Ketogenesis

[VTeton]

I dropped 80lbs on my diet of meat, seafood, whiskey and veggies. Shit works wonders if you can avoid sugar/bread.

I eat like a king but it ain't cheap. Took down a 32 oz prime ribeye on Friday night with a bluefin tuna avacado salad to start. A little whistle pig to go with it.

Haven't eaten a single piece of bread in months. No pasta for a long time. Barely any sweets etc.

Sounds like the third circle of Hell.

I'd be ok with everything but the pasta.
love me some pasta/
And yeah, eating healthy ain't cheap.

I know a guy who is keto all week long, but does a carbo load for the weekend including pasta, and lots of it. He's a pretty hard core weekend warrior.

But I also have learned that when doing medium and longer mt bike rides, I need to chug a gatorade shortly before the ride, to stock up on quick burning carbs for all of the high intensity "sprinting" that comes with biking in the mountains.

Not a critique, just a comment. You can bike in the mountains on little or no carbs. The weenie sprint is a disease that can be cured.

I have done it. This is all just my personal experience, but mountain biking effectively (for me) requires short bursts of speed (I have no idea what you mean by "weenie sprint"). I could ride just fine without carbs, but found that I was pretty much walking every little short steep section because I had no burst in my legs. And while walking my bike is a regular occurrence for me and I'm ok with that (I'm generally an out of shape hack), I was riding trails I know VERY well and was walking things that pre-keto I was riding. Once I incorporated the pre-ride gatorade, things changed dramatically. A couple of friends I rode with both pre and post gatorade also noticed the difference, they said I was much faster (not that the gatorade made me a rocket, but you lose a lot of time getting on and off the bike, so eliminating those dismounts made me a lot faster overall).

Danno pushes in jorts.

Jorts, gatorade, and an e-bike?

I did Keto for a couple of months just for kicks. Lost weight and ate alot of fat. I really got sick of the consistency of my food. I found that my endurance suffered but no real other gain or consequence. glucose is energy for muscles period.

i used to run ~10 miles per day around an 8min pace (along with daily lifting & swimming) on a near keto diet. when i started (not at 10 mi) i lost ~65lbs in about 4 months. i made it a few explicit weeks full keto/consuming nothing processed and would drop another 5-10. IME if you work up the muscular endurance it shouldn’t be an issue, but i would not be training or competing on that diet if i cared about my performance as primary goal.

This, I believe, is the bottom line correct answer.

I found I can only go 1/2 speed on a keto diet (if that). If I have anything "punchy" I need to have some carbs beforehand to fuel my way through the high output stuff.

[Dantheman]

glucose is energy for Type II muscle fibers period.

FIFY. Type I muscle fibers predominantly oxidize fats/fatty acids.

but i would not be training or competing on that diet if i cared about my performance as primary goal at sub-ultra distances.

FIFY.

Started keto a week ago. So far so good. I am supplementing with electrolytes and exogenous ketones.
Ben Greenfield does some crazy endurance comps in ketosis. He is a bit of an outlier for sure.

Wouldn't that bump you out of ketosis? Your body would crash even harder when those carbs are used up... and you're not back to burning fat yet since ... you're not in Ketosis.

I don't test my ketone levels regularly so I have no idea what's happening internally, but I can certainly say that what you describe is not what happens to me. One 20 oz gatorade will fuel me for a 3 hour ride. If what you described is correct, I would bonk hard long before the ride was over.

Dan made some great points last year in the other keto thread about training your metabolism to alternate between fat & carbs. With the conclusion (for me, anyhow) being that strict keto isn't needed so much as a healthy diet alongside exercise. A brief period of keto to jolt the metabolism back into burning fat at least part-time is all I needed to get my metabolism back to operating at a healthy clip.
