Study facts come from the paper. Population match, weight-loss explanation and study tier are our judgments, made against the reference group of healthy normal-weight adults aged 55–75.
A Lancet Diabetes & Endocrinology review of muscle loss with weight-loss drugs. Emphasises that lean-mass loss is real, that its functional consequences are unstudied, and that older adults are at particular risk. Authors have nutrition-industry and Novo Nordisk relationships.
