Severe sleep loss can increase food intake; sustained mild restriction can strain metabolic health, while dietary choices may help interrupt the sleep and diet cycle.
Insufficient sleep can shift hunger and satiety signaling in men and women in different ways, which can contribute to higher calorie intake.
Eating diets high in fiber is associated with deeper, more restorative slow-wave sleep, whereas higher saturated fat intake is linked to less deep sleep and higher refined carbohydrate intake to more nighttime arousals.
After six weeks of sustained mild sleep restriction, St-Onge found increased insulin resistance and reduced insulin sensitivity, especially in postmenopausal women; blood pressure also rose.
