Here Mercola is ranked in the same "pure garbage"category as the Food Babe. http://www.nature.com/news/science-journalism-can-be-evidenc...
I don't think it's expensive and not so much of a difference in life style. I went on LCHF diet (low carb, high fat). I don't even miss sugar, or pasta or bread, I don't need it. Once I had a cheat day every 10 days, but now I don't need this stuff. I enjoy amazing 0 carb deserts, that are sweet too. Plus I am lucky to have a gf who makes amazing 0 carb cakes. For breakfast I often eat egg omelette with spinach (in leaves), with sour cream and butter. It keeps me full for a long time. My energy levels are through the roof. On LCHF you can also eat out, just don't eat starchy foods, stick to fat and proteins. I think this is the easiest diet to try and tweak later.
Watch out! Looks like a scam artist that sells voodoo.
