Calories, and insulin is mostly a passenger

Insulin and cellular signalling, not arithmetic
Norton is describing weight regulation in a general adult population under controlled conditions. Insulin-forward advocates are typically describing people with existing insulin resistance or metabolic syndrome, where the populations and the outcomes genuinely differ.
Norton's written concession is the agreement: intake and expenditure are not independent, hormones do influence both, and metabolic adaptation is real and substantial. His ln-ep31 (6 Jul 2026) is seventy-six minutes on exactly that. The dispute is about whether hormonal effects operate through energy balance or around it, not about whether they exist.
Norton would move on isocaloric feeding trials with matched protein showing a reproducible difference in fat loss by carbohydrate content. He has said which study design would answer it, which is a rare and citable thing.
