We know sleep influences many things in life, but caloric intake? Indeed. A study at St. Luke’s-Roosevelt Hospital demonstrated that women who only got 4 hours of sleep/night ate 329 more calories and an astounding 31 more grams of fat than when they slept well. But it doesn’t end there. Night owls, even when sleeping 7 hrs, ate an average of 248 more calories than those who went to bed early (Northwestern University study).
