What (and whether) to eat before bed is framed as a lever for avoiding hunger-driven wake-ups without disrupting sleep, plus a warning about a sleep-deprivation/craving feedback loop.
Recommended pre-sleep snack (if needed): roughly 50% complex carbohydrate + 50% lean protein. Examples: whole-grain cereal with milk, cottage cheese with fruit, whole-wheat crackers with peanut butter, nuts with yogurt and berries. The carb/protein balance is meant to prevent hunger from waking the sleeper without the digestive/metabolic disruption of a heavier meal.
Foods to avoid before bed: alcohol, caffeine, heavy or fried meals, tomato-based foods (acid reflux risk), and sugary carbohydrates.
Craving feedback loop: sleep-deprived people tend to crave exactly these harmful foods (high-sugar, high-fat), so insufficient sleep and poor pre-sleep food choices reinforce each other — a claimed pathway from sleep debt to weight gain, connecting Sleep Debt Accumulation and Banking to longer-term metabolic/body-composition outcomes.
Concrete snack pairings that fit the ~50% complex-carbohydrate / 50% lean-protein formula: whole-grain cereal with milk, cottage cheese with fruit, whole-wheat crackers with peanut butter, or nuts with yogurt and berries. These slow-digesting combinations are preferred over sugary or fried food eaten close to bedtime.
