Jello brand gelatin is sweetened with aspartame. In the book, the gelatin dessert mentioned in the Sample Induction Menu is a gelatin dessert sweetened with sucralose. So they aren't the same thing.
I agree with Georgianna that desserts shouldn't be an everyday thing, but a once in awhile thing. So instead of planning for something sweet for dessert, why not plan for a really, rich creamy cheese like Brie or Camembert or "say no" to dessert altogether?
Use your Atkins journey to break the bad (or questionably bad) food habits you have adopted and make new habits.
