Mouse study: When it comes to living longer, it's better to go hungry than go running

May 14, 2008 - American Journal of Physiology: Reg, Integrative & Comp Physiology

A study investigating aging in mice has found that hormonal changes that occur when mice eat significantly less may help explain an already established phenomenon: a low calorie diet can extend the lifespan of rodents, a benefit that even regular exercise does not achieve.

Genetic variation linked to sugary food

May 14, 2008 - EurekAlert / Physiological Genomics

A new study finds that individuals with a specific genetic variation consistently consume more sugary foods. The study offers the first evidence of the role that a variation in the GLUT2 gene - a gene that controls sugar entry into the cells - has on sugar intake, and may help explain individual preferences for foods high in sugar.

Yerkes researchers find link between psychological stress and overeating

May 13, 2008 - EurekAlert / Physiology and Behavior

Researchers found socially subordinate female rhesus macaques over consume calorie-rich foods, resulting in accelerated weight gain and an increase in fat-derived hormones. The study is a critical step in understanding the psychological basis for the sharp increase in obesity across all age groups since the mid-1970s.

Scientists have shown that a receptor called ALK7 plays important roles in the regulation of body fat deposition as well as the release of insulin from beta-cells in the pancreas.

Sweeping analysis of research reinforces strong media influence on women's body image

May 12, 2008 - EurekAlert / Psychological Science

New technique determines the number of fat cells remains constant in all body types

May 9, 2008 - DOE/Lawrence Livermore National Laboratory / Nature

The number of fat cells in a human's body, whether lean or obese, is established during the teenage years. Changes in fat mass in adulthood can be attributed mainly to changes in fat cell volume, not an increase in the actual number of fat cells.
