What People Are Saying About Nancy Clark:


I really want to thank you for all of the advice and information you gave me in our meeting last month. I have noticed a tremendous difference in the way I feel both while exercising and just during the day. I really think this has helped me alot!!
The amount of advice you gave me in that one session really has made a huge impact thus far!!!

Best regards, Caroline, US Olympic Trails Marathon Qualifier

I want to thank you again for your nutrition coaching and guidance. After meeting with you and applying everything I learned, I went on to have a successful season thus far. I first qualified for the World Half Iron Championships, then I PR'd by 30 minutes at my Ironman in Germany and qualified for the Hawaii IM. I worked so hard physically this year, but nutrition was the final piece and I learned so much from you. I feel like I finally had some good races. I am also 7 lbs. lighter, and more confident with my body.

Sincerely, Jen Scalise, triathlete

I want to let you know how well I did in my race on Sunday- better than I expected! The race was 10 miles and I was hoping to complete it in 1 hour and 40 minutes; I finished in 1 hour 28 minutes! I was sooo glad! I had wheat toast with honey and egg whites at 6:00 in the morning and then a banana and peanut butter an hour before the race. I felt really good the whole race; it was a great experience! You have helped me tremendously, and I can't wait to see you again!

Sincerely, Andrea Cote

Dear Nancy,
Thank you for all the excellent advice you gave me during my visit with you. I PR'd by 15 minutes at the Boston Marathon and I feel that your advice made the difference ... I was well fueled! This demonstrated to me how important nutrition is.

Sincerely, Cara


Dear Nancy,
I just wanted to let you know about the success of my new and improved sports diet since we met two months ago. I feel so much better now and I have so much more energy. I'm eating more calories earlier in the day and drinking less coffee. I never feel really hungry. The best part is the food changes have a positive effect upon my running. I recently set a PR!! Thank you for all of your help and support. Your recommendations were excellent and just what I needed.

Sincerely, Amy

Nancy, I just completed my 8th marathon and I felt great before, during and after. I re-read my nutrition bible (your "Food Guide for Marathoners") before I began training and then, again, as the marathon approached. You made eating simple, nutritious, delicious and effective! Even my recovery got on the fast track. Thanks for making nutrition-for-marathoners something that us mere mortals can incorporate into our lives with ease!
Kathy Ball-Toncic

Dear Nancy,

I met with you a few months ago—I am the guy with the very busy work schedule who likes to run, hike and bike. I am 35 years old and have always worked out. You gave me great common sense advice and have helped me make smarter dietary decisions.. I have gotten more from my workouts since meeting with you and am working out with more energy. Thank you!

Mike from Duxbury MA

Dear Nancy,

I want to thank you for all of your insight when we met last week. I left your office feeling confident about my food plan. I felt totally comfortable being 100% honest with you about my eating habits. That is generally a really hard thing for me to do. It was the first time I actually listened without my eating disorder screaming at me, saying "Yes, but..."

I didn't leave feeling pressured or overwhelmed which, in the past, is how I felt every time I left nutrition appointments. I have been able to take on some of the changes you have suggested without feeling like if I didn't succeed, I have failed. If I don't succeed one day, I will try again the next.

These changes are challenging yet rewarding. I had a great long run on Saturday and I know that the small changes I made Friday and Saturday morning contributed to that improvement.

I appreciate your profound understanding of eating disorders and sports nutrition. I look forward to meeting you again.

Runner in the Boston area.


Nancy, I am so glad you are seeing my daughter. She talks very positively about working with you. And, she says, you REALLY know your stuff!

Mother of a collegiate athlete


Hi Nancy,

I have been following your plan since last night. Today, on my 12-mile run, I flew like I used to many years ago. It was not my legs or extra weight making my workouts feel so strained; I did not have any fuel in my gas tank! I have gone from discouraged to very hopeful. Thank you so much for your help.

Ron, a 57 year old runner


Yes, I can absolutely say good nutrition contributed to my successful cross-country season. I feel energized during runs and less cranky afterwards. Thank you for helping me reach my goal.

Collegiate cross-country runner


Dear Nancy,

I really enjoyed your presentation on "Women, Weight & Exercise." I did not think I would leave there with three pages of notes!
I liked not only the messages you presented but also how you stated the messages. One phrase that stood out was how you said 'Food is a religion. There are many different religions and I respect them." 
Thank you for helping enhance my knowledge in this field of study.

Wow, Nancy, did we need your sports nutrition workshop! The athletes all said it was the most helpful nutrition talk they had ever had. I have to say that I noticed immediately this morning they seemed to have more energy. Today is the recovery day after a tough speed workout yesterday, For the athletes to have more energy is a significant change. THANK YOU for everything!

Ellen Minzer, US National Para Rowing Team Coach
