Obesity is because the energy intake is greater than the energy consumption, and the excess energy is converted into fat and deposited in the body. Therefore, to lose weight, we should start with reducing energy intake and increasing energy consumption. Drinking salt water on an empty stomach in the morning has no effect on reducing energy intake and increasing energy consumption.

The scientific way to lose weight is to control diet reasonably and combine with moderate exercise. The principle of diet control is to control the total food intake. Breakfast is full at 9 o'clock, lunch at 7 o'clock and dinner at 8 o'clock. Eat less high-energy foods such as greasy food, sweets and snacks, eat more fresh fruits and vegetables and coarse grains, and chew slowly. Aerobic exercise, swimming, jogging, brisk walking, at least half an hour every day, at least five times a week.
