Welcome to HCM.
You seem to be over straining your self in trying to maintain a good figure. To a certain level it is acceptable but beyond that it could do you more harm than good.
Best is to learn to adjust to our body and live with it.
If you are still concerned about your sagging protuberant belly, laser treatment
seems to be more promising.
Personally I feel you should not over do it.
Wish you all the best.
