This doesn't fit my observations entirely. I have a friend who runs several miles every morning. He says he does this so he can eat an extra 300-500 calories a day ... which he does. He's thin.
I certainly get that less eating is more effective than exercise but in my head I think as long as you burn more calories than you take in you should lose weight. So if you eat 1800 calories a day, assuming you need 2000 a day, you'll lose weight (-200). If you do some exercise that uses 500 calories and eat 2300 calories you're still at (-200)
FWIW, I agree with your observations, so it’s possible I gave the wrong impression. After learning how to track my intake, it changed my view on exercise, and sometimes I also use exercise as a way to eat more. :)
Like many people I consciously and unconsciously resisted the idea of tracking calories and using calories-in/calories-out (CICO) as my primary tool for both weight loss and exercise. It’s not perfect, as many people here are pointing out. However, it doesn’t need to be perfect, and there are scant alternatives that are demonstrably better. I changed my mind and now I see calorie tracking as a way to be better at both exercise and weight loss. Good exercise training, especially weight lifting, requires eating a bit more than expenditure, and good weight loss requires eating a bit less. Either way, I agree with you that exercise can play a valuable part in weight loss, and I think it has many other physical and mental health benefits.
