Running while strictly carnivore

What do you fuel long runs with? How does it effect you getting better at your pace?

Do you understand that when on Carnivore you are using Fat(s) for energy?
Eat the proper amounts of fat(s) to fuel yourself. You shouldn't have to do anything special before a 'run'.

Yes I do understand that. I have lost 75 lb on the carnivore diet. Have been on it now for 7 months. I was talking like when some people before a race will carb load. So I was wondering what people on the carnivore diet do before a race instead of carb load. And have also read that carnivore is sometimes good for longer runs but not on fast runs like 5Ks and such. I was wondering what runners out there opinion were. Thank you

I wish I could help, but every time I've tried Carnivore I eventually stopped because my cardio suffered so much.
I feel as though if you are 7 months into it, you should be pretty fat adapted, so you should just continue doing what you are doing, no?

Have worse cardio times.
Which is fine, most people aren't competing when they run. For those who actually do races to try to win, carnivore is silly. Even if your body has switched to burning fat, fat will not fuel you like carbs.
For most people on this board it's fine. Not many folks here competing in races at a high level that are also eating carnivore.

Have fun? Idk what to tell you really.
This is maybe the most clear cut thing in fitness.
Carbs fuel runners. Plain and simple, it's objective. Sorry you aren't really a fitness type guy. More an ideologue

Why not just fuel your running with carbs and maintain carnivore outside of that window? Additionally carb loading is a traditional practice prior to big race days like marathons not something is necessary unless you plan to backup multiple days of long more intense runs.
If you are just running to run and do not have a training goal or goal time, I would maintain your pace below your LT1 which is more or less your conversational pace. Above LT1 your body will start using carbs as the preferred substrate for energy production and the faster you go the larger the split between fat and carbs used gets eventually hitting 100% carb and 0% fat once you get to threshold

I would like to do that, but anytime before that I tried it usually takes my body 2 weeks after that to go back into full ketosis. I am currently trying to get my time running better. I've kind of put my own self in this situation. I lost all the weight on carnivore and it really works on keeping the weight off easily for me. But also at 56 once the weight left, I decided to get back into running again. I love to run competitively. But it seems to be much harder on carnivore to get my time down. I was hoping someone had some sort of answer or way to do it while on carnivore. I know probably not, but I was hoping. Thanks for all y'all's answers.

It’s definitely possible, I’m assuming there are some good training resources online on how to get that done. But any prolonged high intensity endurance exercise is going to require supplemental carbohydrates to maintain performance

Kalei (@kalei_fit): A Harvard medical student and ultramarathon runner who shares her experience running high mileage (100+ miles/week) on a strict carnivore diet, focusing on steak, eggs, and butter for energy and recovery.
Other Athletes: Several runners in the endurance community have reported that a strict carnivore diet led to improved mental clarity, reduced inflammation, and better fat adaptation, resulting in higher weekly mileage without injuries, as noted in anecdotal reports.

If you are truly curious, look into how Zach Bitter trains and adjusts his diet.
He isn't strict carnivore, as he is keto, but he will add carbs on intense days or sessions.
He is an elite ultrarunner.

We've got a lot of posters on here stuck in the 90's when it comes to training, nutrition, and performance. They believe all the bullshite they were taught in middle and high school regarding diet and exercise.

Salmon ,ronricks-- Ty for y'all's serious replies much appreciated. I have had two slightly serious medical issues since I went carnivore. The last being a severe frozen shoulder. After six weeks of treatment, the doctor said he was amazed at the recovery that has been made so far. I attribute a lot of this to the carnivore diet. There is still much about this diet that needs to be studied and researched.

If it is working for you and improving other areas of your overall health, stick with it.
I could never stay with it very long. I'm going to fuel my evening run with toasted sourdough, whipped cottage cheese and honey

Y’all badly need better reading comprehension skills.
I didn’t say you cant do cardio. I said your times will suffer. Of course there will be carnivore diet folks who out perform people who fuel with carbs.
But those same folks would see improvement if they switched to fueling with carbs.
It’s not up for debate. I’m telling you.

No you’re just genuinely not smart. People have already mentioned that on here.

Only the Money board on here is surpassed in stupidity than this forum. We have people on here advocating for 1980's and 1990's diet and training theories all the time that we know are outdated or just outright old wives' tale type bullshite. We have people on here that still don't understand basic things like someone needs either carbs or fats but not both. People that come on here asking if they should do high reps with light weight or low reps with heavy weights. I get a headache reading the absolute stupidity posted on here at times its so bad. I'm not going to sit here and argue with so much outright stupidity.
