It's a paradox that has flummoxed women for generations — their apparent ability to store fat more efficiently than men, despite eating proportionally fewer calories. While it has long been suspected that female sex hormones are responsible, a University of New South Wales UNSW research review has for the first time drawn a link between one hormone — oestrogen — and its impact on fat storage for childbearing.
On average, women have 6 to 11 percent more body fat than men.
Studies show oestrogen reduces a woman's ability to burn energy after eating, resulting in more fat being stored around the body. The likely reason is to prime women for childbearing, the review suggests. The findings, which appear in Obesity Reviewsmay have implications for dietary advice given to women during pregnancy and the de of exercise regimes.
The question is why does this paradox exist?
An obvious answer is that fat storage by women gives an evolutionary benefit, he said. However, additional research was needed to provide more insights into the role of oestrogen in the regulation of body fat. Associate Professor O'Sullivan stressed that while oestrogen's effects on postprandial fatty acid oxidation provide a mechanism for fat accumulation, the findings do not explain why some women are obese.
Factors contributing to obesity are complex and include both genetic and environmental factors, he said. Materials provided by University of New South Wales.
