No, I haven't heard of Accel. Do you think you need help with appetite control? This is the only diet I have ever been on where I don't feel hungry all the time or think constantly about what I am going to eat for the next meal. I am surprise that Atkins felt the need for such a product, since the diet is so filling. Looking forward to see what others have to say who take it. I know everybody is different.
