What is Diet?

Diet is the amount of food consumed by a person or a particular organism. This type of diet is influenced by the origin of individual background or faith of a particular community. Although humans are omnivores essentially, a group of people usually have a preference or avoidance of some foods.
Unlike in a mention in some countries, in general, the word diet is more often intended to refer to an effort to lose weight or adjust the intake of certain nutrients. This article will discuss about the diet in terms of a second.

Diet in the context of efforts to regulate nutrient intake is divided into several types, namely: - Lose Weight (Mass) for the Agency as a model or actress who wants to maintain its appearance.
 - Increase Weight (Mass) Agency for sports such as bodybuilding or athletes who want to increase muscle mass.
 - Abstinence Against Certain foods such as for diabetics (low-carb and sugar).Nutrient of someone is very influential on her body.

Nutritional intake Weight loss can be derived easily by limiting the intake of nutrients. Multiplier factor for the energy generally accepted by many people is as follows: 1 gram of carbohydrate produces 4 kcal, 4 kcal 1 gram protein, and 1 gram of fat 9 kcal. By adding value peraktivitas BMR calorie needs, one can easily predict the results of his diet.

If calories in > calories out, then the rest of the calories will be stored in the body.

If calories in < calories out, then saving calories (fat) will be used to cover the energy deficit.

Calories entry is calories obtained from the food, while the calories out is the calorie requirement for BMR plus the calories per activity.

For example a person weighing 70 kg, has a large range of energy needed for basal metabolism of 1450 kcal. In one day, he performed jointly conduct the following activities:
- Walking (normal) with a speed of 3 km / h with a total time of 3.5 hours (480 kcal).
- He also swam (normal) with a speed of 23 m / min (alternating pools with normal speed) the total time of 1 hour (275 kcal).

That day, he ate the following foods (The number of calories listed on the menu is a general estimate. The condition is actually very dependent on the amount of food and its processing, for example, the sandwich will have lower calories when bread was replaced with wheat bread, or full cream milk is replaced with skim milk):

Breakfast, 7:00 (total 650 kcal)- Sandwich meats, mayonnaise, cheese (500 kcal)
- Full cream milk (150 kcal)

Lunch, 12:00 (total 550 kcal)- Rice (200 kcal)
- Soto Sapi (200 kcal)
- Orange juice with no sugar (50 kcal)

Dinner, 19:00 (Total 1530 kcal)- Pizza (680 kcal)
- French fries (800 kcal)
- Apples (50 kcal)

From the menu list above, obtained the total energy consumed by 2730 kcal. Basal rate of metabolism and the many activities undertaken, obtain the person's energy needs by 2565 kcal. Although he had been exercising (swimming) is not worth the energy expenditure of energy intake. As a result:

Calories in > calories out
The remaining energy (165 kcal, from 2730 kcal - 2565 kcal) will be stored in the body and one form of energy buildup is fat.
