That being said, if the body contains fewer carbohydrates before beginning a workout, then the body will have fewer carbohydrates to burn for energy before needing to burn fat for energy. However the very nature of the calories created by the processing of these different materials create a different kind of energy.

There is a significantly larger amount of energy created by the processing of carbohydrates vs fats. Which means the workout feels more tiring than it would feel had the individual engaging in it had eaten before working out.

More importantly than whether to engage in cardio before or after (which I think the majority consensus would be before) its what kind of cardio. While distance running requires a lot from the lungs, it doesn't burn very much energy/sec.
This only works in the morning when you wake up right? Im sure later in the day would be bad..

Im on the eliptical for 30 minutes and my heart rate is usualy around the 155-180 level and im 20 years old and i weigh about 180..
