What’s your journey?

Excess weight is a chronic medical condition, not a lack of willpower. It can result from a variety of underlying biological factors including hormonal, metabolic, and genetic factors.

It's difficult to lose weight.

It could be genetic.

There are 125 different genes that contribute to your metabolism,
any of which could be making it harder for you to lose weight than somebody else.

It's hard to keep it off.

It could be your 'Set Point'.

If you have success dieting short term, but when you stop your weight snaps right back, the reason is biological.

During weight loss, your body lowers your metabolic rate to make it easier to regain the weight. New research has shown your body seeks to return to it's highest weight, or 'Set Point'.

Nothing works.

It could be biological.

After multiple weight loss attempts, aka yo-yo dieting, you no longer see any weight loss even during extreme dieting.

The reason is every time you lose more than 5% of your body weight, your levels of naturally produced GLP-1 drop, triggering dramatically increased hunger.

When GLP-1 levels are low, calorie restriction is unattainable because you’re so hungry.

You don’t need to feel hungry to

After gaining and losing weight my entire life I finally met the right person to help me maintain permanent weight loss. Dr. Nancy not only helped me lose the weight but she helped me understand my personal reason for losing the weight which has helped me maintain it for over 2 years.

Mike P.

I was 49 years old, 230 pounds and suffering things brought on by my weight like high blood pressure, and inconsistent sleep. Dr. Nancy overhauled my diet and gave me a better awareness of what my body was telling me. Today, at 53 I’m now 183 pounds, and I have a better outlook for the future.
