if people read the forum and google sends them here when they are researching a diet then they see other people posting about diets then you will see that pattern of diet threads cause then they will post another.
i agree its everyday but you can always post up some other threads on different diet topics. we have so many people on here who read the forums but don't post
we are seeing on the AAS subforum every other thread about "i'm not Ronnie Coleman after 3 weeks of steroids". a lot of these podcast people also will create a fad topic and then you will see threads follow onto here.
