I’ve read that intermittent fasting causes the body to enter ketosis in as little as 12 hours with a regular carbohydrate diet (so a typical intermittent fast schedule is 16 hrs of not eating and 8 hrs of eating). This is supposedly because the liver depletes its glycogen in about 12 hrs. But don’t muscles also store glycogen?
Furthermore, I’ve read elsewhere that it takes the body 2-4 days to enter ketosis when you eat a lower carbohydrate diet.
Can someone explain the distinction between these figures and how long it takes ketosis to happen?

Yes. You have to eat less than 20g of carbs per day to get your body into ketosis in 2-4 days, then your fasting will work on your 16:8 schedule. If you want to stay in ketosis, keep your daily carb intake to only 20g. If you want to up it, exercise while you are fasting. Obviously, that’s a guideline and depends on age, activity level, and similar factors. Drink a lot of water, and you will feel when you are in ketosis with tiredness, constipation, and bad breath.
