  The main thing is if calories eaten == calories burned, then you should maintain a stable weight. Exercise helps in this equation because it raises your metabolism (as well as other benefits), which in turn burns more calories.

    This is correct. But my point is that while exercise is a contributor, it isn't the only factor in weight loss. So for this article to conclude that people need to exercise for an hour a day in order to avoid weight gain without mentioning how much they were eating seems very incomplete.

    There is an additional subtlety that may interest hackers. It is actually if calories metabolized by the body == calories burned. Calories are mostly fungible, but they are processed differently (by the liver or by the cells themselves, for instance) and this has drastic effects on metabolic health. For instance, fructose is processed by the liver and does not trigger the satiety hormones as easily as glucose. So, while the total amount of energy available is the same for calorically similar amounts of fructose and glucose, the impact on fat storage and hunger is different.
