    fasted cardio bad?


    I have seen many people say that they do IF and cardio. What I am wondering is if that is bad for muscle growth/ maintaining muscle. And how effective it really is at burning fat. Expecially if you are already on a low carb diet. Since if your body is on a low carb diet and lifting your body will use that glucose to fuel your muscles. So there will already be a low amount of glucose in ones blood stream. And if the body has too low of blood glucose levels the pancreas will make glycagon to increase blood glucose levels and it will do it by breaking down glycogen. So my question is... would IF and cardio be detrimental to muscle if on low carb diet? Hope I didn't sound like a jack ass right there. Lol

    1) there's not as much benefit doing it fasted if you're already on a low carb diet

    2) intensity is the key factor. LISS in a fasted state is fine as your body will use primarily fat as fuel; anything moderate to high intensity, some protein or BCAAs beforehand would be a wise idea.

    I personally started doing a low carb diet approx 2 months ago, going from 250g/day to 140g/day. The 1st month I did JUST the low carb diet and saw some fat loss. Then I started fasted cardio in the AM the 2nd month. I noticed a dramatic increase in fat burning when I started the 2nd month, while maintaining my strength and judging by the mirror, size as well. I do take BCAAs after as well. Hope this helps!

    If your cutting carbs and doing IF your obviously trying to cut which you will most likely lose some muscle during a cut anyway weather fasted cardio or not.

    Bcaas will help preserve the muscle you have.

    I myself have not done IF, and correct me if im wrong but i understand The idea of cardio fasted is you are already in a fasted state where your body is using the fat for energy so you are burning fat during that fasted state, so to add the cardio in to that fasted state you will again burn more fat.

    Then you eat your target calories in you eating window weather.

    As posted it would depend on intensity. Low intensity would help where high intensity would actually be more detrimental.

    My best answer is....what ever works for you is best. If you diet 12 to 16 weeks you shouldn't be at much of a muscle loss. Refeeds also prevent or help this.muscle memory does the rest. Cut,then maintain and get your size back.

    i used to major in the minors. then i stopped after working out with guys much stronger than me and they just pushed harder. whether it was lifting, eating, or recovering, they did it harder than anyone else.

    this included me switching to a lean gains type diet where i eat between noon and 8. on sundays i join the guys for a 3-4 hour strongman training session that starts at 10am. so ya, i havent eaten in 14 hours and wont eat for at least 4 if not 5 hours more. that makes upwards of 18 hours without food. doesnt kill. i keep getting stronger. and the more fat i have in my diet the better i train those days even while waiting that long without food.

    the human body is an amazing machine that can adapt and deal with adversity quite well. if we were to believe all the the broscience on exercise it really appears that the human body is a giant Pu$$Y. and it makes you wonder how we have survived as a species.

    the science is cool and great and stuff. but dont get so caught up in the details that you forget that training harder, eating harder, and recovering harder will get you further then most anything.
    you can call me "ozzie" for short.

    It is good to read. Proper exercises and regular diet help to get your size back. But e-regular exercise and diet plays main role to increase so many problems that effect on cardio and your digestion.

    This is true and i am totally agreed with this statement. Fast cardio is bad for health so it is good to do cardio slowly. Too much fast cardio effects on our muscles so we should avoid it.

    Ok, quick question, were you doing any cardio at all prior? Or did you just simply inserted "cardio" overall? Because if it is the later, then there may be an argument that it was just for the fact your expenditure went up.

    Aerobic exercise in a fasted state is fine
    Anaerobic exercise in a fasted state is questionable but I tend to lean towards it is fine as well based off anecdotal evidence.

    I understand the mentality here. Always want the edge, the advantage. But honestly time spent worrying about such minute details could be better spent perfecting aspects like nutrition and training that have a much larger body of research regarding what works and what doesn't

    Wouldn't researching the effects of fasted x not fasted workout fall under the "larger body of research regarding what works" category?

    Haha yeah. I guess what I meant to say were things that have a considerable amount of research backing. Fasted training isn't up near the top

    haha, true

    I've always been intrigued by the fasted cardio, and enjoy as a change of pace. Not sure if it works better or not, but I do try to squeeze in a couple here and there too. Lower intensity, will leave the long runs for when I have at least had some sort of meals
