I have done my time with Slim Fast. I have been using the product off and on since I was in High School. Mind you, I am now 35 years old, so that tells you how long SF has been in the picture. The only thing I still like from them is the ready to drink Cappuccino Delight shake in a can. I put them in the freezer for a few minutes and have one for breakfast. I also like one of the snack bars because it reminds me of a Butterfinger, but the name escapes me at the moment. I can’t follow the actual Slim Fast plan. I always feel like I am starving. Even when they came out with the Optima formula. Not only that, everything is SO sweet I can’t even stand to eat the bars.
