Body Composition

Adjusted fat mass decreased with semaglutide and increased with placebo. Fat loss can improve health for people with obesity, but the method matters. The MRI results were reported as ideal across all measured regions. Preserving muscle is connected to later-life mobility, independence, and physical engagement with life. Body composition is considered more informative than scale weight or BMI. The article rejects the idea that weight loss automatically equals health in all contexts. Semaglutide-associated weight loss was largely driven by fat mass reduction. Protein supports body composition improvement through lean tissue support, satiety, and high metabolic cost. The proportional lean soft tissue mass pattern suggests fat mass accounted for most total weight reduction. BMI is criticized because it does not distinguish fat from muscle or indicate metabolic condition. Lean soft tissue mass declined more in absolute terms with semaglutide than with placebo. Losing muscle and pursuing unsustainable low-protein restriction are framed as harmful. Protein is presented as essential for high-quality weight loss. A whole-body MRI was used to document muscle and fat distribution across the…
