No reallyI dont get itexplain some more!
  • Many of consequences of BED overlap with stress
  • Type II Diabetes due to inactivity and fat
    surplus
  • High BP heart beats faster by increasing SNS
    (which occurs during the Initial Stage of stress)
  • Trouble sleeping
  • Stress shuts down digestion during stressor, so
    why are we hungry? (hyperphagic vs hypophagic)
  • CRH suppresses food intake
  • ACTH ?GCs increase appetite (Leptin)
  • Interesting!
  • Soconstant stressdecrease appetite repeated
    intermittent stressincrease appetite
  • GC hypersecreters eat more after stress crave
    sweets but dont when NOT stressed (normally
    restrained eaters more likely to overeat because
    of stress)
  • Due to operant conditioning that starchy foods
    make us happy and less stressful?
