The effects of Sleep loss on weight
10 overweight men and women were put on a low calorie diet.
1/2 the group sleep for only 5 1/2 hours per night
After 3 months the groups switched the number of hours they were allowed to sleep
Results the effects of sleep deprivation on human body
- no effect on weight lost
- all lost 55 per cent less fat
- 60 per cent more lean body ( mainly muscle) mass
- increase in appetite due to increase in hormone ghrelin
- lower metabolic rate
- increase tendency to gain weight or be obese
Both hormones leptin and ghrelin influence appetite. When you have sleepless night do you often feel that you cannot get enough food to satisfy your hunger the next day?no matter what you ate you never felt full or satisfied?
Sleep and sleep disruption do remarkable things to the body and some weight fluctuation can be attributed to the changes in the hormones leptin and ghrelin caused by stress.
Sleep in a quiet dark room and try to get 8 hours of solid uninterrupted sleep. Good dreaming!
