Prevalence of Overweight

As Obesity is a by too much fat tissue, increased body weight. The subject, more and more Europeans. According to a WHO report from the year 2010, over 50 percent of the people in Europe are overweight or obese, and approximately 20 percent are obese. Nevertheless, Obesity is seen primarily as a cosmetic Problem rather than a disease with significant health risks and costs.

Energy budget

What happens in our digestive tract after eating, can simplified be described as follows: The main enzymes are the nutrients through digestion into their smallest component parts, carbs into Sugar units, proteins into amino acids and fats into fatty acids. This reach of the stomach and intestines into the blood and ultimately into our cells, where they serve as a construction and replacement materials or as an energy supplier.

Energy production and storage

The provision of the of our body the required energy by combustion (oxidation) of nutrients and is subject to strict rank order. Alcohol is first burned, because the body of alcohol calories has no storage mechanism. Carbohydrates are burned at the second position. You are, as glucose is the main fuel for our body, especially our brain. We eat carbohydrate-rich food increases the glucose level (blood sugar level), depending on the length of the carbohydrate chain (fast-usable single or double sugars, and complex carbohydrates) more or less quickly.

The pancreas, which controls blood sugar, the hormone Insulin into the blood sugar level to normalize. The excess glucose is transported into the reservoir storage of muscle and liver (total memory capacity approximately 500 grams) and starch (glycogen) is stored. From here, you can, if necessary, that is to be retrieved in the case of a low glucose level very easily.

With too high a carbohydrate, our body converts the Excess into fat. So, we can be too thick to eat without fat. The protein utilization is relatively constant. To cover the daily requirement of 1 gram of Protein per pound of body weight. Is eaten as part of a diet less than 50 to 60 grams, the body draws on its own protein. This can cause a reduction in the muscle mass.

Fat in body fat convert

Fat burning is the final stage in the energy Oxyidations delivery hierarchy. It is not only necessary when the supply of carbohydrates (glucose) alone is sufficient. The energy requirement of the body through carbohydrate oxidation is covered, will be converted into the absorbed fat into body fat and stored. The storage capacity for fat is very high. It is even at a normal weight, the 150-times the daily intake. If the consumed carbohydrates are not sufficient to cover the energy needs, dietary fat oxidized. The fat deposits will only be attacked if the energy consumption is higher than the offer from the food. The grease supplied is determined, so that only the stored fat calories and not the burned.

Any excess energy goes as a Deposit in our fat cells. A daily Excess of only 22 kcal (equivalent to, e.g., 1/13 Hamburger) leads within one year to a Surplus of about 8,000 kcal and a weight gain of one kilogram.

Weight loss

In order to keep your body weight, you need to adjust your energy intake to your needs. You want to lose weight, you need to put into your body less energy than it consumes.

So the organism is forced to draw on its reserves. In his “famine,” he uses first the easily accessible glucose reserves. He brings the missing calories from the glycogen store of the muscle and liver. Since each glycogen unit is bound to several molecules of water, the body loses when you Burn a lot of water.

Then he starts with the removal of valuable body protein. At the beginning of a diet you will lose weight, but no fat. So it is not a real weight loss. The removal of fat from the adipose tissue starts only after about one week on a diet. The weight now decreases slower than in the first few days.
