Chicago's Weight Loss Leader!

Weight Loss Resistance? 

Discover the FUNCTIONAL approach to rapid weight loss that is simple, customized, & highly effective!

...Even if you've tried EVERYTHING!



*** IMPORTANT - Our Functional Weight Loss System CAN Be Done From Anywhere!


71% Of The Entire United States Is Either Overweight Or Obese?

100 MILLION Americans Are Either Diabetic Or Pre-Diabetic?


From the desk of Dr. Grossman:


The vast majority of weight loss programs are 1 size fits all. They are "generic". They are "cookie cutter" which means everybody gets the same thing. 

Friends, we are all DIFFERENT

We are all UNIQUE!

Each and every one of us reacts and responds to foods differently

Keto / paleo / plant based / whole food etc. may work wonders for some, yet could be your worst nightmare! 


If you're totally confused about what to eat, when to eat, how much to eat, what supplements to take, what foods to avoid etc. (in order to kick your fat loss into high gear), then it's time to watch the mini masterclass!

No Cost - No Obligation. Simply a chance to learn more about functional weight loss and why it works so well for so many people. 

My name is Dr. Elissa Grossman and I've been helping patients in the Chicago area lose weight for over 15 years! I'm a functional medicine specialist and have a passion for helping patients lose weight and get healthy in the process. 


Most weight loss programs DO NOT take cellular health into consideration. They do not take cellular INFLAMMATION into account. Friends, it is next to impossible to lose weight when you're inflamed! We must take a "global" look at your lifestyle.

THIS is why we get such amazing results with patients! 

Our Clinically PROVEN Protocol Is Simple, OBJECTIVE, & Highly Effective!

Our functional weight loss is unique, CUSTOMIZED, & tailored to YOU!

Our functional weight loss protocol is the culmination of 15 years of testing, tweaking, refining, researching, & mastering a protocol that simply works! 

Functional weight loss is not guesswork. In our clinics we have a saying..."We Don't Guess...WeTEST!"

This provides our patients with an extremely high success rate!


Many weight loss programs revolve around short-term calorie restriction. While this may provide some success in the short-term, it WILL NOT provide a sustainable RESULT for you long-term. 

We pride ourselves on providing patients a "lifestyle" based approach that is simple, comfortable, and sustainable! 

Again, we provide a functional approach to weight loss that simply works!
