This statement by Dr. Gabrielle Lyon isn’t just catchy—it’s scientifically sound. A 2024 Scientific Reports study analyzing nearly 11,000 adults found that a high lean mass to visceral fat ratio was tied to up to 88% lower risk of type 2 diabetes and significantly fewer cases of high blood pressure and abnormal cholesterol levels.

A 2025 study in Frontiers in Nutrition found that people with more muscle and less visceral fat had up to 61% lower risk of kidney stones. The link held steady even after adjusting for age, BMI, and health status.
