Dan Go, the fitness entrepreneur known on X as @FitFounder, said getting 30 minutes of sunlight daily is one of the most underrated strategies for fat loss. He made the statement in a post on X that quickly gained traction with over 90,000 views.

“Sunlight helps your body make vitamin D, which can shrink fat cells and stop your body from storing extra fat,” he wrote. “Vitamin D may also help control hunger and boost metabolism, making it easier to burn fat and lose weight.”

Vitamin D has been shown in some studies to influence adipocyte (fat cell) behavior, and low levels of vitamin D have been associated with higher body fat percentages and increased appetite regulation issues. A 2011 study in Nutrition Journal found that vitamin D supplementation in overweight individuals led to modest reductions in body fat.

According to the National Institutes of Health, vitamin D is produced in the skin in response to UVB rays from sunlight and plays a key role in bone health, immune function, and metabolic regulation.
