The Claim
In men with visceral obesity, a 1-year lifestyle intervention resulting in reduced adiposity is associated with a 27% increase in circulating 25(OH) vitamin D levels and a 27% decrease in leptin levels, and the change in vitamin D levels is independently associated with the change in leptin levels after adjusting for changes in visceral, subcutaneous, and total abdominal fat mass.
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.
When overweight men lose body fat through lifestyle changes like diet and exercise over a year, their vitamin D levels go up by about 27% and their leptin (a hunger hormone) levels drop by 27%—and these two changes seem to be connected, even after accounting for how much fat they lost in different parts of their body.

What the research says
1 studyThe study gave overweight men a year of diet and exercise advice, and their vitamin D went up by 27% while their leptin (a fat-related hormone) went down by 27% — even after accounting for how much fat they lost. This matches exactly what the claim says.
