SauteePan - I know that financial shows and commercials promoting weight loss products always offer a full disclosure because these fields are prone to lawsuits.
With respect to financial advice there is always a disclosure if the commenter or television owns shares of the company that he is promoting and there is also a disclosure at the end of the show to remind people to seek their own financial advice and that the information offered was only an opinion of the panelist.
This also happens with weight loss products. They usually say that each weight loss claim is unique so that people purchasing the product or service understand that the weight loss is really dependent upon your individual effort.
This is important because people have all sorts of expectations and often want a quick fix to everything.
