At the University of Chicago’s General Clinical Resource Center researchers followed 10 overweight, but healthy participants aged 35 to 49 who according to body mass index were considered overweight. The participants where given an individualized, balanced diet that reduced their calories by 10% of what was needed to maintain their weight without exercise (roughly 1,450 calories per day).
Each participant was studied twice: the first time studied participants sleep on average 7.5 hours over a fourteen day period, the second time for only 5.5 hours over a fourteen day period.
The researchers found that when sleeping less it reduced the participants fat loss by 55%. When participants got adequate sleep they also found that their ghrelin levels were lower. High ghrelin levels reduce energy expenditure, increase hunger and promote fat retention.
In conjunction with Stanford University the University of Chicago took this a step farther by then looking at the leptin (leptin sends a signal to your brain telling it you are full) and ghrelin levels in 12 healthy men after being subjected to two days of adequate sleep and two days of sleep deprivation. They found that when sleep was restricted leptin levels went down and ghrelin levels went up. Thus, resulting in increased appetites and an inability to get full. They also found that the participants had an increased craving for high carbohydrate, calorie dense food.
Standard and the University of Wisconsin then took this even a step farther. They had 1,000 volunteers report the number of hours they slept each night. Then measured their leptin and ghrelin levels and charted their weight. Not surprisingly they found that those who slept less had lower leptin levels, higher ghrelin levels, weighted more, and had a higher level of body fat.
If you’ve been dieting and exercising, but having trouble losing weight or not happy with your progress check you sleep. We each need between 7-8 hours a night. Even if you sleep less and don’t think you need it you probably do. Many of us are used to functioning with a lack of sleep that we no longer remember what it feels like to be fully rested and recharged. Sometimes we just don’t know how bad we felt until we feel good again.
