Medical Nutrition Therapy

A national leader in the field, the BMC Nutrition and Weight Management staff is dedicated to promoting healthy weight through medical nutrition therapy (MNT). MNT manages a variety of diseases by combining nutrition diagnostic, therapy, and counseling services. It goes beyond basic nutrition education. This holistic care model helps patients reach their goals through customized eating plans, behavioral support, and exercise.

Weight Management

An estimated 45 million Americans go on a diet each year, and Americans spend $33 billion each year on weight loss products. Yet, nearly two-thirds of Americans are overweight or obese. Obesity is a chronic disease that requires lifelong treatment and medical care.

Refer a Patient

We are committed to providing a high level of assistance to our physician colleagues within BMC and outside of the BMC system, as well. Whether for diagnostics, treatment, a single consultation, second opinion or ongoing follow up, our physicians will keep the consulting physician fully informed of the patient's treatment plan and coordinate long term management.

Free Virtual Patient Orientation Session

For most weight management patients, the first appointment will be a virtual group class taught by one of the Registered Dietitians. The class will introduce eating strategies to help you make sustainable lifestyle changes. Following the virtual class, patients will meet with an obesity medicine specialist and  dietitian individually to assess immediate and long-term nutrition needs and create an individualized plan. This plan will take into account any potential medical issues, as well as personal lifestyle choices. Subsequent appointments will be scheduled as needed to assess progress, provide support and additional counseling, or to modify the plan. 

Research Overview

Our weight management and nutrition team is  actively engaged in research including obesity and fatty liver disease and therapies for short bowel syndrome . We provide many opportunities for patients to participate in clinical trials.
