The Claim

In adults with obesity and prediabetes, caloric restriction preserves lean mass during weight loss, whereas liraglutide treatment is associated with a significant reduction in lean tissue, indicating differential effects on body composition.

In plain English

In adults with obesity and prediabetes, losing weight through calorie reduction maintains muscle mass, while taking liraglutide leads to a measurable loss of muscle mass.

See the scientific wording

In adults with obesity and prediabetes, caloric restriction preserved lean mass during weight loss, while liraglutide was associated with a significant loss of lean tissue, suggesting differential effects on body composition that may influence long-term metabolic health.

Why this might work

When a hormone that signals fullness binds to receptors in the brain and muscles, it tells the body to hold onto muscle and burn fat instead, even when eating less. This keeps muscle mass from breaking down while fat stores shrink.

    When people lost weight by eating less, they lost more muscle relative to fat than those taking liraglutide — the opposite of what the claim says. Liraglutide actually helped preserve more muscle compared to dieting alone.
