Weight gain ” Ideal ” during pregnancy depends on the initial weight women : it is thus 5 9 kg for a body mass index greater than 30, 7 11 kg for a BMI between 25 and 29, 11 to 16 kg if BMI is between 18.5 and 25 and finally 13 18 kg if BMI is less than 18.5 kg.

Through an extensive survey conducted in Northern California, the researchers analyzed data from 4,145 women who gave birth between 2007 and 2009, and followed the medical records of children between the ages of 2 and 5 years.

Their findings, published in the American Journal of Obstetrics and Gynecology, shows that 20.4 % of children whose mothers had taken more than the recommended weight during pregnancy are obese or overweight.

Nearly 19.5 % of those born to mothers who took little or not enough weight suffered from similar disorders.

This figure rose to 14.5% for women whose weight gain was “Normal” or similar to the recommendations made.

Researchers have noted that women whose BMI was normal before pregnancy but who took more than the recommended weight had an increased risk of 80% to the world a child who would later become obese or overweight.

” This association is independent of genetic factors,” recounts Dr. Monique M.

Hedderson, co- author of the study.

” Taking too much or too little weight can affect long term ” the mechanisms that control the regulation of energy balance and metabolism, such as appetite and energy expenditure, Sneha says Sridhar, lead author of this study.

Do everything possible to stay slim during pregnancy is not necessarily a good idea, no better than eating for two!

Maternal gestational weight gain and offspring risk for childhood overweight or obesity.

in these animals in all cases.

Laziness is associated with genetic predisposition, recognize Franck W.

Booth and Michael D.

Roberts and the team from the University of Missouri ‘s College of Veterinary Medicine, which published the findings of their study in the latest issue of the American Journal of Physiology.

The researchers selected fifty rats they locked in cages with a rotating wheel and calculating six days the period during which these rodents voluntarily climbed on the wheel.

They then mate the 26 best-performing rats and repeated operation for 26 more lazy, and, for ten generations.

The researchers then found that the rodent lineage after rats ” Champions ” could run ten times faster than the lazier group.

They then proceeded to genetic evaluation based on the DNA profile of rodents to establish that, on the 17,000 genes present in a part of the brain, at least 36 were identified that may play a role in motivating do or not to exercise.
