 Tsp peanut butter: 400 kcal, 28g of carbs

8 tsp honey: 160 kcal, 40 g carbs

1.75 Bonk Breakers: 473 kcal, 58g of carbs

1 GU gel: 90 kcal, 22g of carbs.

app 0.75 can, not too sure about that one: 120 kcal, 30g of carbs

also some salt pills and caffeine pills.

Total: 1908  kcal, 145 kcal/hour and 292g/carbs and 22 g/hour. This is actually pretty good for me and even on the high side as at those pace I am more of a fat burner but since it was my first IM and I did not experience any GI issues at all, why not?

According to my Training Peak files and Metabolic Efficiency data, this is what I burned during the race: 287g of carbs during the bike, 150 g of carbs during the run and let’s say 30g during the swim. 467 g total. Bout 70% comes from glycogen reserve or the equivalent of 300 g. That is pretty close to what I would have stored in my legs. Of course, this is just an approximation and it is important to remember as the duration increases your body start burning more fat, so I probably burned less than that. I still have a lot of work to do if I want to go faster. But what counts at the end is that:

I am an IronWOman!

Finish!
Finish!

I really want to thank everybody who supported me. My husband, my children, my coach(es) and all my friends. I was really touched and surprised by all the support I got on in the form of messages and phone calls. Thank you!

In the Swing of Carbohydrates Part 2


2 Comments

In part 1, I discussed on how a low-carbohydrate diet seems to be healthier. But remember that there are no real definition of what is a low carbohydrate diet. For me,  based on the research paper that I’ve read, RDA levels and our paleo ancestors, I would put the threshold  below 35% or for a 2000 kcal diet, that is about 175g of carbs per day. To be honest I’m not even there and my diet usually fluctuates between 80g and 160g. The majority of my carbohydrate intake comes from fruits (2 servings per day) and dairy, while potatoes and rice and whole grains, I eat more rarely, mostly when my training is either high intensity or longer. Oh, and I forgot to mention wine and dark chocolate…Am I suppose to tell you that?

But what about performance? We all know that carbs are necessary to perform well, especially at high intensity. Carbohydrates in the form of glycogen is our reserve for when the lion attacks and we need to run fast! So when we are out of glycogen and our blood sugar drops, we fatigue. Carbohydrate are so wonderful that when we swish a carbohydrate solution in our mouth, it has been shown to improve performance, even for 1 hour events when carbohydrates are not really needed. On the other end, other studies have also shown that training with low glycogen or carbohydrates on board activates mitochondrial gene expression, which in turns will improve training adaptation.

Recommendations for performance

Currently the recommendations for optimal performance stands at 8-10g/kg daily of carbohydrates. If you do the math, taking me as an example, that would be 560g or 2240 kcal of carbs. Basically on a day where I exercise for 1.5 hour at moderate intensity that is my whole calorie intake for the day! Ten bagels, here you go. OK, I’m being a little bit facetious but if you look deeper into the litterature, these recommendations are  for athletes who actually spend a lot more energy per day such as Tour de France cyclist or someone who exercises 5+ hours per day. I would probably fall in the 6 g/kg/day or  350g carbohydrate per day with my 1.5 hour of exercise. That is still a lot and I consume less as mentioned earlier. These recommendations stems from research that is not wrong in essence but we need to look at how it is done. First of all these studies are done with athletes that use carbs as their main fuel, they are not adapted to a lower carb, higher fat diet and if they are, it is not for a long time. Even if you adapt for 5-6 days you don’t get the full benefits of athletes who have been going at it for a long time, as you will see below. So basically what the researchers do is that they take an athlete, have them exercise for however long and then measure glycogen after the exercise bout. Then they look at how much carbohydrates are needed to reestablished normal levels. The thing is if you don’t use as much glycogen because your metabolism oxidizes a lot of fat instead of carbs then you’ll need less to reestablish current levels. Does that make sense? In essence they are not wrong, you will need that amount of carbs if you are a high carb burner, but if you burn more fat probably not.

Actually the research is starting to take off in the low carb high fat department. Let’s look at the preliminary results of the FASTER study. They looked at two different elite athlete cohorts participating in ultra-marathons. One was on a high carb diet (60%) and the other one was at 10-12% in carbohydrate. If you look at the difference in fat oxidation between the two cohorts, it is huge! The HFD oxidized 50% more fat than the high carb. How long did it take them to get there? You have to have mitochondrial adaptation, higher intramuscular triglyceride (fat) storage, changes that do not happen overnight even if your fat oxidation per se can increase very quickly because of a change in your diet.

fat_adaptation-5-240x180

Now let’s look at what are the requirements during races. It is on average 1g/min of carbohydrate or 40-60g/hour. It is not reported per kg because the limiting factor is our gut, above that level carbs do not get absorbed very well. However, you can train your gut to absorb more carbohydrates to a certain extent. This is definitely too high for me and on average during triathlon and other events I’ll have about 20g/hour of carbohydrate with some proteins and fats for longer events.

And then for recovery the suggestion is 0.8 to 1.2 g/kg with some proteins, the sooner the better, within 30 min. to 2 hours.  Again this seems a lot to me for a 90 minute session of exercise. But as sessions get longer and harder this is not a bad place to be if you can add at least the same amount of protein in there.

And how am I doing?
 

And now that I’ve shared with you how I use carbohydrates compared to the requirements, how is my performance in all of this?

Since using this strategy, my times have been improving. Last year I had a 20 minute PR at the half-Ironman race and another PR at an Olympic triathlon. I just felt great the whole time in both races, very even energy. I also don’t bonk during long training rides anymore and do not feel nauseated on the run. And I don’t need to eat as much! It is not that I perform necessarily better, I don’t think I would score better on a TT on the bike or a 10K,  but for longer events I can perform to my optimum the whole time, that is what makes the difference. Here is a breakdown of my calorie intake.

For the Half-Ironman:

On the bike every 30 minutes: 1/4 of Bonk Breaker protein
at 1.5 hours on bike: 2 scoops of UCAN*, sipped for 20 minutes
at 2 hours on bike: 1 shot of espresso, 80 mg caffeine
at the beginning of run: 2 scoops of UCAN
1 hour into run: 1 shot of espresso with caffeine (See my blog on caffeine!)

*If you are not familiar with UCAN, it is this slow release corn starch that enables to maintain steady blood sugar.

Total calories: 630=114 kcal/hr
Total carbs: 121g carbs=22g/hour

For my last Olympic, I just had a packet of UCAN for the whole time, and that is it simple: 132 kcal, and 13g/carb per hour. Of course in all those strategies I make sure that my reserves of glycogen are full by having appropriate meals the day before and a breakfast or snack before the race. Again I’ll use UCAN in a shake with 5g protein and some fats an hour before the race starts. In comparison I used to have 30g/hour of maltodextrin and other sugars and would totally bonk on the run. Maybe if I could have ingested more carbs I would have done better but I just could not stomach it.

So what is the difference between now and then is that I am now more metabolically efficient! Of course I did not go at it by myself and got the help of Dina at eNRG Performance. In my next blog, I will talk about testings you can do to know how metabolically efficient you are.

Talk to you soon!

Trail Sushi


2 Comments
I’m on my way to Ironman soon, and my training is definitely ramping up. While Bonkbreakers with protein have been one of my favorite staples as it is available during Ironman races, I am just getting tired of them.  So I’ve been looking around for some homemade alternatives. A while ago,  I found this book called the Feed Zone Portables, it contains recipes for excellent hand size snacks that you can put in your pocket for the long ride or run. Even though they taste good, I find that these portables are in general too big and too dense in carbohydrates. I really don’t want to spike my blood sugar because I don’t want to blunt fat burning during long outings. Also most of them need to be wrapped and that provides a challenge during the ride as I’m not very good at letting go of my handlebars… So what would be a  small portable yummy snack that has just the right amount of carbohydrates, protein and fats? I came up with the Trail Sushi.
Here is the recipe for one whole roll (8 servings):
1 bamboo mat (to roll the sushi)
1 nori sheet (I like this one)
1/4 cup uncooked sushi rice (I like this one)
10 g of vanilla whey protein (I like this one)
2 tsp of grass-fed gelatin (I like this one)
4 tbsp of full fat coconut milk (I like this one)
2 tbsp almond butter
2 tsp honey
First cook the rice in a rice cooker or as directed on the package. Cooking 1/4 cup of rice is not always optimal so you might want to cook more in one time for making multiple rolls. Once cooked, wait until it cools down a bit and then spread it on your nori sheet like this. It is OK if it does not cover everything.

Mix 2 tbsp of coconut milk with the almond butter, honey and whey protein in a small bowl.
Mix the other 2 tbsp of coconut milk with the gelatin in a bowl and heat it up in the microwave until it gets hot, not necessarily boiling. That should take less than 30 sec. depending on your microwave. Once heated, stir the mixture until the gelatin is dissolved.
Mix the gelatin mixture with the almond butter mixture quickly to make a paste. Then you want to spread this mixture over half the rice in a layer, but don’t wait too long as it tends to thicken as it cools down. Now you are ready to roll your sushi.  Once the roll is done,  put it in the fridge for an hour before cutting it into 8 pieces. Always cut starting in the middle, it is easier. There you go!

For each piece of an 8 servings roll, you have 72 kcal with 7g of carbohydrate, mostly high glycemic rice starch with a bit of fructose to maximize carbohydrate absorption, 3 g of protein comprising lots of good amino acids to stave off fatigue and prevent muscle breakdown and 4 g of good fats as an excellent energy source when the ride/run is looong. Also you have the benefit of the nori sheet which contains iodine, good for thyroid function and the gelatin which keeps your joints healthy!
I hope you like it!

Two years ago, I went to the doctor to get the results from a blood test called the HbA1c. It is a test that measures the amount of sugar on your hemoglobin (on your red blood cells) and apparently correlates very well to your average blood sugar over the past 3 months. Then, just out of the blue the doctor tells me: you are pre-diabetic. It seemed surreal. Me? I exercise a lot, healthy eating, no weight to lose (maybe a couple of pounds, but there will always be a couple of pounds). My HbA1C, was at 5.9, pre-diabetes starts at 5.7 and diabetics at 6.4.
First of all diabetes means that your blood sugar levels are higher than average. There are two types. Type 1 is when your pancreas does not produce enough insulin due to genetic defect or other causes. Insulin is a hormone which acts on cells to absorb glucose, in particular muscle cells and liver cells where glucose is synthesized into glycogen (a long sugar chain, similar to starch) or fat cells where it is converted to you guessed it: fat. Insulin has also multiple other roles, which I won’t cover in here. Is insulin really bad for you? Not really, it is not the insulin the problem, it is the overload of sugar. High sugar, the body secretes insulin, cells absorb, absorb and sometimes a bit too much which results in hypoglycemia. Now you are feeling weird, hungry, dizzy and well, reach for another snack which increases your blood sugar again. Welcome to the sugar roller coaster. If you are pre-diabetic or Type II diabetic, this roller coaster is like the Matterhorn. Your insulin does not control very well the process, just like a poorly tuned thermostat which never reaches a set-point but goes way up in temperature and way down before it kicks in again. Some people might be better at regulating this whole process depending on your genes and lifestyle.
Here is a graph that I found at Suppversity. It helps explain where we, humans are coming from compared to where we are at now. It shows the average percentage of carbohydrates in the diet (minimum and maximum) compared to the latitude our paleolithic ancestors were living at.
As you can see some of our ancestors living in the North did not have any carbohydrates during the cold months of the year. While people living in warmer climate had up to 34% of carbohydrates in good times. What is the RDA recommendation these days: 45-65%! And some of us eat up to up to 70% of their diet in carbs. That is a lot compared to what we were technically supposed to handle. No wonder our thermostat is out of whack. Of course if you are very active, you can probably handle more without significant effect, but when I say very active, I mean it. Our ancestors where already pretty active so if you think that you move more than a hunter gatherer, well go ahead.
So what should we do? Low-carb, Ketosis diet, Paleo diet or a mix of these? These are the new cool diets out there. You don’t know what these are? To tell you the truth, I would ask different specialists, I would get different answers but bottom line, the idea behind these is to get closer to what our body is able to handle without negative effect on our health. I would define low-carb diet as having less than 35% of your calories from carbohydrates. From a 2000 calorie diet that is less than 175 g or the equivalent of 5 apples. The ketosis diet is when you go below 50g, at that point your body starts making ketone bodies for your brain because of the lack of sugar, but don’t worry it is not dangerous and can be actually beneficial. The paleo diet uses only ingredients that could be found from hunting and gathering. This diet can be higher in carbs but because of the restrictive carb choices, it tends to be around 35% too.  There is a super interesting article in the National Geographic on paleolithic diets. It turns out that eating paleo is not just about eating more meat. In fact our ancestors did not have access to meat half of the time. I think this is important to point out as some people take the paleolithic diet to extreme and eat too much meat. Although as you will see below, meat and saturated fat in meats are not as evil as we thought. However, other sources of protein should be considered such as in fish, seafood and plant protein and present a much sustainable way of living for the future generation. So what else did our paleo ancestors eat? They had to rely on plants, tubers and nuts found in nature. And yes, these are carbs, but they are non-processed and it turns out that carbs’ density (g of carb/g of total food) is actually low. So on some days they might have eaten a lot of carbs, other days mostly meat and the rest of the time mostly fat depending on availability, but when you run the number you get what you see in the graph above.
Are these new diets here to stay. I would say YES! More and more studies are pointing towards the benefit of a low-carb diet. Even the New York Time lately had an article on low carb diets. The article starts like this: People who avoid carbohydrates and eat more fat, even saturated fat, lose more body fat and have fewer cardiovascular risks than people who follow the low-fat diet that health authorities have favored for decades. This study actually confirms the result of other studies. This meta-analysis, meaning that it summarized and analyzed the results of multiple studies on low-carb diets, concludes that diets that are lower than <35% carbohydrate, keeping the caloric content the same to higher carb group, had participant lose more weight and increased lean body mass (that also throws away the theory of one calorie is a calorie but that is the subject of another blog).
Mind you these all point out to the health benefit of a low-carb diet but what about performance? That is a different ball game…My next blog will definitely address this conundrum. I will share with you more about my experience with going low-carb. Am I still pre-diabetics??? How does that affect training and racing? You’ll see…

Yogurt: Mother’s Little Helper


No Comments
I like to grow microbes in food. Gross? No, delicious actually.  I used to work in biotech and my job was to grow cells in vessels to make drugs used in clinical trials. Now I ferment stuff in my kitchen, different bugs, same concept. This blog is about fermented foods, probiotics and how to make one of my favorites: yogurt.
Fermented foods are good for you. Humans have been fermenting food for a long time. It was discovered that cheese making was happening in Northern Europe in 7000 BC! From the well known yogurt to kimchi, a fermented cabbage, and sauerkraut, its european counterpart, to the lesser known natto, a fermented soybean from Japan, you can basically ferment anything and everything. Most fermentations use bacteria but yeast can also be involved in the process such as in kefir, kombucha, and beer and wine of course. Fermented food does preserve longer and some of the fiber that could be an irritant to the gut becomes pre-digested thanks to all the little bugs feeding on them. These bacteria, which we also call probiotics, when in the form of a little pill, can colonize your gut and help with IBS and other intestinal issues. If you think about it, we have more bacteria in our body than our own cells and they control much more than we think, talk about alien abduction! Ingesting probiotics has been shown to relieve symptoms of colds and flu,  they are being developed to cure C. Difficile, this hard to get rid bacterial infection, and guess what, the type of bacteria that lives in your body can actually predict if you are going to be obese…Check out this company from San Francisco: Ubiome. For a decent price you can analyze your microbiome and see how it compares with other people. This is on my to do list BTW.  Some compare our gut microbiome to a second brain and these bacteria can actually help with depression and anxiety. They can modulate the expression of  GABA receptors which helps to decrease anxiety, a little bit like a Valium aka mother’s little helper (but different mechanism)! And that is why I eat loooots of yogurt.
Probiotic quality can be variable, the content is not exactly what is shown on the label or it is not very active, so you need to look at the quality control behind it. The strain that you choose is also very important if you want help with a particular issue whether gut, skin or brain related, so be careful and look at the science or ask a good health practitioner. However, for health in general why not make your own probiotic-like food: yogurt.
Yogurt is really simple to make. First you need some really good quality milk. Full fat from grass-fed cows is the best in my view. Here is one study, although done in mice, to show how superior grass-fed milk is. The fact that the composition is higher in plant Omega-3s (alpha linoleic acid) is a good thing…Here is a review on how full fat milk reduces diabetes and metabolic syndrome.
What about homogenization? Some say that reducing the fat droplet size by homogenization can result in an increase in fat bound to casein and whey proteins resulting in increased allergies and risk of cardiovascular disease. It is not proven yet. But me, I’m always a fan of the less processed the better so if I have a choice between the two then I’ll go with the non-homogenized.
Here is my choice:

Where I live I get this milk from the Strauss Family creamery. (Top Secret: This milk can also be found at TJs in my neighborhood under Cream on top milk. Much cheaper) Let’s get back to our yogurt. First you want to heat up your milk to 160-180 F to kill any unwanted bacteria that could “contaminate” your culture. If your milk is fresh from the farm, you can bypass this. Even if it has been pasteurized to remove a lot of the bacteria, as soon as milk is processed and bottled the bacterial count starts going up again while still being very safe to consume. You need to let your yogurt cool down to 110F before putting your culture in.

To culture my yogurt, I like this yogurt maker. It is basically a heated container that keeps the temperature of your yogurt at around 110F. Before I put the milk in, I add my little packet of culture. I like this one which is very mild and soft. You need to reuse a new packet every time. Might not be the most  economical way but it is still cheaper than most yogurt and the best quality you can have. That is your best option, if you are not making yogurt very often. If you are ready for the once a week regimen, you can try this Greek yogurt starter which is reusable. By that, I mean that you use 4Tbsp of your week old yogurt to reinoculate your next batch.

Don’t forget to stir and then let it sit for 4-8 hours. Yes it can be variable because this is not an exact science, we don’t know exactly how many bugs we started with, the temperature might be a little off, etc. You know it is ready when you swirl the container gently and the yogurt swirls with it, it is loosely set. You have to refrigerate it before eating. Here you see the yellowish cream on top.

It is always good to drain your greek yogurt so it gets thicker. I drain it in this container for 2-3 hours in the fridge and what you see at the bottom is whey. Whey consists of the water soluble milk proteins and goes down with the liquid with some of the lactose,  while the casein the other major milk proteins coagulates during fermentation and stays with the fat.  Are you concerned about the environmental impact of all that whey that gets dumped in the environment? Well there are a lot of things you can do with it. You can add it in soil to grow your tomatoes, you can substitute it in a recipe instead of buttermilk, you can use it to cook rice, soak nuts and grains, ferment vegetables, you get the idea.

Here it is. So basically your Greek yogurt is more concentrated in protein (mostly casein) and fat with less of the lactose. What is not to love.  Note that casein is an excellent recovery protein for evening workouts as it digests more slowly and supplies some of the good amino acids for a long time while you sleep…

Are You High on Caffeine?


7 Comments
End of January 2015, are you still on track for your new years resolution? For some it might be losing 5 pounds or stop drinking, for me it is to quit caffeine and write my first blog ever on caffeine effect. I’m still on track to post my first blog ever but did I totally quit caffeine? Not really and here is why.

Maybe you don’t know it but caffeine is highly addictive for certain people. And that applies to me. Caffeine is everywhere. Apart from the obvious, coffee, it can also be found in colas, energy drink and a lot of sports bars and gels.  A cup of coffee can have up to 200mg caffeine, Gu gels vary from 20mg to 40 mg, one of my favorite Pocket Fuel Cold Brewed Coffee Gel has 70mg and Clif shots have a more decent potency with their double espresso at 100 mg. Caffeine can also be hidden in the form of other ingredients such as yerba mate, kola nut, green tea extract, just to name a few.
Caffeine is a plant alkaloid similar to what is in cocaine, nicotine, morphine. All of these being classified as stimulant. The difference is that it is legal, like nicotine. Why? It does create a dependance but it is not life threatening, it can however be life disturbing when you don’t have your cup of joe in the morning. For me, if I did not have access to coffee for a couple of days that would mean seriously bad migraine.
So what makes caffeine so special. A couple of things you might be interested to know without getting too much into the rocket science. First and foremost caffeine stimulates catecholamines. What it means is that it releases adrenaline, noradrenaline and dopamine, and also indirectly cortisol. This hormonal mix creates the fight or flight response and it is believed that this is why it decreases RPE or perceived effort. It also lowers the threshold for muscle excitation. Adrenaline stimulates lipolysis and glycogen utilization, your whole body metabolism gets primed. It is not surprising to see caffeine in most weight loss supplements, as it also decreases appetite through the mechanisms I just mentioned. Most studies show very favorable effect for caffeine. It reduces the time trials in endurance sports in general and increases time to exhaustion during strength training. Who would have known that something so ubiquitous would have such nice effect? Yet I feel it is pretty underutilized.
But studies do vary in their results. And it has something to do with the subjects and how naive were they to caffeine. Because the more used to coffee you are, the less effective it is, you get a blunted output of cathecolamines. Therefore most studies use 24-48 hours with no caffeine or even up to 4 days to desensitize subject. It probably works, but it might not be enough for certain people and it is also probably why such high doses of caffeine are needed, that is 4-6 mg/kg, 30 to 60 minutes before exercise or 200 to 300mg of caffeine for me. For some people it can take up to a month to get rid of the habituation and then caffeine can only be used once or twice a week to really see the benefits.
Another important point is that most of these studies use a placebo but between you and me it is pretty hard not to know that you just had the equivalent of 2 cups of coffee. And as I will explain in another post the placebo effect is a really strong one. If I convince you that caffeine works and have a cup of coffee before your ride, you WILL go faster. Crazy.
So why did I decide to quit caffeine? So I could try it as an ergogenic during training and racing and really know if it was working. It took me a month to get off it. For some people going cold turkey might work but it did not for me, for the reason I mentioned earlier. I gradually decreased my amount to finally go caffeine free coffee. I really like the taste of coffee and it is some sort of ritual so I still have it in the morning in the decaffeinated form. I use this decaf bean from Bulletproof. They claim that they use a mycotoxin free bean and they use the Swiss water process to take out caffeine, which is a chemical free process compared to decaf you can get at Starbuck and the likes. It is more expensive though…
So now here I am caffeine free! And I feel like I’m in rehab, some days it is hard. But being caffeine free made me realize how sleep deprived I was. Also, I realized how caffeine was making me nervous and gave me the jitters. Now I have a large cup of coffee usually on Saturday morning before my big ride of the week, it is probably at about 150 to 200mg. Sometimes I do the Bulletproof thing, which is no longer a secret as Runner’s world and The New York Times published articles on this. It consist of coffee, a tablespoon of butter and MCT oil. Good stuff. After that I feel like superwomen. 6:30AM Saturday morning and I am ready, I start jabbering so much that my husband asks me what is wrong with me, I feel euphoric, I am hot and sweaty (literally). Hop on the bike and I hammer those pedals. Zone 3 feels like zone 2, my watts are up the roof, it is working. After 2 hours, I feel a little bit of a slump, I go for another dose (Pocket Fuel Cold Brewed Coffee Gel, 70 mg). I’m a junky. I crank up the music in my ear buds and smile for the rest of the ride. Is the effect real? Is it placebo? Maybe a little bit of both
Here it is my first blog. Hope you like it!
