Guide calories and nutritional values

Energy in food is the amount of heat produced when you burn food in the body. Food and vary in the amount of energy generated on the content of the essential elements in food, and there are some carbohydrates, proteins and fats.
Measured energy from the burning of food Basarp heat (calorimetry).

What is a calorie?

Calorie Calorie (Kcal) is the amount of heat (energy) needed to raise the temperature of 1 kilogram of water 1 degree Celsius. It is worth mentioning here that the Calorie (calorimetry) Calorie is already Kcal Kcal, but for short became a calorie and write in English with a letter the CIA Big Capital letter. It is important we know what is the definition of Calorie and is a unit for measuring the energy that the body needs to live and move and perform all the basic functions of life. Food is the source of energy and the human body needs all the food sources of carbohydrates (starches) Carbohydrates and proteins Proteins and fats, fat.

The body needs these natural sources of energy production in different proportions
- Carbohydrate 50%
- 35% fat
- Proteins 15%
Can not delete the fat from the food it contains the so-called essential fatty acids Essential Fatty Acids, which the body can not be devised then your must be obtained from food and are very essential for the body Fbnqsa produce some diseases, as well as vitamins soluble in fat (vitamin A, E, D and K).
Human needs a certain amount of calories a day, and increased activity by the person and his body size (height and weight) as well as age. Children and young people in the growing need for greater amounts of calories. There must be a balance between the calories we take from food and calories you burn in order not to increase our weight where the body stores the extra calories it needs in the form of fat for use later, if forced to it (in case of lack of calories derived by eating ). If you overvalue eating increases the amount of fat and reduced eating if the body uses fat to produce energy and burn less fat then your have.

What is the metabolism or metabolism Metabolism?

Metabolism is the term for each of the physical and chemical processes that occur in the body to produce the contents of living cells and maintain them, as well as operations are being conducted to produce the energy needed by the body. Is simply the process of burning calories in the cells of the body to sustain life and to the movement and activity.

What do I do in order to keep the weight?

Down streams of energy and calories and then calculated the amount of energy (roughly) that its disposal is calculated daily and the amount of calories you eat and do not exceed the maximum allowable daily calorie .


(male): Calculated and approximate your ideal weight for height :
48 kbps to 150 grams centimeter length + 1 kg per 1 centimeter length above 150 centimeters.
(Female): 45 km to 150 grams centimeter length of 0.85 kg per 1 centimeter length above 150 centimeters.
Example height 160 centimeters, the ideal weight = 48 +10 = 58 kg
Need from 0.45 - 0.8 grams protein per kilogram of ideal weight per day.
Of the exercises you need from 1 - 1.2 grams per kilogram of ideal weight per day. (more thing 2 grams per kilogram of ideal weight per day).
More than 2 grams per kilogram of ideal weight per day is not good for you and cause you health problems such as lack of calcium and vitamin B-6 and osteoporosis not to mention the pressure on the kidneys.

What are the factors that determine the amount of energy expended per day?

Energy Expenditure energy expenditure or the amount of energy that the body puts it (calories burned) depends on:
  • BMR Basal Metabolic Rate, and is the energy that the body needs daily in order to preserve itself and live (for survival). Parcels and increase with increasing body mass Alhebrp (body weight from muscle and bone and water) Lean Body Mass, as well as an area of ​​the body. They are higher in men than women, and high in children and in cases of fever, hyperthyroidism, and are low in hypothyroidism and starvation.
  • Thermal effect of food Thermogenic Effect of Food is a 50-10% of total energy expenditure by the process of digestion in the digestive tract and stimulate (increase) the metabolism Metabolism in the body when entering the food (new energy) in the body.
  • Activity and Movement and Physical Activity is a variable factor with the greatest impact on energy expenditure, which could increase the rate from the case of comfort and relaxation to 10 times in the exercise of extreme sports.
  • The temperature of the environment Environmental Temperature when the heat is paid for the body extra energy and warmth when the temperature of the body the body spends additional energy for cooling.

Many people ask, what is the brown fat Brown Adipose Tissue?

Works in brown fat heat production Heat Generation, particularly in animals, for example, after wake up from hibernation or living in cold regions and in the offspring to produce heat. Fat brown is not a tissue prominent in the human body, but in some people, be active so that explains how some people eat and do not Ismonon it burn excess calories or activates when a person eats, generate heat Ballokl Diet Induced Thermogenesis, and it is noted that the amount of fat Asmar be low or non-existent in people fat.
