I disagree with that conclusion.

Humans are surprisingly efficient at minimizing calories spent on exercise. Exercise is great to optimize other systems in the body, but it shouldn't be used as the primary method of losing weight. Calories In Calories Out is the golden rule when it comes to changing weight (either up or down). To lose weight, I recommend intermittent fasting and consuming less empty calories.

I agree with you that exercise is a poor way to lose weight, unless you are excessive about it. But I think it is true that high intensity exercise (e.g., intervals on the track) leads to weight loss better than, say, long slow distance.
