Should We Sleep More to Burn Unwanted Fat?
Are you trying your best to eat healthy, and exercise, but still not losing weight?
The new research suggests that sleep patterns affects body weight control and that sleep deprivation has consequences not only for how many calories we consume but also for how much fat we burn off.
Many studies have found a relationship between how long we sleep for and being overweight, suggesting that sleep deprivation can lead to weight gain, not only by escalating appetite, but also by slowing metabolism.
The latest research from the German Universities Tubingen and Lubeck and Uppsala University in Sweden has investigated the effect of short term sleep deprivation on food cravings as well as on physical activity and energy used by the body.
The researchers have found that sleep duration may be an significant regulator of body weight and metabolism. Participants with sleep loss had reduced leptin and elevated the amount of the “hunger hormone” ghrelin. These differences in leptin and ghrelin are likely to boost appetite, possibly explaining the increased BMI observed with short sleep duration.
Furthermore, staying awake for one full night decreased the amount of energy used by the body when sleeping. This shows that sleep plays a major role in determining daytime energy production. It also indicates that sleep deprivation increases hunger and slows down metabolism. This is why chronic sleep deprivation leads to weight gain.
While more research needs to be done before sleep improvement can be touted
as a reliable obesity and diabetes cure, latest research suggests that sleep is involved in the balance between the amount of calories we eat and the amount burn up through metabolism and exercise.
The research was funded by the German Research Foundation (DFG).
The ideal amount of sleep for adults recommended by The National Sleep Foundation is seven to nine hours every night.
