According to American scientists, reducing the amount of adipose tissue before pregnancy helps prevent obesity in children born to mothers with excess weight, according to an online edition for girls and women from 14 to 35 years old Pannochka. Net The obesity epidemic is spreading in many countries, and more women are overweight already before pregnancy. It is known that the children of these women are more likely to suffer from obesity in later life.

An animal experiment conducted by the Center for Pregnancy and Newborns Studies at the University of Texas, USA, showed that weight loss before pregnancy is beneficial to the weight of the unborn child.

Scientists observed two groups of female rats grown on fatty foods: animals from the first group continued to eat fatty foods during mating and pregnancy, while animals from the second group were transferred to less fatty foods one month prior to mating.

The offspring of females from the first group were born with poor parameters of fat metabolism (high levels of triglycerides, leptin, insulin, high resistance to insulin during weaning). Cubs of females from the second group had normal values ??of fat metabolism.

In addition, animals born from females consuming fatty foods were characterized by a large volume of adipose tissue and a large size of fat cells. These indicators were almost normal in young females who switched to low-fat food before pregnancy.

Peter Nathanielsz, the principal author of the study, says that he was especially interested in the increased level of leptin in cubs born from females with obesity. Leptin, this hormone, giving the brain a signal of saturation. It is likely that these cubs from birth are resistant to signals, which normally help stop eating and not gaining excess weight.

Scientists believe that their work will help in the development of dietary recommendations for pregnant women.
