Elevated reward response to receipt of palatable food predicts future weight variability in healthy-weight adolescents
body weight fMRI obesity weight fluctuations weight variability

2018/11/13
Background: Both an elevated brain-reward–region response to palatable food and elevated weight variability have been shown to predict future weight gain.
Objective: We examined whether the brain-rew...

Background: Short-chain fatty acids (SCFAs), metabolites produced through the microbial fermentation of nondigestible dietary components, have key roles in energy homeostasis. Animal research suggests...

Numerous studies have found that obese compared with lean individuals show greater response of brain regions implicated in reward [e.g., orbitofrontal cortex (OFC), striatum, amygdala] when viewing im...

Many parents report, anecdotally, that their child came into the world with a big appetite. They claim this drive to eat was there since birth, as if it were nature’s hand at play. Indeed, questions f...

Background: Neural responses to rewarding food cues are significantly different in the fed vs. fasted (>8 h food-deprived) state. However, the effect of eating to satiety after a shorter (more natural...
