I think it needs to be kept in mind that the statue's of Florida require any one giving out Diet and or nutrition advice has to have a certain level of education and be licensed and partcipate in continuing education. I beleive a few polsters on this and other threads are coming dangerously close to praticing without a license. I also beleive if anyone chooses to follow their advice and is injured they may have grounds for an action. I'm suprised TOTV doesn't require a clear statement by each participate when they post that they are not an expert and not licensed. Here is the link to the requirements
