Lack of Sleep Makes You Crave Sweets

Not getting enough sleep can have negative effects on your health. They can be weakened immune system, increased risk for diabetes, heart disease and poor coordination. Add one more increased craving for sweets.

Insufficient sleep is linked to increased caloric intake and to obesity.

In a randomized crossover study, 24 people slept for either five or eight hours per night for three consecutive nights.  The shorter sleep increased objective sweet-taste preference and intake of calories and carbs at the buffet meal.

While shorter sleep was associated with an overall increase in caloric intake, it affected different individuals very differently. Some ate a lot more (up to +679 kcal), but some actually ate less (down to −261 kcal).

One of the simplest thing you can do to improve your health is to sleep 7-8 hours a day.
