A calorie at 7:59 p.m. is the same as a calorie at 8:01 p.m. Whether you’re eating at 7:59 p.m., 8:01 p.m., or in the middle of the night, it really doesn’t matter. Instead, consider each of the 24 hours in a day to be equal in terms of importance… or simply the number of calories you eat in a day.
