Lack of Sleep Leaves Men Hungrier, Prevents Women Feeling Full
How much sleep do you get in a given night? New research published in SLEEP found that sleeping more at night may result in reduced food consumption. However, men experience an increased appetite while women feel less full. A product of hormonal reactions to sleep, both men and women have a tendency to eat too much during periods of shorter sleep.
The study investigated 27 males and females, each group containing individuals of average weight between 30 and 45 years old. A "short" sleep cycle was considered to be four hours, while "habitual" sleep was a nine hour sleep. The researchers were surprised that lack of significant sleep had such a profound impact on glucose and insulin, and were surprised by the sex differences in certain hunger-stimulating hormones.
