Knowing More About Diet

In nutrition field, the diet is the amount of food consumed by a person or a specific organism. Type of diet is influenced by individual background or origin of the confidence a particular community. Although the human is essentially omnivora, a group of people usually have a preference or prohibition of certain types of food.
In development of diet, diet in the context of efforts to manage the nutrition Feed was divided into several types, namely:

• Reduce Weight (Mass), for example for the model or actress who wants to maintain the appearance.
• Increase the Weight (Mass), for example for the sportsman or athlete who want to increase muscle mass.
• Avoidance of certain food such as for diabetics (low-carbohydrate and sugar).
Feed nutrition affect someone very mass body.
Factors Affecting the Body Mass
Internal factors are responsible for their body mass is a factor that can not be controlled consciously by people who do diet.

Genetic factors
INSIG2
Research conducted by Boston University Medical School found that the genes called INSIG2 responsible for Obesity. Gen INSIG2 responsible to inhibition in fatty acid synthesis and cholesterol. Some of the protein products of genes Variant INSIG2 inhibition have a low power so that people with the variant genes will tend to accumulate more fat in the body. Approximately 1 out of ten people (10%) suspected of carrying this variant genes.

FTO
Other genes responsible for the FTO Obesity are gen. FTO is the name of the genes located on human chromosome 16. Based on the research of those who have certain variants of FTO and a pair alel homozigot variants in genome (16.4% of the subjects of research) has a weight of 3 kg body weight of more people fell ill and have a risk 1.5 times Obesity more than the ordinary person.
Thermal regulation

Man are essentially warm-blooded creatures spending energy to maintain body temperature. In addition to need energy to maintain body temperature (average 37 OC), a number of energy is also required to maintain activity vital organs like heart and lungs. The necessary energy comes from food that is consumed by someone.

Generally, in sleep, people need power of 1 Watt per kg of body weight (men with 65 kg body weight will consume power about 65 Watt or roughly equivalent to the power needed for the two light bulbs). With body weight 65 kg, the consumption of energy needed by the people that every day is kilojoules around 5500 or 1400 kilocalorie (kkal). Energy needed for a human life (in the rest condition), without doing any activity before with a Basal metabolic Rate (Basic Rate Metabolite / BMR).

Thermal regulation mechanism of each person is different and the energy consumption determines how much nutrition that must be burned by the body to produce energy is. Thus, the higher the BMR someone, the higher the consumption of energy and people need more food to maintain body activity. Differences in gender, race, and also affect the value of high BMR. Psychological conditions and temperature also influence.

Because the total calorie needs for each individual is different and depends on gender, age, and ethnicity. Nutrition experts generally use the Harris Benedict formula to produce a more accurate estimate of the value of BMR someone. Instead of counting their own, while there are many internet sites that have provided a simple program to calculate the BMR for example program called BMR Calculator.

Metabolism
Metabolism, in short, is the process of processing (formation and decomposition) oxygen-oxygen that is required by the body to function. Metabolism of fat is a key factor in the diet. One can increase the burning of fat by increasing muscle mass in the body. When muscle mass increases, food increases metabolism. This process will increase the value of BMR and calorie needs.

External factors
Based on research conducted on the population of the United States, there are 60.5% of the population aged adults experiences the condition of excess body weight (2005 data). Based on this data, some experts believe that the living habits and eating patterns hold a more dominant factor in affecting body weight if someone compare with internal factors. Two external factors that are very dominant physical activity and nutrition feed. One can easily reduced without the need consume drugs and such fat burner by increasing the activity and reduce food to Feed in the body.

Physical activity
To perform physical activity, people need some energy. If the energy provided by food is not enough, the energy obtained from the splitting of fat in the body. Here is an example of physical activity and the calories burned per hour (in kkal / hr) required for each activity.
Feed Nutrition
Body weight can be derived easily with the way restrict Feed nutrition. Multiplier factor for the energy received by the common people are as follows: 1 gram carbohydrate yield 4 kkal, 1 gram protein 4 kkal, and 1 gram fat 9 kkal. The figure with the value of BMR calorie needs per activities, one can easily
