How much should a twelve year old eat in a day

Answer: When a 12-year-old child is growing up, you can cook more meat for him, and at the same time let him eat some fruits and vegetables.

Multigrain, pay attention to let him exercise more, it will grow very strong, very tall.

There is no restriction, my son never gives meat first, he eats whenever he wants, no, just eat a little, he is enough, why restrict?

As for the heat, we should not worry too much about it, everything has to be experienced by ourselves.

We can calculate how many calories are in food, and we can roughly calculate how many calories are consumed based on weight and exercise.

But all this is just a calculation thing, only theoretically meaningful, and in practice it has little significance, and it cannot be measured and calculated at all.

For example, we eat 1000 calories of rice, but the 1000 calories of rice into our stomach, our gastric juice according to the different composition, concentration of its effectiveness in decomposing food is not the same (here is not listed men, women and children, spring, summer, autumn and winter, morning, noon and night, hunger, fat and thin, etc., the impact of the human body on the secretion of digestive juice), but it is certainly not 100% decomposition, so it is basically impossible to accurately measure this 1 data.

For example, the digestive juices in our stomach are broken down by 60% of the 1000 calories of food (hypothetically), so how much is our intestinal absorption capacity of the 600 calories of the broken down food? And according to the different absorption capacity, this 600 calories is certainly not 100% absorption, and it is also impossible to accurately measure this 1 data.

Also, some foods are basically difficult for us to digest, but they also contain calories, such as peanuts, leeks, watermelon seeds, etc., etc., when we defecate, we can often see their limbs and grandchildren intact, so it is better to eat them yourself.

Body. When calories are consumed, body weight is on a downward trend;

When calories = calories burned, the weight remains basically the same.

Whereas. Calorie intake = Calorie intake from diet.

Calorie consumption = basal metabolic rate + total calories burned by physical activity + food caloric effect[1] = basal metabolic rate + total calories burned by physical activity + dietary calorie intake[2]*10%.

Therefore, when it comes to maintaining weight (at this point calories = calories burned), the optimal calorie budget, ie.

Dietary calorie intake = (basal metabolic rate + total calories burned by physical activity).

Analysis of the condition: Hello friends of Pengji, children around 12 years old need about 30 grams of protein, 23 grams of fat, and 120 grams of carbohydrates for a lunch. Lunch should be a little more nutritious, with a balance of meat and vegetables.

Suggestions: Hello friends, as far as the current standard of living is concerned, it is unlikely that there will be nutritional deficiencies, just pay attention to the combination of diet, and maintain a balanced balance of nutrition with food and drink.

Here are a few ideal foods to promote growth and maintain health and body shape:

1. 100% protein: protein can make excess fat in the body burn off quickly, make weight loss, and enhance the body's resistance to disease and fatigue. The intake of protein tona has great health benefits, which is the common opinion of experts.

2. Animal protein contains a lot of meat in meat, fish, eggs, etc.

3. Eggs: Among all kinds of animal proteins, eggs are the most important food. Eggs also have various amino acids that make cells, so eating eggs at the time of meal is sure to have excellent results.

4. Breakfast can not be omitted: there are many girls who are afraid of obesity, they ignore breakfast, in fact, in the eyes of Westerners, breakfast is the main meal of the day, no matter how much you weigh, breakfast must be eaten.

5. Eat less snacks: Snacks such as candy, chocolate, peanuts, etc., most of them contain high amounts of calories, which are really dangerous. Celery or foods with fewer calories.

6. The amount should be more blind and less calories: everyone has an appetite, different sizes, both want to satisfy the appetite and **, you should choose this kind of food, fruit watermelon is, even if you eat a full stomach, but there are almost no calories; Vegetable soup too.

7. Vitamin supplementation: As mentioned earlier, vitamins are the source of life, for beauty and nutrition, we must replenish sufficient vitamins every day.

8. Drink less alcohol: Because the calorie of Bacchus dregs is very high, it replaces the burning effect of fat, and the weight is naturally gained.

9. Exercise more: let the excess energy be consumed as much as possible, and it will be converted into fat when it accumulates in the body.

10. Eat more lettuce: such as carrots. Foods with few calories, such as celery, and lettuce are not cooked and the nutrients are not destroyed. Many models have a habit of reaching out to eat lettuce at any time.

If the child's snacks do not leave the mouth, the stomach and intestines are constantly holding and peristalsis, and the skin and the digestive juices secreted cannot be rested, which will cause digestive disorders in the long run. When eating, digestive juices are in short supply, and the food eaten stops in the stomach and cannot be digested and absorbed well, and the child has no appetite. Because the child has no appetite, he must not eat well, pick and choose, choose what he likes to eat, and gradually form a problem of partial eating.

Therefore, do not make your child develop the habit of eating repentant snacks.
