try out my earlier comment "Try Calculating your TDEE (at sedentary) and eating 500 calories (accurately) below it for 12 weeks and come back, you'll weigh 12lbs less. I don't think that's a red herring."
The very nature of counting calories is an accounting of persistently causing more calories to be expended than intaken. Your post appears delusional. Calorie deficits cause weight loss and "report them".
That video you linked is focusing more on "health" than "weight loss", which should be considered different. If there's somewhere in that 1:40:00 long video that he says calorie counting doesn't work, please time-stamp it.
is the difference more than 5% - 10%? because there are differences between the efficiency of energy consumed during digestion of the different macros (Fat, Protein, Carbs). That could be the obvious difference here. Otherwise, it's not a red herring.
For example, I've heard that if 100 calories is eaten of protein, you may only digest 80 calories, arbitrary number, but it may differ than carbohydrate's 90 calories per 100 eaten.
Try Calculating your TDEE (at sedentary) and eating 500 calories (accurately) below it for 12 weeks and come back, you'll weigh 12lbs less. I don't think that's a red herring.
Is this article implying calorie deficits are not what cause weight loss? Or am I misunderstanding? He links to the idea that "we don't know what causes weight loss", but studies show calorie deficits do.
