Joule, calorie, calorie, kilocalorie and kilojoule, which we often see every day, are all units of heat measurement, and the conversion relationship between them is as follows:

1 card =4. 186 joules

1 kcal = 1 kcal = 1000 kcal = 1000 calories =4 186 joules =4. 186 kj.

1 kj =0.23889 kcal

The heat of each food is determined by measuring the heat released by its complete combustion in the laboratory. The picture below shows the calories of common foods. Foods with bags in the supermarket will be labeled with calories.

Because everyone's metabolic rate is different, in the case of staying still all day, under normal circumstances, adult men consume 1500- 1800 calories, and adult women consume 1200- 1600 calories. If you exercise, the calories you burn will increase every day. During fat reduction, you can lose weight by controlling the difference between intake and consumption of calories. It is suggested that the daily heat difference should be controlled at about 300 calories, with a maximum of 500 calories.
