As a response to some of the other commenters, weight loss is a more holistic thing than just number of calories.
Even if we assume a calorie is a calorie, and that what kind of calorie has no effect on how fast your body naturally burns them (and that's debatable), the body response may be such that you naturally exercise more if you eat a diet geared one way or another.
That is, the poster may find that after eating carbs, especially simpler ones, their energy spikes, but they're too full to comfortably exercise. But by the time they'd be comfortable exercising they're too tired, and they simply don't. Whereas with higher fat/protein, they feel less full, and/or maintain energy levels longer, and naturally exercise more. Or whatever.
