Penn researchers awarded $3.75 million to study how mealtimes influence human health

(University of Pennsylvania School of Medicine) Disrupting sleep-wake cycles from a predominantly daytime to a delayed eating lifestyle, -- i.e., skipping breakfast and making lunch the first meal of the day, plus eating late dinner, disrupts the body's natural circadian (24-hour) rhythm, the cycle that tells us when to sleep, wake up, eat, and influences hormones and other functions.
