A food calorimeter is a list drawn or listed according to the energy contained in a unit amount of food (for example, 100g) for reference in diet and health care. Different foods produce different energy. For patients with obesity, diabetes, hypertension and other chronic diseases, controlling the body's energy intake every day is a way to alleviate their own diseases. Therefore, it is necessary to measure the energy contained in each food for patients to calculate or arrange the total energy contained in each meal.
The calories a normal person needs every day are related to his weight. The relationship between calorie intake per hour and body weight is about 1 kcal/hour/kg, that is, 4. 186 kj/hour/kg. Therefore, the normal average daily calories required by an adult weighing 50 kg are as follows:
Average required heat? = 4. 186 kJ？ * 24 hours * 50kg = 5023.2kJ
On average, for every kilogram of weight gain, the calories required by human body will increase by 0. 1MJ. Generally speaking, an adult man needs about 9.25 to10900 joules every day; An adult woman needs about 7.98 to 8.82 million joules a day. Pupils need about 9.25 million joules of heat every day on average, which is similar to the minimum heat required by an adult man. Middle school students are developing and need to consume more calories. Boys need 10.465 MJ on average every day, while girls need 10.046 MJ.
