Yes, there is a connection between weight gain and a lack of sleep. It appears that it causes a hormone imbalance, more specifically leptin and ghrelin which trigger the hunger switch on and off.
About1,000 volunteers reported the number of hours they slept each night. Doctors then measured their levels of ghrelin and leptin, as well as charted their weight.
The result: Those who slept less than eight hours a night not only had lower levels of leptin and higher levels of ghrelin, but they also had a higher level of body fat. What's more, that level of body fat seemed to correlate with their sleep patterns. Specifically, those who slept the fewest hours per night weighed the most.
