Weight Loss Research: switch voracious eating 'on' and 'off' ♦ New strategies to control diabetes ♦ Late-night snacking: Is it your brain's fault?

Why do obese men get bariatric surgery far less than women? Demographic, socioeconomic and cultural factors contribute to a major gender disparity among US men and women undergoing weight loss surgeries. Men undergo the surgeries in far lower numbers than women, researchers report.
New tool can switch behavior -- such as voracious eating -- 'on' and 'off' Researchers have perfected a noninvasive "chemogenetic" technique that allows them to switch off a specific behavior in mice -- such as voracious eating -- and then switch it back on. The method works by targeting two different cell surface receptors.
Thoughts drive dieting plans but feelings drive dieting behavior, Dieting is a process that involves a plan to change eating behavior and behaving according to that plan. But the factors that guide diet planning differ from those that guide actual diet behavior.
Molecular link between high glucose, metabolic disease may offer new strategies to control diabetes Scientists say they've discovered a cause-and-effect link between chronic high blood sugar and disruption of mitochondria, the powerhouses that create the metabolic energy that runs living cells. The discovery sheds light on a long-hidden connection and could eventually lead to new ways of preventing and treating diabetes.

Late-night snacking: Is it your brain's fault? New light has been shed on why you, your friends, neighbors and most everyone you know tend to snack at night: some areas of the brain don't get the same 'food high' in the evening. The study also reports that participants were subjectively more preoccupied with food at night even though their hunger and "fullness" levels were similar to other times of the day.
