    this is kind of confusing now that ive been introduced to the concept of the body preferring to hoard fat for long term surivival and prioritizing muscle growth less... should you be taking protein with cardio too or something?

    It burns a little bit of both, depending on some factors. The bottom line is that it won't care at the end of the day unless you are trying to go down to competing bodyfat levels. Or unless you never end and wanna end up anorexic style.

    The body is designed to store fat to use later as fuel when other sources aren't availible. Your body will burn a higher percentage of fat as long as there is fat availible, thats what its for. The body is always breaking down and rebuilding.

    It depends greatly on diet and calorie levels, and if you weight train in addition to the cardio. If you're in a large calorie deficit, its going to burn muscle.

    The body burns fat most efficiently at 60 to 70% of your Vo2 max.

    You've got a couple options.

    Either do HIIT and boost your metabolism to create a slow burn for the rest of the day or do lots of walking.

    HIIT is going to be more efficient but it hurts.

    Setting a treadmill or stationary bike to fat burning mode is incredibly time consuming.

    It burns a higher volume of fat at higher levels of VO2 max, but it also diminishes glycogen stores quickly.

    depleting glycogen is beneficial for fat loss

    I always read/heard that because of that, low intensity cardio after lifting works well for fat loss. But I am still, so I can't confirm that's true. :o

    Would that also mean cardio first thing in the morning works as well?

    Longer durations at higher intensities is unnecessary but people that play with heart rate ranges rarely understand that, from my experience.

    Low intensity won't deplete glycogen which is why it burns a higher percentage of fat.

    fat is there to burn off. if you burn through so many calories that you move to your fat resevers then yes it will begin to break down SOME muscle. if you go home and have a carb/protein meal (protein shake and say brown rice) your muscle will rebuilt.


    unless your a doctor you will never understand the body and how it works fully. everyones acts differently. running and lifting are good. so is eating. but too much or little of either is bad.

    find your happy medium

    and this protein and especially the carbs go into ur muscle, not your fat?
    well in my case the process seems really slow...a span of months to see any gains or losses, so its hard to effectively spot changes in progress esp. if ur consistent 100% of the time. so im just trying to research some ground rules here..

    The fast and dirty method is to shoot for 60 to 70% of your maximal heart rate.

    Anything other than that will require some testing

    http://www.vo2maxtesting.net/

    HIIT is a really fast way of depleting your glycogen stores by running wind sprints or doing anything that requires 100% of your maximum effort for a one minute burst.

    Rest for 30 seconds

    Hit it again for a minute.

    Starting out, I can't recommend any more than 4 "bursts".

    You'll know if you're pushing yourself too hard.

    You'll lose inches in a week without changing your diet.

    If you have further questions PM me or check out JJ Virgin.

    Question:

    Given calorie in vs. calorie out, would you see any difference between eating 400 calories below maintenance and not doing cardio, vs. eating at maintenance and then burning 400 calories through cardio?
    (obviously it would seem that the cardio option was better b/c it will work the heart, but aside from that---you can't see the heart through my t-shirt:mamoru:)

    If you just change your diet alone your BMI doesn't change at all.

    Do a bit of both but keep your caloric changes under 500 kcal.

    Yes, if he diets he can get his BMI. I'll get you on a one apple, one can of tuna a day and it's going to get down fast as fuck.

    Some people get pretty lean without much cardio, but to be very lean during a certain amount of time, most have to do cardio.

    It's inefficient. You want a high metabolism to burn fat at a higher rate while resting.

    Dieting without exercise breaks down fat but your body reabsorbs it around your organs. ie greater omentum and around the liver.

    blah, how about a simple rule... if you have no abs, dont worry about burning muscle;

    once you reach that abs point, then worry, still you wil alawys need cardio to put on muscle to. gotta love the binging after a heavy cardio session

    Some BBers diet a long time before even doing cardio. What matters the most is the calorie deficit... I mean, if your body needs energy, it's going to use the energy it has available from fat cells.
