I've dieted for years but analyze: have I damaged my metabolism? Map diet history: how many diets, how aggressive, how long each. Calculate: if I've done metabolic damage from yo-yo dieting, what's the recovery protocol? Show me the metabolic repair: reverse dieting, maintenance phases, slow approach. Give me the recovery plan: heal metabolism over this timeline. Include: whether diet history has slowed metabolism, how to repair damage, and if I need to maintain before cutting again.
