There is a direct correlation between chronic sleep deprivation and obesity. Whether that is because of the resulting hormone imbalance, increased cravings for sugar and starchy foods or decreased efficiency of body processes. A study was conducted over 16 years and found that women who sleep less than 5 hours/night were 15% more likely to be obese (BMI > 30). Conversely, too much sleep is also linked to obesity due to reverse causation.
