You spend all your spare time playing basketball, but it takes time and perseverance. It always takes three to six months to change significantly. You get up early in the morning, play in the afternoon and play after self-study in the evening. This is full-body exercise, which is more balanced and the effect will be more obvious. I have a friend who was as tall and as heavy as you when he was a sophomore. You also don't expect to take medicine, which is at the expense of wasting your health potential, and it will rebound and won't be effective. You said that you will get fat above the navel, probably because you eat too much and your stomach is swollen, or because you sleep after eating and accumulate fat. If you drink water and soup, you must eat less before meals. Don't drink soup or water after meals, or your stomach will get bigger. Thighs and hips are fat, so be sure to sit less, especially standing for at least half an hour after meals. The more you sit, the bigger your PP will be.
