Nutrition in Recovery Mission Statement:

Nutrition in Recovery is dedicated to the promotion of both physical and nutritional wellness as primary components of all forms of recovery. By incorporating a highly specialized Registered Dietitian Nutritionist as a member of the treatment team, Nutrition in Recovery aims to bridge the gap between nutrition and mental health. Through informing and encouraging behavior change with respect to food, Nutrition in Recovery will help contribute to positive long-term outcomes. We work with people not “in recovery” and always aim to meet people where they are at.

Nutrition in Recovery

Prompted by his extensive research and inspiring case studies, David Wiss discovered that nutrition is a poorly understood and frequently ignored component of treatment during rehabilitation from substance abuse.

In 2012, Mr. Wiss founded Nutrition in Recovery and developed a detailed curriculum that provides specialized nutrition services to individuals and treatment centers.

Nutrition in Recovery is located in West Los Angeles, California with options for mobile and virtual treatment as well. Nutrition services are available for both treatment centers and individuals anywhere in the world! 

From David

“I talk about nutrition in a way that most people have never heard before. My emphasis goes way beyond calories and macronutrients. I help people explore the profound impact that food has on the brain, the gut, and the endocrine system (hormones). I am a behavioral health nutritionist, recognizing the challenges faced when attempting to make positive health changes. I will help you on the path to a new way of life. If you struggle with food and/or body image, Nutrition in Recovery is the program for you. I will show you how to navigate the food supply with confidence. There is no “one size fits all” approach to recovery. I will help you to figure out what the right solution is for whatever you are struggling with. I will give you the truth! I look at the entire dimension of physical wellness: food, water, exercise, sleep, sunlight etc. If you are struggling with caffeine, nicotine, etc. I can help you break free. My expertise is in nutrition but my passion is recovery. I love to see people rise up.”
