1 g fat =9 calories
100 kcal =100/9 =11.1g
100 kcal =11.1kg (i.e. 22kg).
Normal weight loss is to metabolize fat, so if you calculate according to fat, you need to metabolize 7700 calories to lose one kilogram. In proportion, 100 calories is equivalent to about 26 grams of body weight. So if you lose weight quickly, it is suggested that you need to consume150g of fat through exercise every day, which is about 600kcal. It is only a rough calculation and is influenced by many factors.
Extended data:
One kilogram of fat =7700 calories. You can consume almost one kilogram of fat in 20 days, which is only pure exercise consumption. If the intake of fat is greater than the amount of exercise consumed, you can't lose weight, so pay attention to the intake of energy. The energy that the human body must consume every day is about 1800 calories.
Generally speaking, adults need at least1500 ~ 2,000 calories a day to maintain body function, because even if you lie still, your body still needs energy to maintain body temperature, cardiopulmonary function and brain operation. Basal metabolic consumption varies with individual height, weight, age and gender. Human survival needs energy, which is obtained from food.
