But a lack of sleep may make weight loss and weight control more difficult by altering our metabolism, as well as our eating and activity patterns. Keep in mind that maintaining a healthy weight affects more than your appearance.
The American Institute for Cancer Research advises everyone to limit weight gain in adulthood to less than 11 pounds to reduce cancer risk.
The latter group was almost twice as likely to be overweight. Children sleeping less than eight hours a night were almost three times as likely to be overweight.
A lack of sleep may change hormone levels and thus influence weight gain. For instance, higher levels of insulin -- a condition known as insulin resistance -- have been linked to a shortage of sleep.
Since insulin promotes fat storage, as well as controls blood sugar, extra insulin could make weight loss more difficult. Further research needs to confirm any hormonal changes. But even without affecting hormones, sleep deprivation can promote weight gain by changing our behavior.
Furthermore, the most appealing foods when we feel low on energy are often sweets or refined carbohydrates with low nutrient density, like cookies. If sleep deprivation promotes insulin resistance, overconsuming these types of carbohydrates worsens the problem.
Tired people may burn fewer calories, too, because they are too fatigued to exercise. Or if they do manage to exercise, they work out less intensely than usual.
For example, a rested person may walk two miles in a half-hour. Someone fatigued will probably go a much shorter distance in the same time. The tired person would burn fewer calories, despite walking just as long.
