It is somewhat individual too. I stay in ketosis up to about 35-40 carbs but it only works if my carbs are coming mostly from fresh veggies. I can't get away with the processed stuff or too much dairy. I lose and feel best at between 25 and 35 net carbs per day and my macros are not the typical keto or Atkins either. about 50-55% fat, 25-30% protein and 10 - 15% unprocessed veggie carbs (for the most part)
