What is a calorie

Calories are units of energy, which is formed by the assimilation of a product. The standard calorie is the amount of energy equal to the amount of heat required to heat one gram of water by 1 ° C. The main source of energy is carbohydrates. If they are not enough, "the furnace" are fats and proteins, which provided uninterrupted flow of carbohydrates are used for other purposes.

It has been established that 1 g of fat contains 9 calories, and 1 g of carbohydrate and protein - 4 calories. But the products we use, often have a mixed composition, so each product has its own caloric content, that is, how many calories are in 100 grams of a product. For convenience, this ratio calculate in kilocalories (kcal 1 is equal to 1000 calories). Naturally, fatty foods are the most calorie. With table calorie products, anyone can calculate how many calories he eats a day, compared with the existing rules.

How many calories per day is required to man

Different people need different amounts of calories. For example, men need more calories per day than women because they have more intense metabolic processes occur that requires extra energy. More calories needed and the young, especially the body is still growing, but in the elderly received a large number of calories can be harmful: the body simply can not cope with the processing of large quantities of food. The number of calories per day depends on what people want to achieve: to lose weight, build muscle, recover or just to lead an active healthy lifestyle.

For example, young women who are not engaged in heavy physical labor rate is about 2800 kkakl a day, for men of the same age - 3300 kcal per day. If a person is engaged in heavy physical labor or sports, the number of calories increases: for women - up to 3,500 for men - up to 4500. The increased number of calories per day is required for pregnant (until 3200) and lactating women (3500). In old age, and sedentary women enough 2100 calories, and men - 2500.

How to calculate calories to lose weight

In order to lose weight, you need to get from food fewer calories than they expended by the body. But there is one caveat - the body must receive a minimum basic rate of calories, which should ensure the flow of biochemical processes (including metabolism develops), the function of internal organs and physical activity. If the diet is so limited that it can not cover the basic costs of energy, then the person will not lose weight: the body is just going to waste less energy, resulting in lower metabolism, lethargy and disruption of the whole organism. And the weight will not decrease, on the contrary, the body under conditions of extreme energy shortages manages to something else and put off a reserve in the form of fat.

To properly calculate the amount of calories required per day to lose weight, you can use a simple method, which is used in England and the United States (in these countries adhere to the lower daily rate). For this purpose calculated daily allowance of calories to maintain current weight, and that weight you want to achieve. Weight is calculated in pounds (one pound is equal to 0, 453 kg) and multiplied by a factor of 14.

Example of calculation. A woman weighing 65 kg wants to reduce his weight to 55 kg. To maintain current weight it should be consumed in a day: 143 7 lbs (65 kg 0 kg 453) x 14 = 2012 kcal per day. To reduce the weight to the desired 55 kg: 120 (55: 0, 453) x 14 = 1680 kcal. In order to reduce its weight to 55 kg, this woman should consume no more than 1680 kcal per day.

How to calculate the calories to build muscle

Now in vogue beautiful male body and a lot of men pumped up muscles in the gym to give them relief. But some physical exercise to build muscle is not possible, it requires special food. Firstly, the energy value (caloric) it should exceed the daily energy consumption (calculation is the same as for weight loss, only the desired weight should be more than the original), and secondly important is the quality of the food you eat, because build muscle mass which consists of proteins, hence, food must contain an increased amount of protein.

Independently calculate the load and the power required for this is rather difficult, but there will always be able to help coach who will calculate an individual diet and stress. It is only necessary to know that to achieve the beauty of the body should not take anabolic hormones that promote good absorption of protein, but give a lot of complications.
