Listening to radio talker Mike Gallagher mentioning WW points when he has lost over 50 pounds, and a friend losing 35 pounds on WW, I signed up for WW (formerly weight Watchers) and do it all online via the app. One of the three plans is the Purple plan - 300 foods you can eat freely, including potatoes! On Purple I can have anything I want as there’s a daily and weekly number of points for “extras”. Google WW Purple plan.
You can use that big list of food any way - vegan, vegetarian, keto and low carb. There are online boards for all types. It isn’t fast but it’s without pain. I lost my desire for sweets on day one which was a help, and I indulge in potatoes a LOT!
Thanks much for the info.
