“Overconsumption….may occur in an attempt to increase brain reward in less responsive systems”

Standard

“Women who possess genetic modifications associated with low activity of the reward neurotransmitter dopamine in the brain when they imagine eating appetizing foods are more prone to weight gain.

  • Women who had lower activity in food reward regions of the brain and who had genetic modifications associated with lower dopamine activity showed the greatest weight gain after one year
  • People who experience blunted reward from food may compensate by overeating, increasing risk for unhealthy weight gain.””
