The thing about judging things like cravings, carb flu, digestive issues, etc. that are posted about on the forum is that you can't possibly know how many people didn't post because everything went smoothly. Companies know that when people are displeased with a product, they'll shout it to anyone who'll listen, but when pleased with a product, they really usually just respond when asked.
So, you'll rarely see threads like:
I don't have cravings!
I never got carb flu!
I didn't s*** my pants!
because those people are perfectly happy with the way it's all going, and don't need to post. I've made this point before in other threads, but I'll be happy to point it out whenever someone thinks that the complaints, issues, whatever people post about represent the entire group of people who have chosen to eat and live this way.
These forums don't necessarily represent the Primal community. They might more represent people who embrace the Primal philos0phy and who like online forums.
