If you are reporting everything correctly as per your diet and exercise calendar then you should
be losing weight. Is it possible that you are under reporting your food intake and/or overestimating your exercise intensity?
Barring that, the only other thing I can surmise is perhaps you are over training. You could try scaling back a bit on the exercise and see where that takes you. Or try eating a bit more protein to support your muscle building efforts. It is sometimes easier to think there is something wrong with our body when it's really just simple mechanics and math that we are miscalculating.
Outside of that, you could consult with a doctor to rule out any medical issues.
But hang in there and keep tweaking and trying different things. It's usually the simplest explanation, something we've overlooked, that solves the puzzle.
IT NEVER GETS EASIER - YOU JUST GET BETTER.
