How much food is the calorie of 2000 calories?

Calorie is an energy unit, which is still widely used in nutrition measurement and fitness manual. The international standard unit of energy is joule. Generally speaking, there are two kinds of calories:

Calories, also known as the capital letter C, are most commonly used in food labels, which is equivalent to the heat required to raise 1 000 grams of water from 14.5 degrees Celsius to 15.5 degrees Celsius at1atmospheric pressure, which is about equal to the internal energy of 4 186 joules.

Small card, also known as cal, is common in scientific research literature, 1000 small card = 1 big card.

Calories and basal metabolic consumption

Generally speaking, adults need at least 65,438+0,500 calories a day to maintain their body function, because even if you lie still, your body still needs to be able to maintain body temperature, cardiopulmonary function and brain operation. Basal metabolic consumption varies with individual height, weight, age and gender.

Calories and weight loss

Controlling energy intake and proper exercise are very effective ways to lose weight, and most doctors think it is the healthiest way to lose weight. This mechanism is very simple. When the daily energy intake is not enough to provide the energy consumed by the body, the body will call the sugar and fat stored in it. When fat is broken down and provides energy for the body, the process of losing weight begins. It should be noted that some doctors pointed out that the control of energy intake should be gradual to ensure that the human body can adapt to it for a long time, and the energy intake per day is generally not less than 800 calories, otherwise the human body will make up for the lack of energy intake by reducing its body function, which will usually lead to dizziness and fatigue, and the reduction of basal metabolic consumption will also affect the efficiency of weight loss.

The total calorie intake of a normal person should be 2000 calories a day, and people who exercise can increase it appropriately. The following table lists the daily intake of various ingredients and their calorie ratios: (Among them, each gram of fat contains 9 calories; Each gram of carbohydrate contains 4 calories; Protein contains 4 calories per gram).

Fat is less than 65g, and 585 calories are less than 30%.

Carbohydrate 300g 1200 calories 60%

Protein 47g 188 has 9.4% of heat.

Other 27 calories 2.6%

Control fat intake

Fat is an indispensable part of human body. Fat is divided into saturated fat and unsaturated fat. The problem with saturated fat is that it stimulates the body to increase cholesterol production. Unsaturated fat can only lower cholesterol in the blood. Fat cattle, pork and full-fat dairy products contain more saturated fat; Corn oil, sunflower oil, peanut oil, olive oil and vegetable oil are all unsaturated fats. The daily fat intake recommended by experts is 65g, which is equivalent to a piece of meat the size of a cigarette case.

Supplement the right amount of vitamins.

Vegetables and fruits contain a lot of vitamins and minerals, which are essential to supplement human energy. If you eat 6- 1 1 servings of carbohydrates every day (each serving is equivalent to a piece of bread), then you should eat at least 3-5 servings of vegetables (each serving is equivalent to a pot of lettuce) and 2-4 servings of fruits (each serving is equivalent to a medium-sized apple).

Negative calorie food

Negative calorie foods are foods that require more calories to digest than they actually carry.

The heat brought by these foods is more difficult to be crushed by the body than ordinary foods. In other words, the body needs more calories to extract calories from these foods. This makes these foods have the advantage of naturally consuming fat.

For example, a pie contains 350 calories, which may be digested with only 100 calories. In this way, your body will gain 250 calories of fat.

But if you eat a food with only 65 calories, you need 150 calories to digest it. So, you consume 50 calories when you eat that food.

Many foods are low in calories, delicious and delicious, and have excellent negative calorie characteristics. You don't have to starve to death to lose weight. But to eat a lot of negative calorie food to consume too much fat to make yourself naturally slim.
