About this episode

Dr. Rosy Boa and guest Àngel Casas discuss body liberation, diet culture, and reclaiming agency in fitness.

Dr. Rosy Boa hosts Science of Slink with guest trainer Àngel Casas, who practices body liberation, anti-diet, weight-neutral coaching, with a content warning for eating disorders, religious trauma, body weight, diet culture, and fatphobia. Angel describes being raised in a religious cult with strict body control, later leaving, coming out as a queer man, and repeatedly yo-yo dieting before starting a weight-loss fitness business during COVID. After working with clients and feeling triggered by diet practices, he sought help at an eating disorder center and learned about oppression, capitalism, and how “good body/bad body” narratives connect to diet culture; he shifted into non-diet personal training. Together they discuss weight-loss fitness as a results-based “scam,” problems with BMI and moralizing body size, medical fatphobia, GLP-1 drugs and harm reduction, alternative health markers (embodiment, daily functioning, strength, breath, joy), dismantling authoritarian fitness power dynamics, and building agency and compassion in movement.
