Strict 7 (+ no nightshades + no nuts). >1 year.

I have to be super 100% strict Paleo because of my health problems (post-infectious IBS, SIBO, PCOS, prone to weight gain, insulin resistance, etc). I can't even have butter, dark chocolate, nuts and nightshades. Eating too much of even non-nightshades low-FODMAP vegetables, eating chocolate or even butter = abdominal pain, brain fog, severe bloating, etc. I have been eating strict Paleo for over a year now, but have only had to eliminate nightshades, chocolate and butter recently due to reappearance of some of my symptoms.

I hope that as time goes by, my gut heals and seals itself, because I would not see any problems in including butter, a bit of cheese, chocolate, some nuts and occasional coconut flour-based treats once in a while!

I believe that not everybody has to be that strict, it really depends on your health and goals!
