Obesity Associated With Worsening Cognitive Function In Older Men

SOURCE: Medical News Today

DATE:  March 9, 2009

EXCERPT: "Older men with higher levels of fat appear more likely to experience declines in cognitive function over seven years, but the same association does not appear to occur in older women.

....

"Women show trends toward inverse associations, with higher levels of adiposity being associated with less cognitive change," the authors write. "Traditional metabolic factors, adipocytokines [compounds produced by fat tissue] and sex hormones do not explain this sex difference. Future studies should confirm these longitudinal associations with adiposity and cognitive change and investigate why adiposity has inverse associations in men and women.""   more

Fat Storage Depends On Gender

SOURCE: Medical News Today

DATE:  March 3, 2009

EXCERPT:  "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."    more
