Cortisol is a stress hormone. Periods of
fasting or excessive caloric restriction,
along with lack of adequate sleep or too
much stress, may contribute to
chronically elevated cortisol levels.
Chronically elevated cortisol levels
increase blood sugar, which may
contribute to insulin resistance and
promotes weight gain in the abdominal
region, a component of metabolic
syndrome.
