Sleep Influence on Energy Balance and Weight Management

Sleep duration and quality are pivotal regulators of energy homeostasis and weight control. Insufficient or fragmented sleep disrupts the balance between energy intake and expenditure by altering hormonal signals, appetite regulation and metabolic processes. Short or poor sleep elevates ghrelin and suppresses leptin, driving increased hunger, cravings for energy‐dense foods and greater caloric consumption, while energy expenditure remains largely unchanged. Habitual sleep restriction has been linked to higher body mass index, greater central adiposity and impaired dietary choices, contributing to the global rise in obesity. Conversely, extending sleep duration in habitual short sleepers can reduce free sugar intake and promote a negative energy balance, offering a non‐pharmacological strategy for weight management. These findings underscore the interdependence of sleep, diet and metabolism and highlight practical interventions that integrate sleep hygiene into obesity prevention and treatment programmes.

Research from Nature Portfolio

Controlled investigations into the metabolic consequences of sleep reduction have revealed that acute sleep restriction diminishes core body temperature without significantly altering total energy expenditure, yet it enhances subjective hunger and prospective food consumption. Hormonal assessments indicated reductions in peptide YY and elevations in hunger ratings after several nights of restricted sleep, pointing to a physiological drive towards increased intake. In parallel, longitudinal studies have demonstrated that individual responses to repeated sleep restriction exhibit trait‐like stability: some participants consistently gain weight and consume more calories during sleep loss, whereas others remain resilient. This phenotypic vulnerability highlights the need for personalised approaches to predict and mitigate the effects of insufficient sleep on energy balance.
