The Claim

In men with visceral obesity, a 1-year lifestyle intervention involving caloric restriction and increased physical activity results in significant improvements in visceral adipose tissue volume, leptin levels, and circulating 25(OH) vitamin D concentrations.

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

In plain English

If a man with excess belly fat eats less and moves more for a year, his belly fat, hunger hormone levels, and vitamin D levels all get better.

  1. Study: Relationships between circulating 25(OH) vitamin D, leptin levels and visceral adipose tissue volume: results from a 1-year lifestyle intervention program in men with visceral obesity

    The study gave overweight men a year-long plan to eat less and move more, and it worked: their belly fat went down, their leptin levels dropped, and their vitamin D levels went up — just like the claim said.
