Here is a comment I made on a post at lowcarber forum about ketosis
Hi mfergi_200,
Well done for staying on induction for 4 weeks. I hope you’re pleased with your progress.
Generally speaking most people are fine if they stay under 50 gms of carbs per day but I would counsel you to add in those carbs slowly because it can be so tempting to treat ourselves just as once when we come out of induction and frankly the more gently you approach your CCL the better as that gives you plenty of time to gauge what’s going on in your body and the so approach does tend to lessen the chance of going over and moving out of ketosis.
Hope that helps,
Mark
