Query: Health Diet

I read the whole Fat Flush Diet books including the cookbooks. They have alot of very interesting imformation in them. I consider myself pretty healthwise and read up on new exercises, vitamins and diets plans. This one seems very healthy, but you really have to take it seriously, Plans must be made to change your bad eating habits. You have to start thinking health from the start. No more of those run in and get a quick bite at the drive thru's. I thought the "no coffee" would do me in, but surprisingly it wasn't that bad. I did try the all natural coffee they talk about. It wasn't bad, but a little expensive and again hard to keep in stock in my kitchen. I lost weight and felt very good, but I live alone and have no others to worry about when it comes to dinner time.
