I agree that focusing on input has far higher returns than focusing on output. Simple calorie comparison predicts it, and in my personal experience I’ve noted small appearance and weight changes after changes in exercise level and large appearance and weight changes after changes in intake level. That said, the traditional view- “eat less and exercise more”- has the direction of causation mostly right for both interventions and to represent it as just “exercise more” seems mistaken.
