Fasted cardio Vs Fed cardio

Just curious, a lot of fitness folk whether bodybuilders or fitness models promote fasted cardio, and the argument is it burns more fat because well, your stomach is empty and it focuses purely on your fat. Solid argument.

However, if doing cardio on a full stomach, and that cardio only eats into whatever is in your stomach, well does that not eventually average out at the same result anyway, because although you're not burning straight into current fat stores, you are burning straight into food which would be stored as fat, therefore kind of reserving less fat, and ending at the same result anyway?

There was a study I read not so long ago that showed fat loss was equal in fasted and non fasted cardio groups but the fasted cardio group lost a little more lean body mass.

As with all studies, holes can be picked but try both and see what's best for you.

Edit. There are also studies showing the opposite lol.

Thanks for that post man. Yeah, that's the thing I've come to realise over the years, there's science and evidence for every approach, just seems to be finding what works for you personally

Its what goes in vs what goes out in terms of energy spent in my opinion, I train fasted purely because I train 1st thing.

Read a study the other day claiming that fed cardio resulted in more fat loss (will try to find it) but most I've seen basically say there's no difference e.g.

just now after lifting ive been doing cardio in an attempt to lose fat. before the gym ive only been eating protein and no carbs - ive been following a relatively low carb/ higher fat diet for 2 months. Progress is slow but i am noticing a little more definition and my strength has pretty much stayed the same.
 
So this approach seems to work for me but may not for everyone. I guess as mentioned above, decide on a plan to follow and stick to it for at least a month and see how you get on and amend if needed

For me I do cardio when it is convenient, generally it comes down to energy in vs energy out. No magic.

I personally prefer fasted cardio just because I usually do cardio in the mornings and won't start eating until later on in the day and I noticed I was losing fat quicker that way however I did also lose some muscle, not much of a problem for me as I'm trying to get my body fat a little lower before I start building.

Regardless of what you have got in your stomach, when you exercise your body is going to be tapping into your muscles glycogen stores for fuel (as well as some fat, the ratio depends on the intensity of the exercise).
 
Not having eaten for 10 hours is going to make zero difference to your muscle glycogen levels (assuming you are not on a ketogenic diet and are eating carbs regularly of course).
 
If you are doing longer duration cardio (2 hours) then it will make some difference as you can completely deplete you glycogen stores in that time and you won't have ingested any more carbs to replenish them), but this won;t be most people.
 
In short, it will make no difference to the vast majority of people.
 
Cheers

This is what always gets me.... everyone who does cardio/exercise in the morning before eating assume they are training 'fasted'. At the weekend I do a 20min jog before breakfast, but before I went to bed 8hrs ago I had eaten, and I'd eaten a reasonable amount the meal before that too. I'm pretty sure that those 6-8hrs in bed haven't done a lot to put my body in a fasted state. 95% of people who claim that fasted cardio/training is working for them are not truly fasted, not even close IMO

id never really thought about it that way before
 
so what would true fasted cardio be ... 12+ hours after last meal? or longer?
 
I normally train at 5am due to work and the fact my gym is rammed from 5pm until 10pm and i always considered it fasted training however it was probably 8 hours after my previous meal in reality

Technically yes.

But for me, the results are not the same. Hormones come in to it too.

Depends on what you term "fatsed"
And yes. 10 hours will have an effect n the food you ingested. A lot. Chemical reactions are majorly factored by time. Part of the equation. The body does not stop as you are sleeping.

As BigMacca and dirtyvest described, I always train AM before eating but don't consider it 'fasted' as in glycogen fasted.  I'm happy to go up to about 90 minutes without eating before I need to replenish glycogen stores.  Any hunger that I experience is usually down to hydration rather than low energy.
 
If you're keto, then it's different as your glycogen levels will be minimal anyway, plus eating is obviously not going to replenish them as you'll be eating fat.

Re: Fasted cardio Vs Fed cardio 2017/06/23 10:19:25 (permalink)
cardio post workout for me , you will be depleted to a certain extent as you've just trained and your heart rate will already be at the ideal rate for burning fat , fasted cardio it normally take me 10-20 mins to get my heart rate up comfortably and i do seem to burn muscle very quickly and generally feel like dirt so its always something i find less effective and avoid .
 
But yeah energy in = energy out , but fasted cardio does seem to take some of the energy from muscle tissue in my experience. My results have always been a whole lot better with condition and muscle retention with post workout cardio with everything else being the same. Although ive seen others do really well with it.
