The Registered Dietitians at Nutrition in Motion share a philosophy of using food to fuel, nourish and strengthen one's body. We treat each patient as an individual in order to collaboratively create a plan to reach the individual's goals. We believe in the use of behavior modification in conjunction with nutrition counseling, rather than attempting to follow an unsustainable diet. This helps clients make more attainable and enduring lifestyle changes. All foods can have a place as a part of a healthy lifestyle, and we are here to help you make them fit.

Do you struggle with losing stubborn weight? Let us guess. You’ve tried numerous diets, calorie counting, cleanses, and meal replacements and although they may help at first, ultimately they all just lead you back to where you started. Do you feel that even when you’re trying to be “good” the scale just seems to reflect otherwise? If this all sounds familiar you are not alone and we are here to help you. It’s NOT you we promise. It’s the vicious cycle of dieting that is exhausting, discouraging, and frankly outdated. This is why at our practice we take a different approach to weight loss, one that’s evidence based AND sustainable.
