Those advertised weight-loss products are useless. Merchants are all trying to make money, which won't last long and has many side effects. For example, endocrine disorders, hyperactivity, sleep disorders, appetite suppression, trance, constipation, acne and spots and so on.

Eat fewer calories than you consume, plus exercise to lose weight.

Aerobic and anaerobic exercises are interspersed for one hour every day, such as running for 5 minutes+walking 10 minutes. Or dance wildly at home for an hour and dance casually in a way that makes you sweat.
