The Claim
In overweight or obese men aged 67 with early-stage prostate cancer on active surveillance, changes in physical activity do not mediate the effect of a weight loss intervention on body composition, indicating that caloric restriction is the primary driver of fat loss and lean mass preservation.
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 overweight or obese men aged 67 with early-stage prostate cancer on active surveillance, weight loss from reduced calorie intake leads to fat loss and preservation of lean mass regardless of changes in physical activity.
See the scientific wording
In overweight or obese men aged 67 with early-stage prostate cancer on active surveillance, changes in physical activity do not mediate the effect of a weight loss intervention on body composition, suggesting that caloric restriction is the primary driver of fat loss and lean mass preservation.
When fewer calories are consumed, the body breaks down fat stores for energy while protecting muscle tissue from being broken down, so fat decreases but muscle stays the same.
What the research says
1 studyIn older men with prostate cancer who lost weight, most of what they lost was fat, and their muscle stayed about the same—even though they also exercised. This suggests that eating fewer calories, not working out, was the main reason they lost fat and kept their muscle.
