*Hi there! In the coming days and weeks I’m hosting several live webinar trainings about how to run a Personal Best race time, with special optimization strategies. Spots are limited, register for free here: **bit.ly/Running-Training-Flo*
I wonder if any serious athlete has tried the carnivore diet or else high-protein ketovore. I notice that some people state they lose energy on a keto diet over long physical activity. Yet some research shows that thosee on a keto diet can use as much glucose as someone on a high-carb diet. It's simply that the fat-adapted person produces their own glucose as needed from protein and lactic acid. But one problem is early keto diets restricted protein intake out of concern of the individual being knocked out of ketosis from producing too much glucose from protein. For an athlete, that is not an issue. So, it might make more sense for an athlete to eat high levels of protein, rather than following a strict medical keto diet that is designed for those who are metabolically unhealthy. If there is plenty of protein, would athletes still have trouble with glucose stores? Has anyone experimented with protein levels to see if it affects energy, intensity, and stamina?
Awesome episode with the world record holder. Thanks Floris for your work again. You are so consistent in putting out valuable interviews with some of the world best, how consistent someone should be in training to become such a phenomenal athlete like Zach! I think the takeaway of this short teaser is not to demonize carbs, rather use them as a tool when needed in a smart way. Thanks again and looking forward to the whole show next week! :-)
This is a very important topic you are covering with a world champion ultra runner who articulates his approach very gracefully = excellent content. I look forward to the full interview coming out in a week. Thanks for sharing this.
Good call to bring Zach to the interview! I am on lchf n I am not looking myself, I allow few carbs at times n I feel okay. As he said getting that metabolically flexible n fat adaptation is important!
Zach seems to have taken a pragmatic approach that makes for a compelling argument for me as I consider adopting this as a 43 year old ultra runner (looking to reduce inflammation as I age). Thank you for the info!
I think it’s important for people to understand that you have to be able to run in Zone 1 and 2 in order to even take advantage of Fat Burning for fuel. So, if you’re HR is routinely above those Zones then you’re not going to be able to take advantage of Fat.
So you burn sugar if you run fast, but if you empty your glycogen reserves, you'll be burning fat if you're fat-adapted. That's the key, and why you need to get your body fat-adapted also. That's my take on this.
@@TheVRTester - You state the obvious and your comment gets dismissed. This is beyond debate at this point. Many studies have shown people in ketosis while on the keto diet, whether or not they are exercising at all, much less Z1 or Z2. Someone commands you to provide scientific evidence. There is a century of hundreds of keto studies. Anyone can take their pick and see what fat-burning means. A keto diet reduces carbs and protein to such an extent that there is nothing left to burn but fat. The mechanism of this has been understood a long time. This isn't exactly a secret at this point.
Thanks for that Zach. Am on Carnivore diet. Training for marathon. In run fasted except for a coffee shot in am. What race carbs are ideal for boost at say 17 to 20 miles into race? I've been researching this and most people I know are still on high carb running diets. Which fuel is best for marathon and about when?? Than you so much Zach. Thanks for sharing ☺️.
Gr8 implied question. I’d be worried about crapping my pants in public. Within minutes of swallowing some carbs/sugars, I’d be losing a lot of bodily fluids…! 😮
I've never felt bad on a workout and being on the keto diet. I've taken a break from keto for 2 years or so and now back on it so I'm interested in taking in some carbs before workouts and see what happens.
Great discussion! I would've liked to know if he's doing typically intervals that are over 1000m because the shorter intervals would make little sense with the distance he's doing.
I think this might be nutrition for ULTRA-Marathoners ONLY. NOT regular distance runners like 10k 5K. Because you have to maximize fat usage efficiency (fat-adaption) for very long races, since you can't store as many carbs near your muscles and in your liver. Carbs in my research are the most complex. But this guy is training very cutting edge on his fat adaption I believe, so he wants to keep carbs at a minimum and just a little extra for interval or faster workouts and peek days. This is interesting because my running books talk about carb adaption but not very much about fat adaption in this way. But carbs might still be the most complicated, and he might be doing something thats simple but has high potency for ultra-running and very effective.
I do agree that this approach is more applicable and beneficial for longer endurance events, that can be performed at relative low intensity, with high percentage of energy coming from stored body fat vs glycogen

Sorry to say: he talks a lot but says little. He is very bad in delivering a message. He should think more before talking. That might better structure his talk.
@@justus005heres a fine line between leaving it too late...if the heartrate is using say 60% carbs 40% fat @ ones race pace marathon then waiting til 30km is too late. Thats why its suggested to run the 1st hr without gels to really target fat metabolism without Any Insulin spiking. Once the body is in the thick of fatty acid breakdown @say 3-3.5hr marathon pace.. then utilising an 87cal isotonic gel each 25min is smart...thats a sensible 200cal/hr rate which won't totally switch off fat oxidation & massively spike insulin. Cheers

Yeah, very interesting as I'm a fat adapted/fueled runner too. Can't wait to get the full episode.

As an endurance athlete, this is supremely helpful content. Thank you!
Such a smart way of talking about the views and interpretations of the body and goals of the day!! Very nice interview.
Glad to hear that Damien. Thanks!

If your Keto/Fat adapted you use fat all the time, not only in Z1 or Z2.👍🏻
@@TheVRTester Provide scientific evidence for such a bogus claim.

Look up Dr Tim Knoakes take on this topic of not needing carbs as a source for fuel in elite endurance athletes

Bananas. This is what Dean Kanazes eat on his ultra runs he says he does not use any gels
Another one to look forward to 🙂 your getting some great guests 👍🏻
I’m kind of new at using carbs as a tool...super excited to have found you!!
So glad!
I wondered what it would be like to live and train on keto and on race day incorporate carbs during racing.

What about carbo loading?
Did you even listen?
@@TheVRTester Yes, but he is using carbs during the race so wondering if any short term carbo loading say from the night before
@@RowOfMushyTiT Fat load for long term fuel. Hit the carb dose only at end range needs for glycogen stores.

Using performance as a compass, I'd prefer to listen to Kipchoge, who eats a lot of carbs.
Does he run ultras? Ok then.
Very frustrating no fun, eat this, eat not this, eat that
frustrating? What? Being an id10t?
