I'm carb-dependent but analyze: should I train metabolic flexibility? Map current state: energy crashes without carbs, can't access fat stores. Calculate: if I improved ability to burn fat, would that help overall fat loss? Show me the metabolic flexibility: alternate between high-carb and low-carb days. Give me the flexibility protocol: train body to use both fuel sources. Include: whether metabolic flexibility matters, how to train it, and if being carb-dependent is limiting fat burning.
