Rethinking Body Composition In Professional Football: From Risk To Responsibility

Over the last decade, I’ve seen first-hand how body mass and composition monitoring has become routine in elite football. Done well, it supports fuelling, development, and rehabilitation. Done poorly, it fuels anxiety, disordered eating, and a culture where appearance outweighs performance. Recent headlines from Fran Kirby, Alessia Russo, Kalvin Phillips, and Allan Saint-Maximin show body-shaming persists across men’s and women’s football. Similar issues are seen in cycling and cricket, with “fat clubs” still an open secret. Too often, arbitrary percentage targets—without scientific basis—drive harmful behaviours, from extreme low-carb diets to players skipping meals just to “hit green.” As practitioners, we must ask: what does the science actually tell us, and how can we build safer, evidence-based systems?
