I answered all the questions on the questionnaire. Both of the diets recommended to me, I know there is no way they will work for me long term (a long term change is essential for me). I do think the questionnaire is very thorough and it very well could steer some people in the right direction towards the best diet plan for them.

May be helpful for some, but it's basically just a lure to get you to buy a customized diet plan. It very well may be worth it for many people, but I don't like these gimmicks that give you a little information and then gradually try to sneak their way into your wallet, while collecting plenty of unnecessary personal information along the way.
