What the hell is a Sister in Fat? It's a bond uniting women everywhere. The inner fatty living deep within all of us. She convinces us supersizing is acceptable as long as we wash it down with a Diet Coke. Here at SIF we celebrate "New Me Monday" EVERY Monday, eat lunch at high noon and hide food from those who judge us. It's not about size sisters. If you have an inappropriate relationship with food and obsess over weight loss/gain...you ARE a SIF! Welcome Home!
