Fat tissue controls brain's response to food scarcity, helping regulate optimal amount of body fat for brain function An enzyme secreted by the body's fat tissue controls energy levels in the brain, according to new research. The findings, in mice, underscore a role for the body's fat tissue in controlling the brain's response to food scarcity, and suggest there is an optimal amount of body fat for maximizing health and longevity. The findings may help explain the many studies that show a survival benefit to having a body mass index toward the low end of what is considered overweight.
Sugar and carbs, not physical inactivity, behind surge in obesity  Excess sugar and carbs, not physical inactivity, are behind the surge in obesity, say experts. It is time to bust myth that anyone -- including athletes -- can outrun a bad diet,
