I was on an Atkins diet for six months, and this product helped me stay on my diet.  It's delicious and flavored with Splenda--which is a big plus for me since aspartame gives me migraines.  While on Atkins, I modified the mix by using half cream and half water instead of the recommended skimmed milk.  It fluffed up faster that way and had less carbs.  After I had gastric bypass surgery, I tried eating it using skim milk but found that the added whipped air in the mousse didn't sit well on my post-surgery stomach.  (Air/gas is not a gastric bypass patient's friend.)  It's been over three months now, so I'm willing to give it another try.  I would hate to give this stuff up because it's the best I've found (Jello brand sugar free cheesecake pudding tastes like wallpaper paste--a horrible consistency and flavor!)  Here's hoping that I can tolerate the whipped mousse again!
