Hey, there are several factors that have an effect on how fast someone will get into ketosis: total daily carbohydrate intake, intermittent fasting, amount of exercise, and supplementation.
It usually takes at least 4 days to get into ketosis, so I am not sure that there is a safe way to do it in 24h.
If your daily carb intake was very low maybe you can avoid carbs for the whole day, fast, and do lots of cardio.
What is your usual daily carb intake?
