The Relationships Among Sleep, Nutrition, and Obesity

Abstract

Obesity is associated with an array of adverse physiological, psychological, and social consequences. Tackling obesity remains difficult, given the challenges of maintaining positive behavior changes. Obesity occurs from persistent positive energy (excessive energy intake with insufficient counteractive energy expenditure), but several biological, psychological, and environmental factors influence energy balance. It has recently emerged that sleep duration is an important factor that impinges on energy balance and could be a potential overlooked behavior predisposing to obesity. We highlight and review the recent evidence surrounding sleep in relation to obesity from epidemiological studies to experimental work.
