At the New York Bariatric Group Medical Weight Loss Program, we have a unifying philosophy that takes the wishes of the patient into consideration when creating a comprehensive weight loss plan. We see each component of weight loss as a tool and our aim is to apply the right tool to accomplish the goal. By offering medication, gastric balloons and surgical options, each patient can rest assured that they are receiving the best approach to help them achieve their goal of being healthier. Our physicians utilize the latest evidence-based techniques so that our patients can benefit from the most up-to-date treatments.

The Program

Using our onsite nutritionists, we can create a comprehensive medically supervised weight loss program tailored to the patient’s individual needs. We offer several different options. For patients who seek rapid weight loss, we utilize carefully developed nutrition products to implement a very low-calorie diet. This diet usually lasts 8 weeks and is an induction phase to jumpstart weight loss. Once complete, our nutritionists help craft an eating regimen for continued weight loss.

For patients looking for slower, sustainable weight loss, we devise a diet regimen to help patients permanently alter how they approach food. Using the most recent scientific research on habit change, we will help patients develop a sustainable eating program complemented by an exercise program.

Our comprehensive program incorporates a physician specializing in the use of medication for weight loss, nutritional guidance, and expert fitness assistance. This combination will help ensure all patients receive the right balance of help to reach their weight and personal goals.

Ease of Access

To make it convenient, The New York Bariatric Group has developed a virtual healthcare portal and iPhone/Android app with the ability to make your appointments with the nutritionist. You can have a one-on-one video nutrition session on your phone or computer from the comfort of your home. There are also live streaming nutrition and fitness classes as well as an extensive library of prerecorded videos.

Our comprehensive programs can help you work to achieve your weight loss goals.

I hit my goal weight ... and I feel fabulous

I had the gastric bypass. I am Type 2 Diabetic and I wanted to gain control of my sugar. I hit my goal weight in about 5 and half months and I feel fabulous. The procedure has completely changed my life for the better because it has empowered me as a middle aged woman that I can really do everything and anything that I want to do. I don't put an age on anything. I don't say I'm too old for something.

Robert's success story

I was tired of the way I looked. I was tired of the way I felt.

I knew if I didn't change something soon, I was going to be in a lot of trouble. The consultation process was a lot easier than I expected. I was met with open arms. I was treated like I was the only patient here. Not only did they answer all of my questions, they had questions for me to make sure I was the right candidate for the surgery. After surgery and that weight started dropping off, my life started changing for the better.

I had the gastric sleeve procedure. The driving factor behind me getting this procedure was my health. I didn't feel good physically or mentally.

I feel like a completely different person. I feel stronger. I feel able to accomplish more.

Eileen's success story

It saved my life.

The driving factor behind me getting my procedure was that I couldn't get up off the floor with my granddaughter. That was my why. That was my big reason for having this surgery done. After surgery, it was a little bit of a struggle with what to eat. What you put in your mouth that you don't even think about. You don't think about what you're eating or how you're eating and portion size. It's what I do now every single day. The procedure has changed my life in so many ways. It saved my life.

I am totally comfortable in my own skin.

I think I always grew up identifying myself as less than other people because I was fat. I decided to tackle that and just live my life. I had a sleeve gastrectomy. It changed how I view myself. How I communicate with people. I'm able to be much more of myself and live the life I always thought I should have been living. I am totally comfortable in my own skin. You have the tools you need to succeed here.
