- Sensory input from the mouth (taste/texture) is relayed to the same cortical areas of the brain that receive satiety signals from the gut.
- Limbic processes such as the thalamus then integrate hypothalamic energy control signals, largely under the control of gut hormones such as ghrelin, leptin, insulin, and peptide YY.
- It is interesting to note, studies have shown the length of time between eating and satiety signal is much longer in obese individuals than in normal weight individuals.
- Also, obese children and adolescents were significantly less accurate in identifying bitter, savory, and salty tastes than normal weight children.
