How much food should a normal person eat at least a day?

A total intake of 1700 kilocalories a day is enough, which is equivalent to about 5 ounces of rice, about half a catty of meat, and about a catty of vegetables and fruits. But people in different occupations have some differences in total calories. Specifically, they are engaged in low physical activity: standard weight × 30 = required calories (kilocalories); Engaged in moderate-intensity physical activity: standard weight × (35 ~ 40) = required calories (kilocalories); Engaged in heavy physical activity: standard weight × (45 ~ 60) = required calories (kilocalories).

In addition, if the food calories below 1000 calories per day are maintained for a long time, human cells will become cancer cells due to long-term malnutrition, leading to the unfortunate end of cancer decades later, which most people did not expect. Chronic malnutrition is one of the main causes of cancer.

Because some people often use unhealthy diet products or diets, their metabolic level may be lower than that of ordinary people, that is, they don't need to consume so many calories to maintain their current weight, so please don't use unhealthy weight loss methods casually.

Extended data:

The food the human body needs in a day is at least:

Vegetables: hold or put?

Hands together, one can hold up the amount, that is, one. Holding it in both hands can be used to measure the amount of vegetables, which is the amount of vegetables washed and cut into pieces. The amount of food held by one hand is about100g.

Soybeans and nuts: hold them in one hand

The action of holding with one hand is the amount that five fingers can bend and the palm can pick up. This measurement method is more suitable for simply measuring the amount of granular foods such as soybeans and nuts. The amount of peanuts or soybeans in one hand is about 20 grams. If it is a nut with a shell, it should be shelled and weighed.

Spherical and lumpy food: fist

Spherical and lumpy foods are common in staple foods, such as a round steamed bun or a piece of sweet potato. An adult trumpeter's fist-sized steamed bread weighs about 80 grams.

Meat, cheese, etc. : two fingers are thick and long.

For ordinary meat or cheese, it can also be measured by the thickness and length of the index finger and middle finger.
