I had very similar experience. I lost weight with no much additional effort when I started to do a lot sport. I did not focused on food much, I was doing sport for weight loss unrelated reasons. And it dropped.

Attempts to loose weight by diet only all failed. To make it worst, there is also aspect of most common diet advice being plain wrong. It focuses on calories too much. It completely ignores what your body needs, so you end up in nutritional deficiency - this kind or that kind. And that will affect a lot and eventually you will stop diet and start to feel so much better and healthier after stopping it.
