I agree with all of this except that “weight loss come down to a simple calorie deficit”. Gary Taubes debunks this pretty convincingly in Good Calories, Bad Calories - worth a read

Taubes is wrong. Is there nuance, yes. But the law of conservation of energy is not theoretical. His argument is. He selectively quoted a meta-study and left out key details. He is an author trying to sell books.
As a general rule, don’t take diet advice from someone who looks like a melted candle.
Law of conservation of energy only applies the closed systems. The human body is not a closed system.
🙄 You can’t debunk something by writing about it in a book. You have to debunk through proven experimentation.
Show me the proof that you got lean while eating in a caloric surplus. If you did, you’d have a Nobel Prize and a thousand coaching clients.
