I think for events >24 hours, it could could be a very useful strategy.
I’m not being aggressive, I’m merely pointing out that what you’re posting is classic “bro science”. Anecdotes that aren’t backed by the scientific literature.
The thread is about keto. Is 100g CHO/day keto?
Now you’re moving the goalposts. Periodised low carb is not keto.
Keto is a sub optimal for endurance athletes, it won’t make you faster and it doesn’t have any weight loss benefits compared to any other diet if calories are equal. I’m happy to be corrected if you can provide some solid scientific evidence.

Lets not forget the original post in this thread
This whole keto fad destroys people’s performance. This Forum is about giving people solid information to make them faster and most of all, make them better athletes.

So after approx 4 weeks of Keto I have the following results:
Total Bodyweight: 91.6kg - 89.5kg
Body Fat: 24% - 21.1%
Muscle Mass: 66.2kg - 67.1kg
Visceral Fat: 12 - 10.5
FTP: 254W - 236W
Stats are from Tanita scales, FTP is from TrainerRoad.
From a health perspective I am very happy, especially with the reduction of visceral fat (3 notches on my belt). Good to see muscle mass go up too. FTP drop wasn’t surprising and now that I’m moving into a carb periodization approach I’m sure that will go back up. This is OK to do during an “off season” I think, especially if you need to get control of your diet eg. like after Xmas. Doing the Keto has really cleaned up a lot of my eating habits and I’m not craving processed carbs now. Just sticking to veges, sourdough and pasta.
Training is interesting atm. Even though I have brought back carbs the workouts haven’t suddenly got easy at this lower FTP. At the higher value I was stopping during intervals and finding it really difficult to complete workouts. Now I’m finishing a workout without stopping and feel like I’ve done a solid workout. The recent podcast had Chad talking about increasing stamina without increasing FTP. I feel like I’m doing something like this atm. Until this I was getting worried that I’m gettting good at Ramp Tests but no good at workouts! Initially I was thinking of doing another Ramp Test but I’m not rushing to do that now. I’ll finish the Speciality Phase I’m in and see how the event goes. After that I have a break and then start Sweet Spot Base to prep for next year. Plenty of time for Ramp Tests.
Hope this gave you all something to think about. Interesting experiment.

I tried both. Ramp test with carbs and ramp test after fasting. Both were almost the same. Recently I set a new PB on one of my local climbs. after fasting for 16 hours. One side effect was that after the PB I continued to ride moderate for another 90 minutes and had to stop for a pee multiple times. I ate a lot when I came back but felt lousy the whole day.
Not my experience: Same result
As my father is type2, this was exactly why he became diabetic.

To the original post, please keep an eye on your internal health. Keto may work for some and make you look pretty on the outside, but it did not work out for me. I look back and it could have wrecked my life and I fear it can do it to someone else. I quoted one of my posts from another thread to give a brief history of what happened to me.
Dunno about handholding… Pocketbook fleecing seems likely, though.

I hear what your saying, but I’m not debating one side or the other, I was stating my actual experience with it.
I think the short test is a better predictor of your FTP than the ramp test. I’ve heard that the ramp test can over estimate the number, but it is also good to use both or all 3 tests to verify the numbers you are getting.
Shayne from GC Coaching has commented on this in their podcast “Never Going Pro” - a ramp test is a great way to judge what your max aerobic power is or VO2 max things like that. But a true FTP test should be a lot longer like 20 to 30 minutes, ideally. And then if it’s a 20 minute tests, you should ideally do some kind of burn out effort, like I think Zwift uses the three or five minute 115% effort before because you’re trying to decrease your anaerobic contribution to the power produced. That’s why people have a ramp test and they have a super high FTP because it’s being over inflated.
Totally agree
And along the way people on one side of the discussion will call people on the other side stupid… 
Guys in the middle, like me, are called stupid by both sides
