I've always thought that one of the best things about the Weight Watchers plan is their fast food calorie guides. Unfortunately, having two teens at home, we do a lot of eating on the go. And even though I try to look for healthy meal choices when we eat out, sometimes it's just good old Wendy's or McDonald's.But there's a site online that will tell you everything you want to know about that McDonald's Quarter Pounder with Cheese, including that it's 540 calories and 29 grams of fat - 29 grams! And while I still might eat that Quarter Pounder, at least I'll be eating it without blinders on. Go now and check out Chowbaby.com to find out how many calories are in your favorite fast food meal.
