Adults need different calories every day according to gender. Adult men need about 65,438+0,800 calories a day, and women need about 65,438+0,500 calories a day. This is because even if you lie still, your body still needs energy to maintain body temperature, cardiopulmonary function and brain operation.
A person's daily calories need to be determined according to his height, weight, health and physical activity. Generally speaking, for healthy adults engaged in light manual labor, the daily calorie requirement is the standard weight (standard weight = height-105cm) multiplied by 30-35 kilocalories, for example, a healthy adult female engaged in light manual labor weighs 60kg.
The daily heat requirement is about 1800 to 2 100 calories. For obese people, the calorie intake should be reduced appropriately, and for thin people, the calorie intake can be increased appropriately. People with three highs should be cautious.
Matters needing attention in daily calorie intake of normal people:
A person's basal metabolic rate at rest is generally 1400 to 1800 calories for men and 1000 to 1400 calories for women, which will fluctuate according to age, height and weight. In addition, daily activities will also consume some, so as to maintain normal metabolism. These calories can supplement the energy consumed by the human body after being ingested into the human body.
When a large amount of intake is much greater than discharge, these calories will accumulate in the body and become fat, thus forming obesity. When inhaled and consumed in large quantities, these calories are converted into cholesterol in the body, which will cause high blood pressure and hyperlipidemia, which is not conducive to health. Therefore, it is recommended to eat more low-calorie foods.
Due to the accelerated pace of life, reduced human activities and unhealthy lifestyles, more and more people have diseases with excessive calorie intake, resulting in metabolic syndrome such as hypertension, hyperglycemia and hyperlipidemia.
