One thousand calories is roughly equivalent to 0. 1 1g fat burning, which is 0.00022kg fat. Each kilogram of fat contains about 7700 kilocalories. However, if you want to calculate how much body fat is consumed in reverse, you can't simply convert it.

Because the calorie intake of 1000 calories should be considered when it acts on the human body, only the difference between the calorie intake and the calorie consumption, that is, the calorie difference, can really produce the effect of losing weight, so 1000 calories may be consumed, but the fat equivalent to these calories will not be consumed.

Lipid is the general name of oil, fat and fat. Oily substances in food are mainly oil. Generally, liquid at room temperature is called oil, and solid at room temperature is called fat. Fat is composed of three elements: C, H and O. Fat is a triglyceride composed of glycerol and fatty acids, in which the molecule of glycerol is relatively simple, but the types and lengths of fatty acids are different.

Fatty acids are divided into three categories: saturated fatty acids, monounsaturated fatty acids and polyunsaturated fatty acids. Fat is soluble in most organic solvents, but insoluble in water. It is the glyceride C3H5(OOCR) of one or more fatty acids.
