The past few days there was some questions about this topic on the Accu-Weight list-serve – is it a no-no, a 1/2 cup a day, a cup a week or only in emergencies to not do any major damage when cheating? Here is the best answer I found on this:

Straight from the mouth of Dr Schwartz:

Make a 4 serving packet of Sugar Free Jello, but pour into 3 dishes for 3 servings.

And have no more than one serving a day and one box a week.

Some background info: It appears that this is one of the very few things that Barbara & Dr. Schwartz have altered back & forth. You can pour the packet into as many dishes as you want, Dr. S was just suggesting 3 to make it bigger servings. That was the original rule, and only one box per week. Last year Barbara had said we could have more than that because it would be better to use an extra jello than to cheat on anything else. Your best bet: limit yourself to one jello box a week, but if an extra serving of jello is going to keep you from eating XXX or XXX, than that would be the best way to cheat.
