Which is similarly why a diet high in carbohydrates can lead to your body storing more fat. It's easier for your body to turn the carbohydrates into energy than it is to turn the fat into energy. So when it gets both, it stores the fat for leaner times (less energy abundance) and turns the carbs into glucose for energy. It seems like the more we learn about high fat low carb diets, the more it seems that our body was built to use fat as its main energy source.
