I'm on the 5 and 1 Plan, and I was definitely having trouble with the "yucky" taste of the Medifast shakes. So, about a half hour before I'm due for a shake, I mix it and put into a small shallow bowl and place it in my freezer (at home or at work). In about 30-45 minutes, it makes a nice, thick, and much better tasting treat -- sort of an ice-creamy pudding. I enjoy them. Also, I found that the soups and chili were not filling enough for supper, so I started mixing in a cooked, crumbled Boca Burger -- they are very low fat soy burgers that come in a variety of flavors. The result is more of a stew and is usually filling enough that I don't even want the Medifast bar in the evening -- which I didn't enjoy that much anyway. So far, these adjustments have me losing 2-4 lbs a week, and not feeling hungry or deprived.
