We’ve heard that eating at night leads to weight gain… even if you’re not eating any more than you normally do. So why is that? According to the Autonomous University of Chile, it’s because our bodies have adapted to burn more energy during the day. So as the sun sets, our metabolism naturally slows down, helping us prepare for sleep. That means we’re not processing food as efficiently. And in a study of 5,000 people, those who ate after 8pm had waists that were two inches bigger – even though they ate the same number of calories, and had the same activity levels as those who ate earlier in the day.
