Losing weight is tough for women, study

According to a new study by a team of researchers, the gender of a person affects in their ability to lose weight as women find it difficult to lose weight than men.

Scientists led by the University of Aberdeen in UK found evidence that the gender affects the ability to lose weight. They said that it is harder for women to lose weight compared to men because their brains are wired differently. The study was carried out by researchers from University of Aberdeen in collaboration with those from the University of Cambridge and University of Michigan.

They used a mouse model to study sex difference in weight gain based on differences in physical activity and energy expenditure. They were able to transform obese male mice with increased appetite and reduced physical activity into lean, healthy mice but the same transformation did not happen for female mice in the experiment.Experts said that the findings of the study could have implications for the development of new sex-specific medications in order to better tackle the issue of obesity in men and women separately.

The team said that cells in the brain region make brain hormones called pro-opiomelanocortin (POMC) peptides that are responsible for regulating our appetite, physical activity, energy expenditure and body weight. However, the POMC peptides does not strongly modulate physical activity or energy expenditure in women compared to men.

Lora Heisler from University of Aberdeen who led the study, said, "The World Health Organisation (WHO) reports higher rates of obesity in women worldwide, reaching twice the prevalence of men in some parts of the world. We have discovered that the part of the brain that has a significant influence on how we use the calories that we eat is wired differently in males and females."
