I read an article from Health Magazine at the gym this morning about the issue of if you can stay up late and still lose weight. Basically the theory was that if you don't eat after 8 p.m. pm your body will use up its glycogen stores and start burning fat while you sleep. I've always heard that it doesn't matter when you eat it's the total number of calories in and out that matter. But this theory of a night-time fast to allow your body to use up the stored glycogen and then start burning fat does make sense. I also found an article from getfitwithkevin that explained our bodies start to slow down after five pm to prepare us for a good night's rest so if we're eating after 7 or 8 p.m. that food won't be used as energy but stored as fat to use later. This theory also makes sense to me; that food we eat late at night is being processed and then stored instead of utilized. If you add that theory to the earlier one of using a nighttime fast to store fat, it presents a pretty strong argument to not eat late at night.
What do you think?
