They taste delicious, outrageously good, but once you have passed our taste buds, fat, sugary foods that many of us do not love anything for the rest of our body. However, they are still (for many of us) almost impossible to resist. If our diet to be unhealthy a gene related to fat?

New research out of Scotland appears to support this theory – find a gene variant linked to obesity and can also lead us to be attracted to fat, sugary foods, so you eat about 100 calories per meal.

The gene, a variant of the FTO gene is believed to be part of the composition 63% of the population. And while this gene does not mean they are destined to obesity, or lack the means is clear thinking – in the short term is not binding the two together.

The new study has worked to confirm this connection, and then took things a step further to see how the FTO gene variant may influence obesity.

The research employed a large group of 2,700 schoolchildren in Scotland as subjects, measuring their weight, height and hip circumference and that the taking of saliva samples to find the children with the FTO gene variant. As expected, the heavier children were more likely than genetic variation.

What really care experts is the next stage of the study.

Here, the monitoring team of the metabolism of a small minority but important children enrolled in 10 days.

These subjects also ate the special test in school. These meals have been carefully weighed before and after the children ate, if the amount consumed can be measured accurately.

Surprisingly, the FTO variant has a slower metabolism, but it was linked to eating more calories during the meal itself.

The researchers found that those who choose other foods with more fats and sugars … suggesting a random instinctive these options instead of healthier options.

The study found that the variant had no impact on the speed of food body or level of activity of a person is. Nor was there evidence that those with the gene had difficulty recording when full and stop eating at that time.

The subjects with the variant of FTO were simply produced more high-calorie foods.

Lead researcher Professor Colin Palmer said: "This work shows that this gene does not lead to obesity, not overeating, and suggests that obesity linked to this gene may be modulated by regulating supply carefully. "

Earlier work in this field has shown that people with a copy of the key FTO variant (about 50% of the population) have a 30% risk of obesity.

If you have two copies of the gene, the risk increases to nearly 70%.

Couple wanted for possible genetic fatter, the sugary foods, and the availability of these types of foods and can see why obesity rates are increasing steadily.

The work appears in the December 11, 2008 in The New England Journal of Medicine. An editorial by Dr. Rudolph Leibel, MD, Columbia University, published with the study, the importance of style factors life in two to allow or restrict susceptibility to overeating and overweight or obesity.

But the idea that all you need do is make a better choice food and other habits of life ignores the idea that we are not all equal in terms of how we look on fatty foods and sugar Laden. It could be more difficult for some people with the gene for the fat to resist unhealthy food choices than others.
