Weight training and cardiovascular exercise are not complete without proper nutrition. What you eat accounts for 85% of the outcome in training! D21 regards nutrition as “Good, Better, Best.” We believe that no food is “all bad,” but there are ways of finding the “Good, Better, Best” in what you like to eat and what you should eat.

We start by assessing your current eating habits and identifying the “Good.” Then, we help you identify food choices from “Better” to “Best” so that you can sustain healthy eating habits that are compatible with your fitness goals.

Nutrition Workshop Testimonial

“I recently had the pleasure of participating in Deborah Stern’s nutrition workshop at D21 Fit Studio. Deborah is a high energy trainer and nutrition coach with a very straightforward & engaging approach to eating right. My take away from her workshop is that there are many great tasting healthy food options available for those of us who strive to stay fit & eat right, yet still have a tough time giving up our guilty food pleasures!

As I confided to Deb, I grew up having dessert every night & have found it difficult to forego my nightly sweets. She explained to me that there are many healthy & satisfying options available which would not end up making me feel lethargic & craving even more sugar. She gave me some creative options to replace my sweets with and invited me to then sample her assortment of “Deb Approved” snacks. They tasted amazing & satisfying. I’ve since incorporated them into my daily diet, shared them with my family. Thanks to Deb, we’ve all been enjoying an increased energy level!”
