My problem with Keto was that it made me dumb. I found that when I was in ketosis, my brain just wasn't as sharp. Tasks that should have taken 5 minutes took half an hour. My memory recall was not as good (not that it was great to begin with). I know it was Keto causing it, because my brain would go right back to normal in under half an hour if I drank a can of soda.
Agree with everything else though. It definitely changes the way your body works (the whole "sweating acetone" thing took some getting used to), and it's a killer way to lose weight.
Yeah; it never went away for me. I gave it a couple of months and decided that I needed my brainpower for work. I still try to eat low-carb, but not necessarily keto extreme.
See, this often happens due to mistakes (unless electrolytes):
Dehydration - due to low water volume it is very easy to get dehydrated even with normal electrolytes.
Too little carbohydrates. Even ketogenic diets need some carbs. Less than 30g/day or so, but still. The bottom limit has not been established but is probably dependent on too many variables. It is pretty easy to mess this up as the margin is thin.
Too much sodium to potassium. Mostly a problem if you're fuelling keto with processed foods. Processed meat tends to be loaded with sodium. To fix, eat potassium rich greens or plain old potassium tablets (preferably citrate).
How long did you try it? It can take a solid month to fully adapt -- you'll feel not great in the short term, but likely great in longer term. I've found my brain is much sharper burning ketones. I even stopped taking Adderall.
