Common sense might say that you have a good chance of burning more fat in the morning, and there is some evidence to support those theories. For one, your levels of cortisol are higher in the morning, and cortisol is the hormone that helps to metabolize fat into energy. Your body wakes up a fat-burning machine, in other words. In addition, while you are asleep your body uses up the leftover carbohydrates that are still in your system, leaving you with very little except fat reserves for energy in the morning.
According to BodyBuilder.com, there have been several studies conducted that show people can burn up to 20% more fat if they work out in the morning before consuming any food. Sounds primed to go, right? Unfortunately, that’s not the whole story.
