Forever Strong: A New, Science-Based Strategy for Aging Well

After years of watching patients cycle through her practice, Dr. Gabrielle Lyon noticed a pattern. While her patients struggled with a wide range of conditions, they all suffered from the same core problem: they had too little muscle rather than too much fat.

When we think about muscle, we tend to think about strength or aesthetics, but in reality, muscle accounts for so much more than that. As the body’s largest endocrine organ, muscle actually determines everything about the trajectory of health and aging. Many of the conditions Dr. Lyon’s patients were experiencing were actually symptoms of unhealthy muscle.

Now, Dr. Lyon offers an easy-to-follow food, fitness, and self-care program anchored in evidence and pioneering research that teaches you how to optimize muscle—no matter your age or health background. Discover how to overcome everything from obesity to autoimmune disorders and prevent diseases like Alzheimer’s and hypertension by following Dr. Lyon’s powerful new approach to becoming forever strong.

Learn how to reboot your metabolism, build strength, and extend your life with this accessible new guidebook that demonstrates the importance of muscle for health and longevity from the founder of the Institute for Muscle-Centric Medicine.

The Mission with Forever Strong:

This book is my life’s work and mission to help you and the world optimize your health and improve your quality of life through my concept of Muscle-Centric Medicine.

Today’s medical paradigm continues to focus on battling a problem like fat rather than preventing a problem by building muscle and prioritizing protein. The fat story is about restriction, and the muscle story is about strength.

What would happen if we got that working model wrong?

Exactly what you would expect, we would spend 50 years trying to correct the wrong problem of obesity. Fifty years without improvement and, in fact, 50 years of people getting fatter and sicker. 73% of adults are overweight or obese. And outside of smoking, obesity is a major leading cause of death.

Why are we still not making progress?

I believe it is because these issues are a muscle problem, not a fat problem.

Together we are going to fix this.

We are not overfat. We are under-muscled.

We’ve been asking the wrong questions and trying to solve the wrong problem of body fat. That changes today.
