Calorie is defined as the heat required to raise 1 gram of water 1 degree Celsius at 1 atmospheric pressure; Calories are units for calculating calories, which can be divided into large calories and small calories. 1 kcal is equivalent to the heat used to raise 1 liter of water 1 degree Celsius at 1 standard atmospheric pressure; 1 kcal equals 1000 kcal.
The conversion relationship is:
1, 1 calories = 1 calories =4. 184 joules;
2. 1 kcal = 1 kcal = 1000 kcal = 1000 calories =4 184 joules =4. 184 kj.
3, 235 kcal =235 kcal.

Calories and weight loss:
Controlling calorie intake and proper exercise is a very effective way to lose weight, which is regarded by most doctors as the healthiest way to lose weight. If the daily energy intake is not enough to provide the energy consumption of the body, the body will call the sugar and fat stored in it. When the fat is broken down and provides energy for the body, the weight loss process begins.
It should be noted that the doctor pointed out that the control of calorie intake should be gradual, so as to ensure that the human body can adapt to it for a long time. At the same time, the calorie 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 its body function, which will usually lead to dizziness and fatigue, and the reduction of basal metabolic consumption will also affect the efficiency of weight loss. The total calorie intake of a normal person should be 2000 calories a day.
Calories and KJ (kilojoules) are both units of heat. The calorie is written with the letter C, which is the most commonly used calorie unit in nutrition and is most commonly used in food labeling. The SI derived unit of heat and the legal unit of measurement in China are joules. Other units of heat are calories and kilocalories.
A simple algorithm for the basic calorie of human body's basic metabolism;
1, female: basic calories (calories) = weight (kg) x 9
2. Men: Basic calories (calories) = body weight (kg) x 10
