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 It’s the vicious cycle of dieting that is exhausting, discouraging, and frankly outdated.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.

Do you ever wonder why you do the things that you do with food? “Why do I overeat? Or why do I restrict? Or why do I do both?” Maybe you’ve started to notice that it’s not really about the food or your body - but then what is it actually about? As a Nutrition Counselor, Registered Dietitian, and Adjunct Professor at NYU (& former people pleaser and perfectionist), I understand the discomfort and the struggle - and the shame or guilt that often follows. I understand wanting to feel confident & comfortable in your own body without feeling like food has this “power” over you.
