Eating Less May Not skinny, Can Also Excess Chromosome
Jakarta, Got a skinny body often gives the impression of lack of nutrition, when in fact been fed with the correct pattern. According to research, some people are just born to thin forever because it has the advantages of a gene called gene-16.
Normally, a person inherits the composition of the same gene from both parents. But in some people certain genes could have duplicated that number to 2 times as much, or removal so that the composition is reduced.
A study done by scientists from Imperial College London in England and the University of Lausanne in Switzerland revealed that the composition of genes numbered 16 or so-called gene-16 can affect weight. Someone who had the gene duplication will stay thin despite eating a lot.
In contrast to people who lose some of these genes, their weight is believed to be easier to increase even though his diet the same as another. As a result, though it was trying to diet, her body still tends to look fat.
Research involving 95,000 people revealed, duplication or multiplication of gene-16 experienced by 1 in 2,000 people worldwide. In males, this condition increases the risk of underweight by 23-fold and 5-fold in women.
Underweight or very underweight defined by body mass index (BMI) below 18.5 kg/m2. The opposite of underweight is overweight if the BMI is in the range 25-29 kg/m2 or obese if the BMI has exceeded 30 kg/m2.
Besides increasing the risk of underweight, which makes the composition of gene duplication-16 is too much too risky trigger microcephalus or shape of the head is too small. Because of the small head, brain volume is limited so susceptible to damage nerves and the average life expectancy is shorter.
"About 25 percent of thin people who have a gene duplication-16 also had microcephalus," said Philippe Froguel of Imperial College London, as quoted by Reuters on Thursday (03/11/2011).
