I believe you -- most of what I know about keto I found on reddit so I treat it with a grain of salt. But I also know how it made me feel, and I can't do the di

  Ketosis takes at minimum two weeks to adapt to. For some, up to two months. It specifically takes this long because your brain has to switch to using the BOHB for its main fuel source (up to 66% of energy, perhaps higher). The remaining 33% is still glucose (other bodily functions still need glucose to perform, such as the creation of tears), and can usually be supplied by gluconeogenesis from the liver. I understand the urge is great to talk about science exploration, but if your only source is reddit, you can easily accidentally propagate misinformation. Likely someone walked away from your post thinking that the brain will fail on ketosis because it doesn't have glucose (which is actually a common myth heard from physicians). They will never read this reply. I would highly encourage you to read a complete book before even attempting ketosis, otherwise you won't have the motivation and understanding of the changes in your body to make it worth your time. If you want something light, read Keto Clarity. If you want a dense but approachable medical perspective, read The Art And Science of Low Carbohydrate Living. I've been in nutritional ketosis approaching a year, and I wouldn't recommend it to anyone who hasn't done their research on it.
