How many calories does the human body consume in a day?

Nowadays, many people think that they can lose weight by not eating, but this is actually a very wrong idea, because the human body must consume a certain amount of calories a day. If you don’t eat, it is very likely that your body will be overdrawn. This will not only not make you lose weight, but will also cause great harm to your body. So you must understand this knowledge so that you can have a new understanding of your body.

Daily calories needed for adults: Male: 9250-10090 kJ Female: 7980-8820 kJ

The energy needed by the human body comes from three substances: carbohydrates, fats and proteins. Vitamins and minerals have no energy. So calories come from carbohydrates, protein and fat.

Carbohydrates and proteins can release 4 kcal of energy per gram, and fat can release 9 kcal of energy per gram. So eating more fat can make you fat.

Of the energy we take in from food, 60% to 75% is consumed by basic metabolism such as breathing, blood circulation, and cell renewal. Another 10% is used for digestion, and 20% to 30% is consumed by exercise.

If you exercise normally, you can get the number of calories you should consume every day by multiplying your weight in pounds by 11. Studies show that women who consume fewer calories than this standard will have their metabolic rates reduced by 45%.

There is no uniform standard for calorie intake. It should be calculated based on each person's weight and activity level. The amount of calories required by the human body varies from person to person, and the factors that affect it are mainly labor intensity, age, climate change, body shape, weight and health status.

According to the book "Calorie and Protein Intake" published by the World Health Organization, a healthy adult woman needs to consume 1800 to 1900 calories per day, while a man needs 1980 to 2340 calories.

Among them, protein intake should be 10% to 15% of the daily calorie requirement of the human body; carbohydrate intake should not be less than 55% of the daily calorie requirement of the human body; fat intake should not exceed 30% of the daily calorie requirement. In addition, daily salt intake should not exceed 6 grams, and daily dietary fiber intake should be no less than 16 grams.

Once you understand how many calories the human body consumes in a day, you will not dare to skip meals. If you want to lose weight by dieting, you must eat these calories before stopping. This will ensure that the calories in your body are enough for you to consume. It is also very helpful for your body. Moreover, skipping meals frequently may cause anorexia.
