What should I do if the meat is loose after losing weight? Besides sports?

Losing weight too fast, consuming fat and water too fast, and skin contraction can't keep up with the rhythm, so there will be relaxation, which is a normal phenomenon after losing weight quickly. Don't worry, keep exercising and you will soon adjust. Sticking to scrubbing with cold water can accelerate skin contraction and increase skin elasticity.

Eat some foods rich in collagen in the skin (trotters, chicken feet, etc.). Restore skin elasticity.
