A lack of sleep promotes weight gain by increasing caloric intake, altering food preferences toward certain macronutrients, and modifying the way the body stores energy (fat versus muscle).

The influence of sleep on metabolism is a widely documented field. A meta-analysis published in the European Journal of Clinical Nutrition confirms that sleep deprivation leads to a significant increase in daily caloric intake. Regarding macronutrients, studies show an increased tendency toward foods rich in carbohydrates and fats, linked to a dysregulation of hunger hormones (ghrelin and leptin). Research, particularly randomized controlled trials (RCTs) such as those published in Annals of Internal Medicine, also supports that sleep deprivation reduces fat mass loss during a caloric deficit, favoring muscle mass loss. The claim that the distribution of storage is 'disrupted' is scientifically consistent with these metabolic observations. The creator synthesizes established physiological mechanisms here without overstating their reach.
