The principle is based on the idea that active digestion maintains the sympathetic nervous system, which can interfere with nocturnal recovery processes. Observational studies and randomized controlled trials (RCTs) indeed suggest that late eating is associated with circadian rhythm disruption and higher nocturnal blood pressure (Journal of the American Heart Association). Scientific literature confirms that nocturnal 'dipping' (the natural drop in blood pressure during sleep) is an important marker of cardiovascular health. However, the claim that 3 hours is a precise universal threshold is a simplification, as the speed of digestion varies depending on the meal's composition (fiber, fat, protein). While the link between late meals and metabolism is supported by solid data, the direct impact on sleep quality is sometimes nuanced in clinical studies depending on the individual. It is accurate that limiting late-night caloric intake promotes a state of physiological rest more conducive to recovery.

What’s uncertain
Evidence is modest and mixed, with no well-established universal cutoff. Individual responses vary; the reliable guidance is to avoid large heavy meals right before bed, not to fear all evening food.
