Normally, 0.5 g of fat contains 4.5 kilocalories. If you want to lose one kilogram of fat, you must consume 4500 calories. If you consume 500 calories through exercise every day, you will lose 5-65,438+00 kilograms a month.

Everyone is different and needs to be scientifically calculated according to everyone's physical foundation and initial weight. Because everyone has metabolism every day, boys need 1 day 1600 calories, and girls need 1200 calories, so they must have the most basic calorie intake every day to maintain the body's needs.

Extended data

Controlling energy intake and proper exercise are very effective ways to lose weight, and most doctors think it is the healthiest way to lose weight. This mechanism is very simple. When the daily energy intake is not enough to provide the energy consumed by the body, the body will call the sugar and fat stored in it. When fat is broken down and provides energy for the body, the process of losing weight begins.

However, it should be noted that excessive dieting will do harm to the stomach and digestive system. Some doctors pointed out that the control of energy intake should be gradual, so as to ensure that the human body can adapt slowly, and the energy intake per day is generally not less than 800 calories. Otherwise, the human body will make up for the lack of energy intake by reducing the body function, which usually leads to dizziness and fatigue, and the reduction of basal metabolic consumption will also affect the efficiency of weight loss.
