Not a fan of any of them, especially starvation!!
I'm a fan of clean eating and food combining...Going more on the veggie side of things lately...I've totally cut out red meat, pork, shellfish, dairy, sugars (artificial and any processed) and white foods (white tators, white flour, white rice, etc...) in favor of foods that are in their "natural" state...The only thing that I can think of using in an "unnatural" state lately are my vitamins (no gelatin, artificial colors, starches, fillers, etc...) and my protein shake (which is sweetened with stevia and made from pea proteins, again no fillers, colors, etc...)...It's worked for me!
I don't know what BFFM really is, but doesn't WW have many prepackaged foods which would be high in sodium (at least pp foods typically are)???
