The latest foodie trend is called “Semitarianism” (you better keep it in mind since you might hear a lot about it in the near future). It consists of alternating vegetarianism and omnivorism, i.e. days when you don’t eat meat at all and days when you do.
Food is the new cool thing -- just go to Williamsburg, Brooklyn on the weekend and look at the rooftops. All you can see on every other building is smoke rising from grills and people barbecuing and eating all day long. Looks like it's not about looking like a skeleton anymore, but it's more about eating healthier -- and riding bikes. Why? Maybe because even when money’s gone, food remains a daily need.
Paul McCartney already adopted the Semitarianism “diet” and created what he calls “Meatfree Mondays." So, why don’t you also give it a try?
