Why millions of people fail to lose weight

Hungry all the time and you fail to stick to a diet? Researchers have discovered the real reason some people cannot refrain from sweets and fatty foods.

It is a DNA sequence problematic - some variant of the FTO gene - which prevent people feel tired and often makes them feel cravings for sweets and fatty foods, scientists say.Visit my Web Pages http://www.fatlosspot.com/venus-factor-review/

In a few years, was discovered FTO gene, which is known to have a role in obesity, but the mechanism behind this association was still unknown. Now, scientists have deciphered the mystery of the influence of the FTO gene on body weight.
Knowing how the gene works may explore new ways to counteract its influence to combat obesity which in many countries and Western, tends to gain a true epidemic proportions.

Millions of Britons, for example, carries a problematic version of this gene (about half of the population, according to researchers consider), either in a single or two copies (as when we speak of "gene" it is in reality , of a pair of genes located on chromosome pairs, in this case, two copies of the FTO gene in the chromosome of a pair are 16).

The 16% of the population bearing two copies of the defective gene variants have 70% higher chances to become obese than those who do not have a copy of the FTO gene variant. Even the 49% who have one copy of the gene problematic 30% higher chance of becoming obese.

People who have this variant (named by scientists "obesity gene" or "gene hunger") tend to eat more and more often, fails in an attempt to lose weight through diet.

The mechanism of this gene involves a hormone called ghrelin, responsible for the sensation of hunger. People who have "obesity gene" does not show a significant decrease in ghrelin levels after they ate a normal amount of food, which causes them to eat a lot.

Researchers at University College London asked some young men (some of whom gene problems and others do not) to assess the intensity of the sensation of hunger before and after a meal. Volunteers were taken blood samples by measuring the plasma levels of ghrelin, the hormone which triggers the sensation of hunger.
