Our Philosophy | RDN Nutrition New Jersey

Whether you are looking for bariatric nutrition, approval for bariatric surgery, or just help with knowing what to eat to stay healthy, The New Jersey registered nutritionists at RDN Nutrition are in your corner. We will provide you with the counseling, meal plans, and guidance you need to keep your weight under control as long as you need us.

What is morbid obesity, and why does it matter?


There is a difference between somebody calling you “fat” and being classified by a medical professional as morbidly obese.

While we embrace the spirit of body positivity, RDN Nutrition vehemently disagrees with the idea that those who are morbidly obese should just “accept” dying young. We believe in your ability to live a full, rewarding life without succumbing to the health issues associated with morbid obesity.

At RDN Nutrition, we classify morbid obesity as a BMI over 35. There is plenty of room for different body types under that number. However, if your BMI is over 35, you are morbidly obese and could be a candidate for bariatric surgery.

Bariatric Nutrition New Jersey

Bariatric Nutrition

To be qualified for bariatric surgery, you must be able to show that you have exhausted nonsurgical options to reduce your weight healthily through bariatric nutrition.

The New Jersey bariatric dietitians at RDN Nutrition are the only nutritionists in the area to receive an endorsement from the Academy of Nutrition and Dietetics, the American Society for Metabolic and Bariatric Surgery, and The American Association of Bariatric Counselors. If you need bariatric surgery, we will help you get approved. But approval for surgery is only the beginning of his bariatric nutrition process. Our goal is to help you through surgery and recovery with specialized post-surgery meal plans that optimize healing. Following recovery, our post-surgery bariatric nutrition plans will teach you how to keep the weight off for life.

General Nutrition Counseling New Jersey

General Nutrition

While RDN Nutrition works closely with patients on the path to bariatric surgery, we also help patients live healthier lives by incorporating good general nutrition into their daily habits.

Our media and pop culture love to tout the next great diet plan. The truth is, when it comes to general nutrition, the best “diet” is no diet at all. Our New Jersey general nutrition dietitians offer customized meal plans and bespoke nutritional guidelines tailored to your specific needs. We believe nutrition is a conversation. If there are foods we recommend that you hate to eat, we know you probably won’t eat them. Our goal is to make your general nutrition plan one you can live with for a long, long time.
