Vegan Diet Rapidly Improves Type 2 Diabetes Markers in Adults

In overweight adults with no history of diabetes, a low-fat, plant-based vegan diet can reduce visceral fat and significantly improve both pancreatic beta-cell function and insulin resistance, potentially decreasing the risk of type 2 diabetes, according to researchers.

The 16-week randomized controlled trial in 73 adults showed that participants who ate a diet of vegetables, grains, legumes, and fruits significantly improved their overall metabolic condition, say Hana Kahleova, MD, PhD, of the Physicians Committee for Responsible Medicine in Washington, DC, and colleagues.

“Our study suggests the potential of a low-fat plant-based diet in diabetes prevention, addressing both core pathophysiologic mechanisms — insulin resistance and diminished beta-cell function — at the same time,” they write in their article, published online February 9 in Nutrients.
