Lifting In A Fasted State?

SkeletorSkeletor The Conqueror Worm ✭✭✭

Just curious-- how many of you here lift in a fasted state? Does your performance suffer when you do so?


Lately I've been lifting towards the end of my day, after having eaten most of my food. Today, though, I decided to switch things up and lift while fasted. It'd been about 19 hours since my last meal. Well, my performance sucked in a major way and I felt weak as hell. I left with a bad headache and a feeling like I was going to vomit. Couldn't even do my cardio afterward because I feared I'd pass out.


Anyone else ever have this happen?

    Yep. That can happen, especially if you are not use to working out fasted.

    Caffeine pre workout can sometimes help a bit, I find. But other times sugar/glucose(dextrose) is required.

    I should add, that you are not going to be breaking any records in a fasted state vs fed state, imo.

    But working out fasted is supposed to have its benefits (apparently)

    Sort of. I felt really gross and nauseous after the gym and had to lay down for a few minutes when I got home. Maybe my blood sugar dropped because of the fasted training, not sure. Anyhow, after a hot shower I felt better and sat down to a pretty big meal. Now I feel pretty normal, except I'm sore from having performed so poorly. I think I messed up my breathing and used crap form on a few reps, because I feel like I strained some stuff.


    I guess I'll stick to what I've been doing and eat before I work out from here on out lol.

    I used to feel good when I did this because I had to work so hard. But my performance was stuck for a long time. Basically I busted my firm butt and sweat without getting stronger or leaner. Made me believe that I've reached the point when you just don't make fast progress anymore. But now I'm improving my performance rapidly.

    It doesn't get easier... It's you who gets better.

    Success has a price, not a secret.

  • I lift fasted every time now. last food around 8pm (some nuts, not a meal) and one Bulletproof Coffee at 5am with BCAAs at 6am and lift from 6:30-8am. No issues at all performance wise, but not tried 19hrs or a full day as I always train early in the morning pre-work. 


    Been working great for me for a couple of years. Have played around with protein shakes before and different foods, but made little difference. All my lifts are heavy with highest reps of 8, but average 5 reps. Deads, squats, Cleans, Bench, Dips and Pulls are my main lifts.

    SUCCESS: A lot of little things done well

  • I often work out in a fasted state and LOVE IT! 


    Usually I carb cycle every 3-10 days, depending on my workout schedule.  I can't explain it exactly but I just feel soooo much better when I'm at the gym in a fasted state.  I feel like my body really kicks into a sort of peak ketogenic state and the mental clarity improves. 


    If I had carbs the night before, I feel like a freaking BEAST as it's almost the best of both worlds w/ plenty of glycogen for intense actives while still getting that constant energy stream & mind boost.  Ex. I can lift heavy weights for hours & still have energy for a plenty of racquetball afterwards which is an intense sport in it's self. 


    I don't have any science to back it up but I think the trick might be that you need to get fully keto-adapted so your body is used to relying on fat for fuel.  The first couple of weeks in the gym are definitely not fun but then it slowly gets better and better.  Then once you re-introduce a little carbs every week or so, it's just amazing.  There's also a lot to be said about the possible benefits of waiting to eat afterwards (especially carbs) but that is another topic.

  • No carbs for me on workout is a disaster!


    I workout first thing in the morning with BCAA, HBCD and Gatorade (about 45 grams of carbs). I used to start sipping during the workout. Now I find if I drink half of it 30 minutes before I start lifting, even better! 


    Post Workout I do Rice Cereal after (about 60 grams of carbs) with some butter and a whey smoothie. I guess you don't need that butter right after a workout but I am starving in about an hour if I don't.


    note I appreciate that a pinch of salt and coconut water is better for you than Gatorade, it just costs so much more. It is a rare area of compromise 
  • my routine for a lot of years was to train capoeira or do yoga first thing in the morning, followed up with a bowl of cereal (then later on that evolved to smoothies with the occasional crazy pancake day). there was no physical training rationale for this, just that my day didn't feel right without a training session and first thing in the morning was the easiest time for me to consistently get it in then go about my day knowing that i've already gotten the most important thing (to me) in. later on i pushed my training back to noon-ish while doing bulletproof IFing.  i never really had a problem with it but looking back there were days where i would feel weaker and maybe a little jittery, especially in the early days of BP IFing.  i like to have a more or less empty stomach when i do yoga, slightly less so for capoeira, but for lifting i definitely like to have eaten something earlier in the day. so far, the times i've experimented with pre-workout carbs haven't seemed to do me much good, i seem to lose a little bit of energy/enthusiasm, like my brain feels like it already got it's reward so there's no need to get hyped up or something. my lifting days are usually eggs/veggies/bpc for breakfast, a snack with some protein, beef/veggies/bpc for lunch, wait a couple hours, lift in the late afternoon, PWO whey/carbs, then rice/potatoes/fish/bananas/fruit/etc. 


    hopefully that makes sense. i'm in between the PWO carbs and evening meal as i type this....

  • If you lift weights fasted your workouts will suffer. All things being equal you simply cannot move as much weight with as much volume in a specific window of time sans carbohydrates. Anyone who tells you otherwise is either full of shit or kidding themselves.
  • This is what I am noticing, my strength is declining when lifting on a Bulletproof fast. 


    I want to know what people think about post work out food. Dave says in the book to have high fat/ high protein/ high veg after workout. Then on that night have extra carbs. I have always been told to eat carbs straight after training? Is his reasons for saying high fat instead of high carb because when you follow BP diet you become fat adapted or  something else.


    I dont know whether to follow Daves advice or have carbs straight after

  • Dave has very limited knowledge about training and exercise and is a proponent of very little exercise so you do not want to be getting this information from him.  Fat has very little to no benefit when consumed post workout, and when the training is anaerobic it has very little overall benefit outside of the recommended daily amount for proper hormone function etc.  To date, there is extremely limited to no scientific data showing that fat adaption even exists when it comes to anaerobic exercise and the fuels and fuel systems that are used during said exercise. 


    Keep your post workout meals to protein and carbohydrates with fat kept to less than 10g, consume the majority of daily carbs close to training, keep the majority of daily fats to far a way from training, low carb diets are not beneficial to advancements is strength and muscle growth, adequate carb intake is necessary to gain the largest benefit possible.  This is is the summary of the scientific literature to date which is quite vast.


    So should I fellow like a carb-backloading style of eating (fats before training then after training have carbs all the way leading to sleep time) 

    I train and I want strength and muscle growth and have noticed that when doing it Fasted in order to get mTor as he says I am weak and sort of finish my sets early.

    I am currently doing 5x5 training protocol. 

  • Yes you can, though I usually recommend a pre workout meal that has carbs in it as well.  Protein spaced evenly throughout the day.


    Will I still be burning fat if I consume carbs before training?

  • Very in depth reply!  as always Cheers Jason!


    In terms of Using MCT oil to produce ketones in the morning and then after training eat carbs all the way till night time? Will this work too as I feel great when using MCT oil in the morning cognitive function wise.

  • Laying down the science, nice work Jason.

    Just asked the question regarding having a high carb meal post workout: 

   (START AT 19:00)


    Long answer short: Yes you can have a high carb meal just not high sugar.
