The Claim
In men with visceral obesity, a 1-year lifestyle intervention that results in a 26% reduction in visceral adipose tissue volume is associated with a 27% reduction in leptin levels and a 27% increase in 25(OH) vitamin D levels.
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.
If overweight men lose a lot of belly fat over a year by eating better and moving more, their hunger hormone (leptin) goes down and their vitamin D levels go up — both by about a quarter.

What the research says
1 studyThe study gave overweight men a year of diet and exercise advice, and their belly fat, leptin (a fat hormone), and vitamin D levels changed exactly as the claim says — belly fat went down 26%, leptin dropped 27%, and vitamin D rose 27%.
