One of the more extreme low carb diets, the Atkins Induction Phase, allowed up to 20 grams per day. Other diets such as keto or The Zone allow 50-100 grams.

If you constantly blow out of ketosis, you'll literally accomplish nothing with the diet.
Hence why keto-stix and other indicators are important- no one value works for everyone.
I had to eat less than 25g/day to maintain the keto diet.
Unless you also achieve a caloric deficit.
edit: opposite words day
But of course, "the same meal over and over" is counter to the purpose of your web site, which is to suggest new meals. Great job, and I wish you success!
Interesting. For how long?
I have seen people fast (i.e. no calories, but water and minerals etc) for two weeks, without too much messed up brains.
From what I've heard reported[1] about periods of extreme caloric restriction is that it takes the body around 4 days or so to start dealing with the lack of carbohydrates. Until that point the person feels tired, grumpy, headachy, out of sorts, hungry.

I found your site and it was really really awesome back then, I was impressed! I'm glad to see you're still working on it. I think you're hitting on something really valuable here.
Thank you for your work and good luck with it moving forward.
