1 g fat =9 calories

100 kcal =100/9 =11.1g

100 kcal = 1 1. 1 kg (i.e. 22 kg)

Normal weight loss is to metabolize fat, so if you calculate according to fat, you need to metabolize 7700 kcal of fat to lose one kilogram of weight. In proportion, 100 kcal of heat is equivalent to about 26 grams of weight. Therefore, if you lose weight quickly, it is suggested that you need to consume150g of fat through exercise every day, and you need to consume about 600 kilocalories, which 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 just pure exercise consumption. If the fat intake is greater than the amount of exercise consumed, you can't lose weight, so you should pay attention to the fact that you can't consume too much energy. The energy that the human body must consume every day is about 1800 calories.

Generally speaking, adults need at least1500 ~ 2000 calories a day to maintain their body functions, because even if you lie still, your body still needs energy to maintain body temperature, cardiopulmonary function and brain operation. Basal metabolic consumption will be different due to the differences of individual height, weight, age and gender. Human beings need energy to survive and get it from food.
