“Although recent findings suggested that obese individuals may experience less pleasure when eating, and therefore eat more to compensate, this is the first prospective evidence for this relationship… Using brain imaging and chocolate milkshakes, scientists have found that women with weakened ‘reward circuitry’ in their brains are at increased risk of weight gain over time and potential obesity. The risk increases even more for women who also have a gene associated with compromised dopamine signaling in the brain.” (Science Daily)
