Losing 7 kg in 3 days is not a normal way to lose weight. I can tell you responsibly that more than 90% of your weight loss is water. If you drink more water every day, your weight will go back and gain weight immediately. You believe in diet pills. You're really being fooled into showing off.

To lose weight, we must do aerobic exercise with diet, and engage in those messy and useless things, which is harmful to our health. Women, in particular, will regret it sooner or later if they don't take care of their bodies.
