A new study measures the brain activity of healthy, normal weight adults aged 22-26 to determine the effects of a lack of sleep on appetite signaling in their brains. The study showed that a lack of sleep causes brain signaling to significantly increase in areas associated with food acquisition. In other words, if you don’t sleep enough you are much more likely to eat too much food and gain weight.
This study helps prove the point of many earlier studies showing that a lack of sleep, even in children, is associated with weight gain. This study adds to the evidence, showing that cravings relating to addiction and reward come in to play when you don’t sleep enough.
Food acquisition is required for survival. When your body is tired, as in the case of a lack of sleep, your cells think they need more energy. This can trigger powerful subconscious urges to eat.
