The Claim
In adults with obesity and prediabetes, 14 weeks of caloric restriction targeting a 390 kcal/day deficit resulted in a mean weight loss of 2.8 kg and a 6.5% reduction in the fat-to-lean mass ratio, which were greater than the 2.2% reduction in the fat-to-lean mass ratio observed with 1.8 mg/day liraglutide.
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 adults with obesity and prediabetes, a 14-week diet creating a 390 kcal daily deficit led to more weight loss and a greater improvement in body composition (less fat relative to muscle) than daily injections of 1.8 mg liraglutide.
See the scientific wording
In adults with obesity and prediabetes, 14 weeks of caloric restriction targeting a 390 kcal/day deficit resulted in significantly greater weight loss (mean reduction of 2.8 kg compared to liraglutide) and a 6.5% reduction in the fat-to-lean mass ratio, indicating more favorable body composition changes than 1.8 mg/day liraglutide, which produced only a 2.2% reduction in this ratio.
When calories are cut, the body breaks down fat for energy more aggressively while protecting muscle tissue because insulin levels drop and fat-burning signals rise. This shifts energy use from stored sugar to stored fat, leading to more fat loss and less muscle loss.
What the research says
1 studyIn a study of adults with obesity and prediabetes, cutting 390 calories a day for 14 weeks helped people lose more weight and more fat while keeping more muscle than taking the diabetes drug liraglutide.
