A slender figure prevents women from getting pregnant - study

Skinny women are less likely to become pregnant than women who are overweight

That is the conclusion drawn by researchers of the Center of Fertility in Chicago analyzed data from nearly 2,500 procedures in vitro fertilization (IVF), which were held in the facility for eight years, according to meddaily.ru with reference to the Times of India.

Women who participated in the trial were divided into three groups according to their weight - a very thin, normal or obese. After IVF in the group with normal weight pregnant almost 50% of women among the total - 45%, while thin in the group - only 34%.



Scientists note that the category of very thin women is having a body mass index (BMI) of 14 to 18. In this case, the woman with the growth of 162.5 centimeters and a weight of 44.5 kg would have a BMI 17, and the woman with the growth of 177.8 centimeters and weighing 57 kilograms - BMI 18.

Previous studies have found that very thin women are more difficult to conceive naturally due to the decrease in their body level of the hormone estrogen. However, in this study, women undergoing IVF, received additional hormones.

In addition, all women of the same number of eggs tucked, of which the researchers concluded that the problems in very thin women appeared at a later stage.

Scientists also believe that the decreased ability of thin women to conceive may be associated with evolution.

Greasy Foods

Scientists have explained the phenomenon of greasy food appetite

Scientists from the University of California at Irvine (USA) found that the fat in potato chips and French fries start in the human biological mechanism that controls our appetite

Appetite of a person depends on the natural chemicals marihuanopodobnyh - endocannabinoid. Through experiment, researchers found that when rats have tried something bold, the cells in the upper part of the digestive tract started to produce endocannabinoids. Sugars and proteins do not have this effect, the researchers note, writes Kompyulenta.

The process begins in the language in which fats from foods generate a signal which first goes to the brain, and then through the vague nerve in the intestine. There's the signal stimulates the production of the endocannabinoid, which cause increased signaling cells, and this gives rise to formidable desire to consume fatty foods without measure. This is probably due to the fact that the body begins to produce chemicals related to hunger and satiety.

The current study led by Daniel Pamela, first revealed that The EC signaling in the gut plays an important role in the regulation of fat intake. In modern society, fat is widely available, so the natural craving for fat and leads to obesity, diabetes, cancer.

According to scientists, if suppress the activity of the endocannabinoid, for example, with medication, "pollute" cannabinoid receptors, we can solve the problem of obesity of the population.
