When is the best time to eat dinner? Well if you want to sleep through the night you should finish dinner at least 3 hours before you plan to go to bed.
Sleep medicine specialist, Peter Polos, M.D., Ph.D., FCCP, FAASM, says quote, "This allows adequate time for digestion, thereby reducing any possible disruption to sleep caused by poor digestion."
Eating earlier than that won't help because your blood sugar can dip if you go to bed hungry and that can wake you up.
