If I'm strict on beef, eggs and butter, I can't gain weight consistently no matter how hard I try to eat and overeat. In fact I end up leaning out. I gave up counting calories over a decade ago and I got into the best shape of my life by only really changing what I was eating.
Must be something more to the equation.
That's an easy one. a carnivore diet like that is satiating, you can't really over eat.
Processed foods aren't as satiating, and you can over eat easily.
If you're not satiated, you're going to continue to eat, thereby consuming more calories. But if you actually control for calories against those 2 diets, you can lose weight on McDonald's, you're just going to be hungry
