burn fat through exercise

Is it better to exercise in the morning or before you go too sleep?
Someone told me it was better to exercise in the morning because it you burn fat through the day, but another person told me it was better to exercise before you go to bed because then you burn off extra fat while sleeping. so which one it better?
Your friend is right. Your metabolism stays at a high for about 12 hours after you exercise. Working out in the mornings and eating the majority of your calories before 2 keeps your metabolism in high gear.
