Precautions for heat required by human body:
1, just like computers consume electricity, cars consume oil and people consume heat. Heat is an indispensable fuel for human body, which is needed for our daily work and life, blood circulation, breathing, digestion and absorption. Even if we lie still, our bodies still need heat to maintain body temperature, cardiopulmonary function and brain operation.
2. The consequences of long-term insufficient calorie intake are worrying, especially for people who consume less than 800 calories a day. After three or four months, it will become weak and weak, and symptoms such as diarrhea and constipation will appear, which will also affect the salt and cholesterol content in bile and cause gallstones.
All the calories needed by human body come from food. Carbohydrate, fat and protein are the main sources of calories. Each gram of carbohydrate and protein can provide 4 calories for human body, and each gram of fat can produce 9 calories.
Many people who want to lose weight stay away from the high temperature. They think that if you want to lose weight successfully, you have to control your calorie intake, so foods that can produce a lot of calories become "street rats", especially carbohydrates and fats. Some people argue that carbohydrates can make people fat. Don't eat carbohydrates to lose weight.
Extended data:
High calorie food:
1, all foods with high fat, high sugar and high calorie are high calorie foods, which usually refer to foods with high fat content after frying, frying, roasting and frying, including all animal and vegetable oils, fatty nuts and processed foods.
2. Fat is a high-calorie food and one of the three major sources of calories, so some people put forward an oil-free diet. Rejecting fat may help to lose weight, but it is not desirable. Vitamins A, D, E and K, which are needed to maintain human hormone levels and cell operation, are fat-soluble vitamins, which are insoluble in water and soluble in fat and organic solvents. Everyone needs fat to be absorbed by the body.
3, some fatty acids are needed to maintain the operation of the body, and too few fatty acids can not function normally. So even fat people or people who want to lose weight can't put high-calorie foods such as cooking oil on the shelves. It is wise to choose healthy edible oils, such as olive oil, linseed oil and sunflower seed oil.
