Is it ever okay to fast after a workout?

Answered on August 19, 2014
Created March 13, 2012 at 1:01 PM

Hello all.

Just after opinions really.

I have some issues with night eating, so am trying to get my Leptin in check to see if that helps resolve anything. (No matter what I eat before I sleep, or what time my last meal is I wake up starving exactly 1 hour after I shut my eyes. Without fail.) I've had this problem for over a year.

I'm sticking to three meals per day as per the Leptin Reset and Mastering Leptin, with a BAB but as I've read its better if I don't eat within about 4 hours of sleeping.

If I workout for an hour until 8.30pm, would it be 'better' to eat afterwards, or is it okay to have my last meal around 6pm, train and then sleep afterwards, until the next BAB...?

For the record, I usually eat 7.30am / 2pm train at 7.30pm and then eat again at about 9.30pm. But I fear eating too close to bedtime might be what is affecting my sleep. I'm thinking I could try 7.30am/12.30pm/6pm instead, but I'm worried my recovery might be hampered if I miss my post workout meal.

Thoughts?

I was being prudent, as it would be incredibly stupid and arrogant to presume to know with any certainty without qualifiers, particular with so little information. I would have thought you of all people was aware that there is conflicting research.

lol I know what personal best is; I'm pointing out the fallacy of your claim I beat my 10mile TT PB by 2:04 minutes. If you were a trained runner and had consistent times for years it might be relevant but your personal best could be an hour and you beat that by 2 minutes which could just be because you dropped 140lbs. You haven't tried a run super-glycogen loaded like every athlete who wins does. I seriously doubt someone who likes mcdonalds cheeseburgers and is fat can eat mcdonalds cheeseburgers without the bun ad libitum and lose weight if they do its because they ate less calories.

Badly_dubbed- You lost the weight because you fasted or because you stopped eating 20 double cheeseburgers at McDonalds everyday?

I'm not sure it's as definite as all that. And even if it was, not getting good sleep can be detrimental in the long run too.

I regularly fast after working out and im yet to notice any ill effects. think of it as mr caveman, going out on a hunt and returning empty handed. ok so thats a bit extreme, but you get my drift.

you wont die and any catabolism will swiftly be repaired when you do resume normal eating.

my reasons?

Im simply too knackered to bother about eating after a heavy workout and really dont feel like eating most times, if i do then i do, if not, i dont :)

If you main goal is to lose weight, then don't eat. But, in the long run, it's a bad idea. Your recovery periode vill be prolonged, and you could even go into atrophy.

The best way is to eat something with good protein, meat, eggs or similar and take some quick carbs right after workouts.

It's fine, and definitely worth experimenting with to see if it improves your sleep. Of course there's many many factors to consider - how long until your next workout, what you're eating before and after, what workouts you actually do etc. If you eat well at 6pm, you'll still be digesting come 8:30 so your body isn't short on nutrients. Even if it were, it's designed to be able to cope with an intermittent supply. If you need to get up the next morning and carry a 100lb pack over your head on a 20 mile run then yes, you may not be fully recovered. If however you're eating sensibly for a couple of days before demanding your body be in peak condition then you should be ok - there's plenty of time for your body to recover the lost energy stores. Depending on the intensity of the workout you may not have finished rebuilding muscle, but that's another matter. Opinion is divided on whether it really makes a difference stressing about a post-workout window for protein. Not eating til morning may not be the absolute optimum for fast muscle growth, but no approach works well without sleep.

I believe Art de Vany is the guy you want to look to for the health benefits of waiting before eating after exercise. And as badly_dubbed says, the paleo point of view is that sometimes you don't catch anything. So it won't harm you, but it may not be optimal. And there's plenty of people in this day and age who manage just fine without eating to a script. Some don't even eat for days either side of a workout and still see no ill effect.

I don't like eating after a workout either. Then again, I work out in the evenings and don't like going to sleep on a full stomach. I'm sure I'd eat a huge breakfast if I worked out in the morning (probably why I don't). I would say worry less about the science behind it and worry mostly about what makes your body work best for you.

I would say eat an early dinner, digest it, then work out and do something relaxing immediately after before you go to sleep.

Working out makes your t3(active thyroid hormone) go to zero, not eating some carbs after a workout is very detrimental in the long run and will prevent weightloss and cause health problems.
