15) If You Don't Eat Before A Workout, You'll Burn More Fat

No scientific studies have proven this to be true. While exercising fasted could force your body to use more fat for fuel (when your glycogen stores are depleted), it has not been shown to burn more fat overall. Not only this, but it depends on the activity you're doing, the duration and intensity. If you want to run 10 miles, you'll need quick-digesting carbs for energy. If you're doing a moderate-intensity 30-minute workout, you don't have to eat beforehand. However, if you don't eat before, it is imperative to eat afterward, to replenish your stores and get your body the repairing nutrients it needs. Otherwise, your fitness goals may suffer.
