I missed this thread before.
I'd certainly not advise skipping PV days. Vegetables and salads form an integral part of a person's "normal", and removing them every other day from our daily food intake is bad enough. Any "water weight" taken in on a PV day, he goes on to explain, is quickly removed the next PP day, so that's not an issue.
With any weight loss campaign, at target weight when it's all over, we need to have learned some good habits which have become a matter of course to us.
I admit to not having been a fan of veg/salad in my previous life (aka fat life). I love them now though...
