Thanks for all your great nutrition counsel! The devil is in the details for sure. Most of us athletes have heard a lot about what we should be doing, but I guess not many know how to actually apply it to our individual situations, other than trial and error. It’s hard to isolate the factors so what I found over the years was mostly error….never cracking the code. You helped me with your “code” cracking and helping me stay accountable.

The result of our work this past year was four minutes and 22 seconds improvement over my last PR at the half iron distance. And, the day was windier on the bike than usual, so the improvement was actually greater.

We trained my body for better metabolic efficiency and overall I ate less and felt better. Oh, and I did I add that although it wasn’t my goal, I lost weight and became leaner to be meaner for the race!! Thanks!

Isabelle began working with me for the 2017 triathlon season. I really appreciate her approach of collecting information about my past experiences and then providing specific, quantitative recommendations along with a logical explanation for these. She specifically helped me understand nutritional solutions at the latter part of long course races. I learned a lot from working with Isabelle this year and look forward to continuing my nutrition education in 2018!

I worked with Isabelle in January 2016. I have struggled with gastro-intestinal (GI) issues at 70.3 and 140.6 events. In working with Isabelle I learned easy way to incorporate more protein and real foods into my diet and moving away from processed foods during the day and Gu during my races. I also took the metabolic test which was life changing. We learned I am a great fat burner and did not need nearly the calories I had been consuming during training and races. I have moved to only taking on about 180 calories on the bike and this seems to resolved my GI issues on the run. In addition, I think all her nutritional support this past year has helped me to reach my first two podium finishes in Olympic Triathlon races!  I am excited to prepare for my next 140.6 with all my new knowledge from Isabelle!

Before working with Isabelle at INprove.me, I was a dietary train wreck in all capacities of eating, not just performance eating. She has not only corrected my unhealthy habits but provided a non-cookie cutter way (no pun intended) for me that has lead to improved race results especially in the long course.

Isabelle helped me figure out after several years of racing with stomach issues that I was taking in too many calories. The metabolic testing was  key and she carefully went over the results with me afterwards.  I also have worked with Isabelle for an injury post surgery and she guided me through specific food choices and supplements to aid in recovery.

Many things can go wrong in an Ironman, nutrition is not one anymore. After finishing an Ironman 70.3 race where I had to go to the bathroom several times I decided that I had to start paying attention to nutrition during races. I contacted INprove.me seeking help for my first IM nutrition plan, not only for race day but also to improve my daily habits. Nutrition was the biggest unknown on my first Ironman race, nutrition plan had worked during training days but race day can always bring surprises. My first Ironman went great, no bathroom stops, not even stomach cramps. I have kept working with Isabelle and I have completed to date 4 Ironmans (including 1 Kona) with no bathrooms stops or any performance decrease due to nutrition problems. Furthermore not only nutrition is not a concern anymore but we have used it to improve my performance during training and racing.

When I sought services from Isabelle, I had 3 goals/concerns in mind:  to obtain assistance with what to eat before and after training days, competitions and rest days, to loose body fat and to break what I considered my addiction to sugar.  Not only did Isabelle help me reach those goals and answer my questions, she also assisted me in multiple ways that I didn’t even imagine…from having my PCP do lab work and identifying some deficiencies to even helping me adjust my young daughter’s nutrition.  Isabelle is so easy to work with, incredibly knowledgeable and able to assist with problem solving and road plateaus.  And not to mention, she walks the talk for her own competitions.  An inspiration.  I would recommend her services to anyone, and have done so!

I started working with Isabelle a year before my first Ironman race. I reached out to her to help me with my overall diet while training for this event plus the race nutrition itself. Isabelle did not just tell me what to eat or do but she took the time to understand my habits first. She also educated me on why we were making these changes. Later that year I had a successful race!

The only nutritionist you will ever need for your athletic career is Isabelle Nadeau. She keeps up to date with all the latest athletic nutrition research and offers lab testing for metabolic efficiency which is amazing . Whether you are trying to lose weight, gain weight, gain power, or just increase race performance in general, I would highly recommend her. She has me training and racing at a much higher caliber than I could have done on my own.

Isabelle shared with me her expertise and knowledge about nutrition and exercise. At 40 my body had really started to change and she helped me figure out ways using healthy food alternatives to decrease bloating and have more energy! I am so grateful to her!
