That's basically my stance, here. Calories in/calories out is perfect. What is flawed is the method of calculating one's calories because you may have a rare condition that causes your metabolic rate to be extremely slow.

In the rare case with someone with hypothyroidism or some severe metabolic genetic disorder, they may have such a slow metabolism that a calculator that puts them at a TDEE of 1,900 where they're really at 1,200 just for maintenance...well, there's a big issue there. But that's not a flaw in calorie theory. It's a flaw in the method of calculation. Perhaps SAD foods are destroying your thyroid and testosterone and eating primally fixes them - then there is a legitimate example where you can eat more primal foods. However, the calorie theory still holds - your recovered thyroid just increased your metabolic rate, leading to a higher TDEE. Anyone with a somewhat properly functioning metabolism - which is almost all of us - weight loss is going to come out the same if calories and macros are the same regardless of food choices.
