Claims supported
- Sustained fat loss requires net energy deficit, but the appetite, expenditure, adaptation, and maintenance systems that shape that deficit are biologically regulated.
- Calories describe the accounting of tissue-energy change, but they do not explain all biological friction around appetite, expenditure, adaptation, food environment, hormones, sleep, lean mass, and maintenance.
- Large weight loss can reduce resting energy expenditure beyond what body-size change alone predicts, illustrating that calories-out is adaptive rather than fixed.
- Insulin and carbohydrate quality matter, but controlled feeding evidence does not support a simple insulin-only explanation of obesity or fat loss.
