Night owls are more likely to gain weight than early birds.
That’s the gist of research by the Mayo Clinic. Which found that night owls eat about 550 extra calories a day – mostly junk food between the hours of 10PM and 4AM. That’s because night owls tend to sleep about 80 minutes less per night than early birds… which messes with their hunger and “I’m full” hormones – making them more likely to overeat.
