Years ago I had switched from their point system (similar to green) to their whole food plan (similar to purple). I lost plenty of weight but I was tired of counting so I switched. I gained 4 pounds in 1 week because of all the zero point options. I can not be trusted with zero point foods. If you are able to control your portions and the amount of food you eat then it shouldn’t be a problem. For me, I will always need green.
