If you cut out all excess sugars and carbs?
I've heard that it can take as long as three days.

When they used keto for epilepsy they would make them fast 24-48 hours before feeding them eggs. I do targeted keto and it takes me about 12 hours to get back in, although ketostix aren't very accurate.

It's not really an on/off thing. It's more like at the start, you're using 95% sugars for energy. Then it slowly drops until you're burning almost solely fat. You never really hit 100% but 18 hours will get you close. This happens even if you have muscle glycogen left.

It's complicated dude. Just eat at a fucking deficit.
