How many calories does a person need to consume every day?

The human body consumes energy all the time, and energy is provided by thermogenic nutrients in food. In 2000, China Nutrition Society put forward the reference intake of dietary energy for China residents, pointing out that adult male light and moderate manual workers need 2400-2700 calories a day; The daily energy requirement of female light and moderate manual workers is 2 100-2300 kcal. Babies, children and adolescents, pregnant women, nursing mothers and the elderly have different physiological characteristics and different energy requirements.

Reference: Daily calories required by adults (1 calorie = 4. 184 kJ)

Male: 9250- 10090 kJ?

Female: 7980-8820 kJ?

Note: The daily calories provided by food should not be less than 5,000-7,500 kilojoules, which is the least energy to maintain normal life activities.

In other words, you should be healthy and consume at least 1200 calories every day.

People consume at least three calories a day.

Basic heat required for basic metabolism of human body+heat required for physical activity+heat required for food digestion. ?

Simple algorithm of basal metabolism =?

Female: Basic calories (kilocalories) = weight (kilograms) x 9?

Man: Basic calories (kilocalories) = weight (kilograms) x 10?

Physical activity algorithm = weight (kg) * activity intensity coefficient * hours.
