    Changes in Trunk, but Not Limb, Lean Body Mass Contribute to Variability in Metabolic Adaptation Following Weight Loss by C. Martins, B. A. Gower, G. R. Hunter

    Published 2025-04-01
    “…ABSTRACT Background Metabolic adaptation (MA) in response to weight loss is highly variable. Several methodological issues are likely to contribute to the large inter‐individual variability in MA, namely the lack of adjustment for changes in the composition of fat‐free mass. …”
