    I've gone through phases of doing that (mostly from poor time management skills rattler than purposefully not eating). I haven't noticed any difference except I have less energy to do the workout! Likewise, if I eat too much I'm sluggish... So I like a light snack beforehand :)

    In terms of the science behind it,I believe the theory is that if you haven't eaten, your body will burn more fat than if you'd eaten a bagel and you're just burning off those carbs. Makes sense to me, but I'd rather feel good doing it than feel like crap and burn more fat... Seems like the inefficiency in energy levels will shoot you in the foot in the end.... But I'm sure others bodies operate on low food better than mine.

    In conclusion: it depends. :)

    I run 6 days a week in the morning. I can't have anything to eat before hand or I get sick. I've tried just having a banana and I still got sick. But everyone is different, do what works for you.

    the banana is possibly the most over rated food out there next to oatmeal. just sayin. everytime I see "banana" this gets in my head.

    SupposedLy early morning cardio with no food in your system but maybe a cup of coffee optimizes fat burning.
    The idea being there are reduced glycogen stores to use for eneRgy and you body will use fat sooner for the cardio re
    Quirements.

    Another way to simulate this scenario later in the day after youve eaten is do your weightlifting first, which will use up the glycogen stores.
    If you follow that with a cardio workout, again your body will turn to use the fat stores sooner for energy for the cardio.

    In the mornings definitely eat something before weightlifting.
    Its not as important and maybe even preferable to not eat anything before morning cardio.



    Pretty sure that this and my earlier post are not myths.

    I don't know about cardio but I always do my lifting before I eat my first meal of the day and it has never been a problem for me.

    "The best time to do cardio will be whenever it will most consistently get done. If that’s first thing in the morning, fantastic. If not, also fantastic. It’s more important in this situation that it gets done than when it gets done."

    That's how I've always done it. I get sick to my stomach if I work out with food in it.

    That sounds good too, I like to lift at night so chasing it with some cardio seems like a good idea if I don't do it in the morning. Thanks for this

    work out EVERY MORNING as soon as I get up....sometimes I chug a cup of coffee, but usually just my trusty water bottle....I have never even though about the fact that it might be 'fasting' b/c of the not eating all night....hmmm... interesting....although I feel like I am burning.....I have maintained for quite a while now, so I'm a little sketchy to say that workouts are somehow less efficient.....no expert though

    Summing Up the Research Findings

    • At low intensities (25-50% VO2 max), carbs during exercise reduce fat oxidation compared to fasted trainees.
    • At moderate intensities (63-68% VO2 max) carbs during exercise may reduce fat oxidation in untrained subjects, but do not reduce fat oxidation in trained subjects for at least the first 80-120 minutes of exercise.
    • Carbohydrate during exercise spares liver glycogen, which is among the most critical factors for anticatabolism during hypocaloric & other conditions of metabolic stress. This protective hepatic effect is absent in fasted cardio.
    • At the established intensity level of peak fat oxidation (~63% VO2 max), carbohydrate increases performance without any suppression of fat oxidation in trained subjects.

    I work out on an empty stomach sometimes and have no problems, but if I have eaten, I cannot workout for at least an hour and 1/2 or I will be pukey. I think everyone is different.
