Dietary preference for fat may increase risk for obesity. It is a complex behavior regulated in
part by the amygdala, a brain structure involved in reward processing and food behavior …

The orexin peptides promote hedonic intake and other reward behaviors through different
brain sites. The opioid dynorphin peptides are co-released with orexin peptides but block …

Binge eating disorders are characterized by discrete episodes of rapid and excessive food
consumption. In rats, giving intermittent access to sweet fat food mimics this aspect of binge …

The pentapeptides methionine-enkephalin and leucine-enkephalin belong to the opioid
family of peptides, and the non-opiate peptide adrenocorticotropin hormone (ACTH) to the …

from animal studies suggests central opioids and dopamine have prominent role on appetite …

The mesolimbic reward pathway is activated by drugs of abuse and palatable food, causing
a sense of pleasure, which promotes further consumption of these substances. Children …
