Just One Night of Sleep Deprivation?

Adequate sleep could be the unsung hero of obesity treatment.

When thinking about treating obesity, most of us think of diet and exercise. However, sleep loss increasingly appears to be an important factor. Dogs deprived of sleep for one night suffered a 33% drop in insulin sensitivity. The same 8 dogs had a 21% drop when fed a high-fat diet for 6 months. These results cannot be applied to humans--but poor sleep may yet be linked with overweight, obesity and type 2 diabetes.

PositiveTip: Remember, most adults need 8+ hours per night.
