You can convert that fat to muscle with hard work. Its actually difficult for a lot of people to put on size and weight. You already have it. You just need to build it back up as muscle instead of fat. But people that go to the gym get frustrated when they don’t see results after a month. If you stay consistent with a full body lifting program and you stay in small calorie deficit you will see fantastic results at the 3-5 month range. And good diet enhances this progress. Cut out the s***** carbs. Eat a lot more protein. 0.8g per 1 pound of body weight.
The most important thing is to never starve yourself. If you want to lose weight. You need to eat more not less. Eat more and more often. But make better eating choices. You can absolutely eat takeout a couple times a week and drink if you maintain a healthy diet. Its actually good for your body and your mind to throw it curveballs. Had to fit in a Baseball reference lol.
