The Claim
In overweight or obese adults, a 12-week intervention combining once-weekly semaglutide (escalated to 2.0 mg) with lifestyle counseling is associated with a mean body weight reduction of 6.77 kg (SD 4.85), composed of 4.75 kg (70.2%) fat mass loss and 2.02 kg (29.8%) muscle mass loss, and a concurrent increase in muscle-to-fat ratio by 0.15 (from 1.37 to 1.52).
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 adults, taking semaglutide once a week along with lifestyle counseling for 12 weeks is associated with an average weight loss of 6.77 kg. This weight loss consists of 4.75 kg of fat loss and 2.02 kg of muscle loss, and the muscle-to-fat ratio increases by 0.15.

Semaglutide tells the brain to eat less and signals fat cells to release stored fat. The body then burns more fat than muscle, especially belly fat, so overall body composition improves. Some muscle loss happens, especially in less-used muscles, but the ratio of muscle to fat goes up.
What the research says
1 studyStudy: Effects of once-weekly semaglutide on regional body composition in overweight or obese adults
The study found that using semaglutide once a week plus diet and exercise advice for 12 weeks led to an average weight loss of about 6.8 kg, mostly from fat, matching what the claim says.
