Exercise to lose weight is persistent, not to lose weight in the early stage, but to shape. Simply put, it is to turn puffiness into normal fat, fluffy meat into tight meat, and even gain weight. The only thing you feel in the early stage is that your mental state is getting better and your waistline is getting smaller. If you just stare at your weight, you will basically have no sense of accomplishment and naturally you will not lose weight successfully. It usually takes a month or two to feel the effect of exercise to lose weight.
