Danyele, if you're increasing your workouts you should also be increasing your food, in particular your protein. It could be that you are engaging in excessive cardio - too much of a good thing doesn't make for a better thing. I know that when I tried doing cardio 6 days a week I stopped losing fat - my body could not keep up with the stress/cortisol and I couldnt eat enough to sustain fat burning.

It flies in the face of conventional wisdom, but adding extra cardio to burn more fat when you're already working out quite heavily isn't usually the answer. When was the last time you had a break from working out?
