Some people will retort: I sweat and lose weight after every exercise. Why sweating is not equal to losing weight? Indeed, if you sweat more, you will lose weight. But it is the water in the body that falls, not the fat. If you eat and drink a little, your weight will return to its original level.

Fat is the heat stored in the body. The only way to make it disappear is to raise your heart rate through aerobic exercise and keep you in a state of insufficient calories. It's not how much you sweat.
