Root Concern
Excess Weight
Gut Health

More than 50% of Americans struggle with excess weight. Whether the root of the issue is genetic, lifestyle, or hormone imbalance, we understand that weight loss is difficult to attain and even more difficult to sustain.

How we treat

Through detailed analysis and diagnostic testing we customize a medical weight loss plan unique to you. Each plan targets nutrition, hormone, gut health and micronutrient optimization, combined with accountability and lifestyle modification that works with your body for the long term.


Symptoms of chronic reflux, bloating, constipation, or diarrhea all indicate a compromised gut. Poor gut health is a significant contributor to a slow metabolism, excess weight, chronic fatigue, a compromised immune system, micronutrient deficiencies, hair loss and even mood disorders.

How we treat

Specialty testing in addition to customized elimination plans helps identify the root issue contributing to gut health disorders. Testing options include food sensitivity & food allergy testing, gut microbiome evaluation, Candida or bacterial overgrowth (SIBO), and poor digestion, poor absorption and dysbiosis. 


Hormone imbalances can contribute to weight gain, chronic fatigue, mood imbalances and many other conditions. Many hormones have a large range considered normal.  Our goal is not just to normalize hormone function, but to optimize it.

How we treat

With diagnostic laboratory and saliva testing in combination with a complete symptom assessment, we are able to identify the hormones that need to be optimized. This frequently leads to resolution of physical complaints and leads towards healing.


Our modern lives often lead to sleep deprivation, chronic stress, poor food choices and eating behaviors in combination with toxin exposures, such as alcohol, all contribute to multi stage ailments, such as poor gut health, mood disorders, increased appetite, increased weight gain and poor metabolic function. 

How we treat

Through lifestyle modification coaching, we are able to encourage you to make better behaviors and more beneficial habits. We’ll help you understand what’s going on in your body, and help guide you to a healthier lifestyle.


Chronic fatigue, weight gain, low motivation, feelings of helplessness and a compromised quality of life are all indicative of a slow metabolism.  Your metabolism contributes to the likelihood of storing fat and the cascade of events that result from excess weight. 

How we treat

We help you understand the factors that contribute to a slow metabolism and make appropriate changes, motivating better habits that lead to sustainable success.  We also help improve your metabolism by optimizing nutrition, hormone function, gut health, micronutrients, and muscle mass.

Hello, I'm Dr. Nancy

My approach combines nutrition, lifestyle and cutting-edge science to optimize your body. I’m an Internist and Obesity Medicine specialist practicing Bariatric Medicine. I view nutrition as a gateway to health, that can be the solution to physical ailments and chronic diseases.

During my medical training, I learned how to properly teach lifestyle modification and performed clinical research into the behavior of foods within our bodies. As a resident at Cedars Sinai, I would walk into a 30-hour shift with my lunch box, and my yoga mat. In my practice, combining evidence-based medicine with behavior modification coaching and the principles of Eastern medicine has allowed me to help many people achieve health goals they believed out of reach.

At Dr Nancy, we practice Bariatric Medicine, to help patients optimize wellness with simple changes in their daily routines. Our goal here is simple: to empower you to live your best life and achieve sustainable health.

In good health,
Nancy Rahnama, MD
