Abstract	Intermittent fasting (IF), a structured pattern of timed eating and fasting, has gained popularity for its metabolic and physiological benefits. Recent studies have explored the possible interactions between intermittent fasting and sleep, recognizing that the timing of food intake can influence the body’s circadian rhythm. This review aims to examine the impact of intermittent fasting on sleep parameters such as sleep quality, duration, insomnia severity, and the risk of obstructive sleep apnea. By consolidating findings from controlled human trials, it highlights how intermittent fasting may contribute to improved sleep by promoting weight loss, hormonal regulation, and alignment with natural circadian cycles. However, the evidence remains mixed, with some studies showing minimal or no significant change in sleep outcomes. The review also emphasizes that while intermittent fasting may support better sleep through improved metabolic health and reduced inflammation, its effectiveness can vary among individuals. A deeper understanding of this interplay could aid in formulating dietary strategies that support both metabolic and sleep health. Further well-designed clinical trials are warranted to establish clearer causal relationships and practical applications.
