Why can we get up for a piece of chocolate, but never because we fancy a carrot? Serge Luquet's team at the "Biologie Fonctionnelle et Adaptative" laboratory (CNRS/Université Paris Diderot) has demonstrated part of the answer: triglycerides, fatty substances from food, may act in our brains directly on the reward circuit, the same circuit that is involved in drug addiction. … [Read more...]

A University of Illinois study finds that obese children are slower than healthy-weight children to recognize when they have made an error and correct it. The research is the first to show that weight status not only affects how quickly children react to stimuli but also impacts the level of activity that occurs in the cerebral cortex during action monitoring. "I like to … [Read more...]

More than one-third of people in the US are obese. Obesity and its related health problems -- including high blood pressure, high cholesterol, diabetes, insulin resistance, and belly fat -- affect so many, yet effective treatments are very few.

Dartmouth researchers studying rats have discovered that activation of designer neural receptors can suppress cravings in a brain region involved in triggering those cravings. The study is the first to systematically show how designer brain receptors and designer drugs work together to change how cues for food stimulate motivation. The findings, which may help scientists to … [Read more...]

In 2013, 42 million infants and young children worldwide were overweight or obese. If current trends continue, that number will increase to 70 million by 2025, according to the World Heath Organization. It's not just genes that are the cause: socio-demographic and environmental elements are also contributing factors. Lower socio-economic status, living in neighbourhoods that … [Read more...]
