""If cortisol is high and serotonin is low, you'll seek carbs and fats, but really heavy duty on the simple carbs -- sugar-based sweets like chocolate bars," Peeke says.

If cortisol is way up but serotonin is relatively normal, a woman is more likely to crave a fat-carb combo without a huge sweet component, such as a bagel laden with cream cheese, Peeke says." - Lisa Brewster from Mento
