So I tried the special K diet a few weeks ago and it actually works. You eat their cereal two meals a day and have your third meal as the food you normally eat. You also have two snacks a day which can be one of their shakes or snack bars. I didnt use the special K shakes I just got a breakfeast drink mix. After two weeks on the diet I lost a little over 11 pounds. I think this diet would be good for last minute pounds you want to loose. Getting off the diet and back to normal food is a little hard to do.
