Leptin is a hormone produced by fat cells that plays an important role in regulating hunger and metabolism. Low levels of leptin have been associated with increased appetite and weight gain, while high levels have been linked to decreased appetite and weight loss. Therefore, changes in leptin concentrations can influence weight, body fat, and response to dieting. Serotonin and dopamine are neurotransmitters that play a role in mood, reward, and pleasure, but their connection to weight is less established. Oxytocin is a hormone that plays a role in social bonding and reproductive functions, and its link to weight is still being studied.
