Losing weight on an empty stomach is definitely not desirable! It's really impossible not to eat at all. But if you want to lose weight, you must control your diet and exercise more. In addition, we must persist. I used to lose weight for two months A steamed bun in the morning, a watermelon at noon and a watermelon at night (about 1 kg), aerobic for one hour in the morning, aerobic for one hour in the afternoon and running 3000 meters at night. Other life and work are normal. I have lost weight 15 kg.
