Exercise makes it harder to lose weight
Although exercise is good for your overall health, it’s not necessarily helpful if you’re trying to lose weight. Time Magazine:
The basic problem is that while it’s true that exercise burns calories and that you must burn calories to lose weight, exercise has another effect: it can stimulate hunger. That causes us to eat more, which in turn can negate the weight-loss benefits we just accrued. Exercise, in other words, isn’t necessarily helping us lose weight. It may even be making it harder.
It’s all about the compensation problem. Seems like portion control and more healthful eating are the key to weight loss.
