How many calories should I eat a day to lose weight?

Babies who want to lose weight should not feel unfamiliar with the word calorie, right? Are you thinking about food calories every time you eat, wishing you could count them clearly? Try to choose low-calorie ingredients when eating, and be shy about high-calorie foods. But the editor wants to say, do you really know the caloric value?

What is heat?

Heat is something used to keep an organism active and consume kinetic energy. Lung inhalation, heart trembling, gastrointestinal motility, walking, waving, every movement you make consumes heat. We are small animals without chloroplasts and cannot produce energy through photosynthesis. We can only use our lips to absorb food and obtain energy.

Food releases energy through redox reactions in the body, which is the heat we need. The raw materials are carbohydrates, fat and protein in food.

How to measure calorific value?

The measurement of calorific value is based on how many degrees the kinetic energy caused by the food being completely ignited in the water heater can cause the water to rise. For every 1 ml of water to increase the temperature by 1°C, 4.184 joules are required. This is the measurement of kinetic energy.

But in fact, the caloric value on the package is not measured accurately. Second, it is calculated using the formula, caloric value = (carbohydrate weight g protein weight g) * 4 fat g * 9 calories.

Will the calories of the same food change?

The caloric value of the same food is different in different situations. For example, boiled chicken breast. If you pick up 200g of freshly bought chicken breast, only 150g may remain after boiling. However, the caloric value of fresh 200g and cooked 150g is the same. Their caloric density is different. Therefore, you should pay attention to the condition of the food when using a computer or heat meter to look at the data.

In addition, boiled chicken breasts and fried chicken breasts, because the latter absorbs a lot of fat, will also cause food calories to soar.

So how many calories should you consume every day?

Generally, the caloric value of the general group is maintained at 1600-2000 calories, which can maintain the body shape. The caloric value of the fitness and muscle-building group is maintained at 2000-2500 calories. As the muscles increase, the caloric value will continue to increase, so we need to tailor it according to our own conditions.

Therefore, people who want to lose weight need to reduce their caloric intake and do more exercise to consume calories. We need to control heat rather than use heat to control your daily life.
