The Claim

Caloric restriction in obese men reduces the conversion rate of testosterone to β-estradiol, increasing the testosterone/β-estradiol ratio from 73.59 to 104.29, which indicates decreased aromatase activity in adipose tissue.

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.

Cause and effect
1 study reviewed
In plain English

When overweight men eat fewer calories, their bodies slow down the process that turns testosterone into estrogen. This means they have more testosterone relative to estrogen, showing that fat tissue isn't making as much estrogen as before.
