In
our time, calories are very fashionable - and we do employ the burn, feel, and shave, and it would be incredibly difficult to go to the grocery store to find the product on the packaging of which has not been shown to its calorie content. But can you tell what the calories are and why they are special? In this article we describe the essence of calories, about why we need them, and trace the relationship between calories and body weight.
What is a calorie?
Calorie - a unit of energy equal to the amount of heat required to heat one milliliter of water by 1 degree Celsius, and is equivalent to 4.184 joules. We are accustomed to associate calories with food, but in reality they are relevant to anything that is capable of producing energy. For example, a liter of gasoline contains 7.75 million calories.
When we read the label on a carton of yogurt, we see a certain number - the number of calories that the body will receive the full assimilation of the contents of the box. In fact, there are usually referring to kilocalories (1 kilocalorie = 1000 calories), but not always and everywhere it is written.
The same applies to the exercise, when on a table in the gym says that every traversed kilometer on a treadmill you'll burn 100 calories, meaning 100 calories. In this article, speaking of calories, we will also mean kilocalories.

Calories, fat, and exercise
So, what happens if you get more or fewer calories than your body burns? You gain or lose fat, respectively. For example, the accumulation of additional 3500 calories your body will stock the approximately half a kilogram of fat - so the body creates reserves in case a hungry time. On the other hand, if you have some time to burn 3500 calories in addition to those that you already spend every day, the body will translate into energy of about a pound of your fat reserves.
As for exercise, you should know about them is one important nuance. Exercise increases the metabolic rate not only while puffing on the treadmill, but within two hours after the workout, because metabolism takes a while to get back into normal rhythm of work.
Many people have asked whether a value source of calories. In general, if we get the food as many calories, how much spending, and if we are only talking about weight, it does not: a calorie is a calorie. In this aspect, the calories derived from fat, no different from the calories, proteins extracted from all of them - simply units of energy. As long as you burn as much as you have, your weight will not change, and if you burn more than purchased with food, you will begin to lose weight.
But if we remember about the nutritional value of nutrients, we find it extremely important to the origin of calories. Carbohydrates and proteins are much more valuable source of calories than fat. And, although the human body needs to function properly in a certain amount of fat (with fat body gets vitamins from food), the excess fat in the diet can cause serious health problems. Managing for Quality Control of Food and Drug Administration (USA) (US Food and Drug Administration) recommends monitoring in order to get from fat to 30% of daily calories. This means that when a 2,000 calorie diet on the proportion of fat should account for no more than 600 calories - 67 grams. However, many doctors and nutritionists say that the maximum - it is 25%, for a total of 56 grams per day for 2,000 calories per day.
