Great advice about running based on your personal relationship with carbs. I ran a half marathon PB of 1:46 during training at the end of an 16 hour fast and felt great. I’m 52 and a relatively new runner, but I know I can run totally fasted as long as I don’t drink coffee. I’m not sure if the caffeine blocks the body’s ability to access fat as energy, but something goes wrong.

This was quality. Thanks man

Oh, it is a definitely complex issue that’s filled with nuance. Great video. Great FOOD for thought.

Thanks!

Great topic and I have never thought of fasting for training, which I can try to see how my body reacts to different carb levels

Gosh Brodie for us RSSs who devour your podcast episodes, we desperately needed this!! Thank you so much!! I kinda avoid carbs during training and relatively lightly carb load before marathons and ultras compared to most. PLUS I’ve never yet used any gels nor sports performance nor recovery drinks either, You can imagine I think what ALL other runners tell me!! I do consume lots of bananas before and during marathons and sometimes I make my own energy balls with blended up dates, almonds, honey and Himalayan pink salt! My next marathon is only 3 weeks away too!! THANKS so much for this!!

Hi Brodie , interesting video 👍 . I am a keen cyclist and I have always been carb driven . I have never really lost any weight whilst doing my cycling training with carbs . So I decided to fast and start a low carb diet . I lost 10 kgs in 9 months and felt a lot fitter . I would do fasted zwift workouts about twice a week and felt great after them . Unfortunately over Christmas and January the carb amounts went back up and 3 kgs back on . I am back to fasting now and watching this video has made loads of sense ( too me ) . I have always thought the more carbs I eat/drink puts the weight on me . I definitely feel I am a middle to the right of your ‘ carb bar ‘ . I have had years of arthritis/cartilage problems with my knees ( gave up running due to this ) but I have just got back into running. I am starting the couch to 5k program as I feel my knees aren’t getting worse but also not better . I have had 2 osteotomies plus various cartilage ops over the years , aged 59 and I want to be moving as much as possible. Any tips on preventing pain in the knees would be great .👍

Thanks Brodie! Excellent content as always!

It also depends if your body is efficient at processing carbs. I actually run on butter and heavy cream in the morning and leave my protein and carbs at night.

Thank you

In addition to continuing discussions with Meaghann Featherstun, you may want to reach out to Matt Fitzgerald, if you have not already done so. His book, "The New Rules of Marathon and Half-Marathon Nutrition," provides fact-based nutrition information for training, racing, and recovery and has become my "go-to" reference on this subject.

Let’s goooooooo! Finally new upload 🎉

For me, I guess what is mattered and I probably follow the OFM mostly Zack bitter kind of format and during the week I’m more or less carnivore and that is really helped my mental health I mean day and night and I long run or races. I’ll use carbs but I find out I’m using them at about Half or less than I used to and it’s my digestion issues I used to have her all gone for for me. This is that really help me. It’s a lot of healing before I always think that all these gels and drinks can’t be good for me and they were not for other people I know they’re fine, I tried to be a vegan ones and they all that plants gave me a lot of gut issues so even though we’re all the same humans I guess we’re all a little different but for me this is really really worked and if you have mental health issues like I had and if you had a lot of digestion issuessome thanks I would say give it a shot give a keto kind of thing a shot and it really helped my life So in the end Monday through Friday, say this is my average day. I have my last meal probably 7 o’clock the night before I go to work about lunchtime I go for a run easy run hard run fast run whatever I go for about an hour run and then I come back and I eat again so I’m usually eating two meals a day And that satisfies me but it actually helped me to burn in my fat and it’s really working so that’s my daily routine like I said on weekends I probably start a long run fast and then I’m adding stuff to it about halfway through and if I feel little bit more rundown if I’m going 3+ hoursI’ll have some carbs so kind of something on the way back home that

Great video, new subscriber here!

Quick question please Brodie, my next marathon is 9 days away! The head coach at my running club insists that I need to carb load for a minimum of 2 weeks else it's a total waste of time ... any thoughts on that please?? Btw I'm vegetarian (I eat eggs and dairy), I do try to train to burn fat and I never use gels nor energy drinks either !

Your scale of carbs, some carbs, no carbs is absurd for a number of reasons. 1) there’s only two logical distinctions, carbs or no carbs. “Carbs” and “some carbs” are the same, just difference in degree. 2) you could do a scale with ANYTHING like this. Cocaine, some cocaine, no cocaine. Start off with no cocaine and see how you run and then add more until you get your optimal amount. Or, start with lots of cocaine and run and see how you do and then go lower as you see fit. Duh. C’mon man. Wait a waste of time.
