How do neurotransmitters affect appetite regulation?
| Step | Action | Novel Insight | Risk Factors |
|---|---|---|---|
| 1 | Neurotransmitters such as dopamine, serotonin, and norepinephrine play a crucial role in appetite regulation. | Dopamine levels in the brain affect the reward and pleasure centers, which can lead to overeating. | Overconsumption of high-fat and high-sugar foods can lead to dopamine resistance, making it harder to feel satisfied with normal amounts of food. |
| 2 | Serotonin levels in the brain affect mood and can influence food choices. | Low serotonin levels can lead to cravings for carbohydrates and comfort foods. | Overconsumption of carbohydrates can lead to insulin resistance and weight gain. |
| 3 | Ghrelin is a hormone produced in the stomach that stimulates hunger. | Ghrelin levels increase before meals and decrease after meals. | Chronic stress can lead to increased ghrelin production, leading to overeating and weight gain. |
| 4 | Leptin is a hormone produced by fat cells that signals satiety to the brain. | Leptin levels increase as fat stores increase. | Obesity can lead to leptin resistance, making it harder to feel full and leading to overeating. |
| 5 | Gastrointestinal hormones such as cholecystokinin (CCK) and peptide YY (PYY) are released in response to food intake and signal satiety to the brain. | CCK and PYY levels increase after meals and decrease during fasting. | Eating too quickly can lead to decreased CCK and PYY levels, leading to overeating. |
| 6 | Neuropeptide Y (NPY) and orexins/hypocretins are neurotransmitters that stimulate hunger. | NPY levels increase during fasting and decrease after meals. | Chronic sleep deprivation can lead to increased orexin/hypocretin production, leading to overeating and weight gain. |
| 7 | The melanocortin signaling pathway in the brain plays a role in appetite regulation. | Activation of the melanocortin pathway leads to decreased appetite and increased energy expenditure. | Mutations in genes involved in the melanocortin pathway can lead to obesity and overeating. |
| 8 | The endocannabinoid system in the brain plays a role in appetite regulation. | Activation of the endocannabinoid system can lead to increased appetite and food intake. | Chronic cannabis use can lead to overeating and weight gain. |

Common Mistakes And Misconceptions
| Mistake/Misconception | Correct Viewpoint |
|---|---|
| Gut hormones and cognitive hormones are the same thing. | Gut hormones and cognitive hormones are two different types of hormones that have distinct functions in the body. Gut hormones, such as ghrelin and leptin, regulate appetite and digestion while cognitive hormones, such as dopamine and serotonin, affect mood, cognition, and behavior. |
| Only one type of hormone is responsible for regulating eating behavior. | Both gut hormones and cognitive hormones play a role in regulating eating behavior. While gut hormones signal hunger or fullness based on physiological needs like nutrient levels in the blood or stomach distension, cognitive factors like stress or emotions can also influence food intake through changes in neurotransmitter activity. |
| Hormones only affect physical sensations related to hunger/fullness but not psychological aspects of eating behavior. | Hormones can impact both physical sensations related to hunger/fullness as well as psychological aspects of eating behavior such as motivation to eat certain foods or feelings of reward after consuming them. For example, dopamine release in response to palatable foods can reinforce overeating behaviors even when someone is already physically full from a meal due to its rewarding effects on the brain’s pleasure centers. |
| Hormonal imbalances always lead to disordered eating behaviors. | While hormonal imbalances may contribute to disordered eating patterns (e.g., insulin resistance leading to increased cravings for sugary foods), they do not necessarily cause them outright without other contributing factors like environmental cues or emotional distress present. |
