They don't understand this and probably never will. The human body is incredibly energy efficient. A straight 60 minutes of vigorous, intense cardio (rowing, cycling, running, etc) will burn 600-800 calories for most people in decent shape. That's a large beetus from McDonald's and you know fatfucks will reward themselves with like 3 of them too. Of course the idea of a ham working out for 60 minutes is laughable; even with the insanely higher tdee just from being a fatass, they may burn like 200-300 cal waddling in a treadmill at best. Exercise is 100% THE BEST thing you can do for your body for so many reasons but calorie burning is not one of them and never has been.
