Someone correct me if I'm wrong, but SF jello is not allowed on induction. You are supposed to avoid aspartame--it causes stalls for some people. That being said, many people do have foods/drinks with aspartame and don't have any problems. If you find that aspartame slows your loss, there is a recipe in the kitchen section for jello you can make yourself using unsweetened kool-aid, gelatin, and splenda.
