Eating and exercising are not impossible!
Eat more high-protein and low-fat foods in your diet. It's good to eat some protein powder if you can. Don't miss it! ! ! You can eat less, but you must have a balanced nutrition.
In sports, running is a very unbalanced sport. I think of course there are many other exercises. If you are reducing fat, you can do more exercise, but you must remember to stretch and stretch! ! ! And massage is also very effective.
