What are the effects of high-carb versus low-carb diets on sleep quality and duration?

High-carb versus low-carb diets can have different effects on sleep quality and duration. High-carb diets, particularly those including complex carbs, may promote better sleep by increasing the availability of tryptophan, an amino acid that aids in serotonin and melatonin production. In contrast, low-carb diets might disrupt sleep patterns for some individuals, potentially leading to difficulties falling or staying asleep due to altered hormonal balances and energy levels.
