These mysterious changes.... I wish I knew what was going on
I think the difference between the morningstar products might be in the ingredients? Perhaps the sausage patties are made with more non-core items?
I'm a big believer in taking a program and tweaking it to suit your individual needs. If you have a hard time with not over-eating pasta, then why not take pasta out of the Core list and make yourself count points for it when you have it? I mean, as it stands the reasoning behind the food list is a little foggy already (is it because of nutritional value? carb count? people's perceived abilities to control themselves around a certain food?)... there is no reason why you can't modify it to make it your own. (That way, too, the changes won't be such a big deal - if you already have something that works for YOU, and WW suddenly tells you to stop doing it, would you stop doing it?)
All that being said, welcome to 3FC. It's ok to question WW here. We're all here to learn from one another and if that means questioning a diet plan, so be it
