Anyone tried Fasting Post-Workout?

by 115 · May 19, 2014 at 07:13 AM

From the general public (of bodybuiders) it is a sin not to eat a lot post-workout. Preferably you drink a super high-carb high-protein shake.

Usually after a work-out I don't long for that at all, and thus I don't think it would be very healthy to drink. I feel for healthy things like broccoli or such. Maybe it's just mental thing since I know it's healthy.

But has anyone tried intermittent fasting after a work-out? Maybe fasting until the next day or two days even.

The question is, why would you want to. In very broad strokes, the fed state is anabolic, the fasting state is catabolic (or at least, not as anabolic). You want to make the most of your workout by coinciding the maximum neurological and hormonal stimulus with the maximum anabolic (fed) state.

In addition, your suggestion doesn't make much sense in terms of natural or evolutionary logic. Most predatory animals seem to work best when they hunt (the workout) kill and eat (the meal!). How many lions do you see chewing a week-old carcass, then going to kill another deer, then wandering off again?! Certainly, some hunts are unsuccessful but it does kinda make sense to have your biggest meals not too long after you've taken some exercise.

i am pretty new to paleo, only 9 months now, but have been a healthy eater and athlete for most of my life. in the past month i have been experimenting with intermittent fasting so i was drawn to this question. i have been trying the daily window of eating mode, usually 1pm to 9pm, i think that i am enjoying eating like this, and contrary to what i would have thought, i feel extremely active in the fasted state in the morning.

my problem is that i work out in the morning, mostly heavy weight lifting, 3 days, then one day cardio. i workout between 8am and 930am. consequently my first meal is not until at least 3 hours after my workout. i have to say i feel fine lifting weights in the fasted state in the morning, just as strong as before, and i also feel good after. i do not normally have hunger or a necessary urge to eat after my workout. but reading the information here, and also the comment above from marks daily apple, i see that it is maybe not positive to fast always after working out.

so how can i continue to intermittent fast, without changing my workout time, and still be optimising post work out nutrition?

Denying yourself food after an intense workout, helps to have higher GH, but your body is also in a high stress mode. The most important goal in Fasting I guess is restoring glycogen levels. When glycogen level is depleted stress hormone adrenaline is released which is not good for sleep, where this may impact muscle building.

Hve done this whilst my main aim was fat loss and it worked a dream .. but if you want to gain weight I feel you need good quality carbs, fats and proteins within 2 hours for the best gains.

Yeah. It sucks. Why waste a perfect opportunity to replenish your body of protein and carbs with the least metabolic affect? no , you don't have to slam a protein drink and chow some fruit the minute you put down weights, but the vast majority of the most successful people (Olympians, physique athletes, bodybuilders, etc) prioritize recovery, and post-workout nutrition is a ginormous part of that.

People should definitely fast after hard physical activity once in a while for added health benefits. It's frustrating to see people answer something else without scientific knowledge about the issue. Here's one article but more scientifically backed articles can be found through a google search:

This is an Art De Vany thing. You work out fasted, then don't eat for a little while after the workout. Recovery is a bit brutal, but if you figure out exactly how much to eat and what the protein/carb breakdown is, you'll do ok.

The idea of working out fasted and not immediately having a post workout meal is to reset insulin resistance, and it seems to work very well for that.

I usually try to delay about an hour or so after the workout, although, I sometimes do work out non-fasted, and I do eat immediately after workouts. Not being consistent with this is a good thing as it follows the fractality ideas De Vany puts forth.

I generally find that I don't have a lot of time to work out, except for weekends, so I tend to do a full body workout on Saturdays for about two hours, so yeah, both upper and lower, and on Sunday I'm in a bit of pain from it, so it seems I have much better recovery by following Kiefer's carb backloading (and obviously include lots of meat after, and at the next meals), and also adding some L-glutamine as he suggested here on paleohacks.

sometimes im not hungry after a workout, so i don't eat until im hungry, keep it simple ;)

Unless you have a ton of fat to lose, and are considering it only after some sort of anabolic training, it doesn't make much sense.

Some people don't have an appetite for an hour or two after a workout, that's natural. Anything longer than that is actually going to interrupt your recovery, IMO.

I really think it comes down to your situation and the type of exercise. It definitely does not have a broad application in any sense.

Depends on your workouts, and what your goals are.

To build muscle, the general public replaces energy spent with some form of carbs and protein. Protein also helps in rebuilding the muscles.

If you're going for weight loss, I don't see why you can't have fruits and vegetables.

If you're hungry, eat something. If you're achieving what you want, then keep doing what you're doing. If you're not getting where you want, try changing it up!
