The Claim

In adults with type 2 diabetes and obesity (BMI 28–40), monthly intravenous administration of bimagrumab (10 mg/kg) for 48 weeks causes a 20.5% reduction in total body fat mass, a 3.6% increase in lean mass, and a net 6.5% decrease in body weight.

In plain English

See the scientific wording

In adults with type 2 diabetes and obesity (BMI 28–40), monthly intravenous bimagrumab (10 mg/kg) for 48 weeks causes a 20.5% reduction in total body fat mass and a 3.6% increase in lean mass, with a net 6.5% decrease in body weight, demonstrating a unique pharmacologic effect of simultaneously reducing adiposity while increasing muscle mass.

Why this might work

A drug blocks a signal that normally stops muscle growth, so muscles get bigger. At the same time, fat tissue starts burning more energy, so fat decreases. The body loses weight because it gains muscle and loses fat at the same time.

  1. Study: Effect of Bimagrumab vs Placebo on Body Fat Mass Among Adults With Type 2 Diabetes and Obesity

    In a well-run study, people with type 2 diabetes and obesity who got monthly bimagrumab shots lost 20% of their body fat, gained 3.6% more muscle, and lost 6.5% of their total weight — all without changing their diet or exercise much. The study proves the drug does exactly what the claim says.
