Evidence of behavioral, biological similarities between compulsive overeating and addiction
Does yo-yo dieting drive compulsive eating? There may be a connection. According to Boston University School of Medicine (BUSM) researchers the chronic cyclic pattern of overeating followed by undereating, reduces the brain's ability to feel reward and may drive compulsive eating. This finding suggests that future research into treatment of compulsive eating behavior should focus on rebalancing the mesolimbic dopamine system--the part of the brain responsible for feeling reward or pleasure. (2019-10-17)

People eat more when dining with friends and family -- Study
People eat more with friends and family than when dining alone -- a possible throwback to our early ancestors' approach to survival, according to a new study. This phenomenon is known as 'social facilitation'. (2019-10-04)

Estimating calorie content not clear-cut for all -- Otago study

Curbing your enthusiasm for overeating
Signals between our gut and brain control how and when we eat food. But how the molecular mechanisms involved in this signaling are affected when we eat a high-energy diet and how they contribute to obesity are not well understood. Using a mouse model, a research team led by a biomedical scientist at UC Riverside has found that overactive endocannabinoid signaling in the gut drives overeating in diet-induced obesity by blocking gut-brain satiation signaling. (2019-06-11)

(2019-03-24)

Review suggests a reciprocal relationship between obesity and self-control
In a review published Feb. 26 in the journal Trends in Cognitive Sciences, researchers explore the age-old chicken-or-the-egg conundrum but this time looking at whether obesity reduces self-control or if reduced self-control leads to obesity. The authors argue that the short answer is both, and it is largely due to activity in the prefrontal cortex, which is not only affected by our dietary choices, but can also influence it. (2019-02-26)
