First off, talk to your doctor. He or she may say that you can IF you eat some fruit or meat with the shakes. Second, SlimFast is one of the worst for you, as well as Atkins. I have found that Herbalife is the best for anyone, even those with diabetes. It is expensive (but aren't all diet shakes?), but worth it. And they taste great as you can have them with milk and fruits. Plus they are quite filling.
Please make an appointment with your doctor to weigh the options available to you.
