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 It’s the vicious cycle of dieting that is exhausting, discouraging, and frankly outdated.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

Medical Nutrition Therapy (MNT) Nutritionists and Dietitians

What is medical nutrition therapy?

Medical Nutrition Therapy (MNT) involves the use of personalized dietary changes to prevent or manage chronic conditions. Typically conducted in an outpatient setting by a Registered Dietitian (RD), MNT aims to address specific health issues through tailored nutrition plans. Clients are often referred for MNT by healthcare professionals who identify conditions that could benefit from dietary and lifestyle modifications, such as diabetes, hypertension, or cardiovascular disease. The goal of MNT is to improve overall health outcomes by making adjustments to the client's diet based on their individual needs and medical conditions.

What conditions is medical nutrition therapy for?

Medical Nutrition Therapy (MNT) is often used for individuals with diseases caused or worsened by poor diet, such as type 2 diabetes, hypertension, kidney disease, and cardiovascular diseases. However, other conditions can also benefit from nutrition therapy. MNT is typically not intended to replace other treatments, such as medication, but rather to complement them. By improving a person's overall diet and health, MNT aims to prevent the exacerbation of symptoms and complement other treatments.

Is medical nutrition therapy covered by insurance?

Medical nutrition therapy is frequently covered by insurance. However, insurance coverage can vary based on factors like your specific plan details, whether you choose an in-network or out-of-network provider, and whether you have a referral for nutrition services based on a medical diagnosis. While a referral is not required to see a dietitian or nutritionist, and many individuals independently seek nutritional support without prior medical advice, a referral from a primary care physician or another medical professional may be necessary to obtain coverage for medical nutrition services. In such cases, a referral is typically made for those who have been formally diagnosed with a medical condition requiring nutrition counseling, such as diabetes or hypertension. Coverage also depends on the type of nutrition service. Typically, insurance plans only cover services provided by a licensed Registered Dietitian (RD) and do not cover those offered by nutritionists or nutrition coaches without the RD credential. If nutrition services are not covered by your insurance, some dietitians and nutritionists may offer sliding scale rates or lower-cost services for clients who cannot afford their full fee.

What does medical nutrition therapy involve?

The approach a dietitian will take in a medical nutrition therapy session will depend on a number of factors, including what conditions the client has and what the goals of the client are. An initial session often involves an assessment of the client's overall health and current dietary intake; a dietitian may also speak with a client's medical doctor prior to or following a first session to obtain information on the medical condition(s) the client is seeking nutrition therapy counseling for. The dietitian will then work with the client to create goals of medical nutrition therapy sessions, such as weight loss, eating a more plant-based diet, or reducing sodium intake. Then, in ongoing sessions, the dietitian will work with the client to meet their stated goals. These ongoing sessions often include menu planning and coaching, which involve the dietitian working with the client to develop strategies for a healthier and more balanced diet. Dietitians may suggest recipes, put together grocery shopping lists, and/or recommend tracking one's intake in order to help clients make desired changes.
