Doesn't ketones... work roughly the same as glycogen? I'm doing keto + IF (modified, I have a noon'ish protein drink, and then a meat heavy dinner). Just wonder

Doesn't ketones... work roughly the same as glycogen? I'm doing keto + IF (modified, I have a noon'ish protein drink, and then a meat heavy dinner). Just wondering if you've heard that, I'm new to working out (started at 515 down to 485 in 5 weeks, lots of muscle gains too though so fat loss is probably a lot better than if I'd just dieted alone.) Edit: I mean, I read an article once that said ketones could enhance performance in weight lifting.. my exercise is Cross Fit training at a Crossfit gym.
