As a newly-diagnosed Type 2 diabetic, I couldn’t figure out how to fuel my running adventures without consuming massive amounts of sugar and throwing my system out of whack for days. Dina helped tailor my nutrition & training program which enabled me to understand my day-to-day blood sugar fluctuations and to maintain better control through diet and exercise, insomuch that I’ve been able to eliminate the need for one of my medications. Dina’s role was critical in transforming me from an out-of-control, roller coaster runner to an even-keeled, healthy & energetic athlete... and I achieved my goal of completing my first 50-mile ultra trail race!
