> Most people who want to lose weight (aka mostly unfit/untrained) are not going to be able to exercise the amount would take to truly force a calorie deficit.

This is well known and true even if the claims made better happened to be entirely false. I’m not dismissing your point, here. I agree fully.

Exercise just doesn’t burn enough calories to really matter. Especially in the face of a poor diet. Running burns ~100 calories per mile (yes, varying based on weight and a little bit based on speed but it’s a close enough rule). A can of soda has ~150 calories. There’s just no competition. Someone trying to lose weight can skip a soda or a candy bar and it’s more effective than running an extra mile.
