How many calories does an adult need for breakfast?

An adult needs about 1,700 kcal a day, and breakfast accounts for 30% of the calories throughout the day, which is about 500 kcal.

An adult who does not exercise under the condition of normal activities a day, he walks normally and thinks normally every day, and consumes about 1500 2000 kcal of energy every day, while a normal person eats three meals a day and consumes about the same amount of energy, just in such a total The energy of the body is balanced.

If you have the habit of exercising, and you can spare an hour a day to exercise, then this hour can at least consume 400 500 kcal of energy, that is, you can consume a meal, but if you keep exercising, you can't exercise for 5 minutes and rest for half an hour, in this case, there is no burning effect.

So if you want to **, you have to control your energy intake, reduce one meal, and then you add another hour of exercise, and it will have an effect if you stick to it, and it may not be particularly obvious in the short term, but you have to be able to stick to it for a month, and the weight will gradually go down in two months.

An adult needs about 5,000 calories a day, and only in this way can it exercise properly.

It takes about 1500 to 1800 kilojoules of heat a day. However, it may increase or decrease depending on each person's situation.

The specific value depends on your height and weight, and one admission is about 1500 calories.

Male : 9250- 10090 kJ; Female: 7980 - 8820 kJ.

Note: The daily calorie supply from food should be no less than 5000 kJ - 7500 kJ This is the minimum amount of energy required to maintain the normal life activities of the human body.

Calories come from carbohydrates, fats, proteins. Carbohydrates produce calories = 4 kcal grams, protein produces calories = 4 kcal grams, and fat produces calories = 9 kcal grams.

Calorie unit: kilocalorie, kilojoule, 1 kcal = kilojoule, 1 kcal: is the amount of heat that can make 1 ml of water rise by 1 degree Celsius.

The relationship between heat and internal energy is like the relationship between work done and mechanical energy. Heat is a measure of the amount of energy that can change within an object. If thermal equilibrium has not yet been reached between the two regions, then heat is transferred from the hot place in the middle to the lower one.

Any substance has a certain amount of internal energy, which is related to the disordered movement of the atoms and molecules that make up the substance. When two substances of different temperatures are in thermal contact, they exchange internal energy until the temperature of the two bodies is the same, that is, thermal equilibrium is reached. The amount of energy transferred is equal to the amount of heat exchanged.

An adult needs about 12,000 calories a day.

This has something to do with the age of the person, when he was young, the metabolism was naturally perfect, and the spontaneous combustion of this car was needed, and there was a relationship between fat and thin, the fat body surface area is large, and the quality required is naturally more, which does not have a prescribed range, which is a relatively fixed answer.

A healthy adult woman needs to consume 1,800 to 1,900 calories per day.

Men needed 1980 2,340 calories. Among them, protein intake should be 10 15 of the daily caloric requirements of the human body; Carbohydrates.

The daily caloric intake should not be less than 55 of the daily caloric requirement;

It should be noted that the control of calorie intake should be gradual to ensure that the human body can adapt to it over time, and the daily calorie intake should generally be no less than 800 kcal.

Otherwise, the body will compensate for the lack of energy intake by reducing bodily functions, which usually causes dizziness.

Fatigue condition, but also basal metabolism.

The reduction of consumption also affects the efficiency of **.

A breakfast of 400-600 calories is preferable.

The amount of breakfast you eat varies depending on your body type and age, but the calorie intake of 400-600 calories is moderate, accounting for about a quarter of your daily needs.

Calories are the energy that the body consumes all the time, and these energies are provided by the heat-producing nutrients in food. The calorie-producing nutrients in food are proteins, fats, sugars, and carbohydrates. Oxidation produces heat for the body to sustain life, growth and movement.

When there is too much heat, the excess heat is stored as fat.
