Dunno, I've been dieting purely by cutting calories. Sure I've leaned towards healthier options, but when on the road I've grabbed mcdonalds or wendy's chicken nuggets as a meal. Nutritional? No, but low in cals. And I'm down 50lbs since November 17th.
Would I do it every night? Not a chance. But by a purely calorie counting stance, you can lose weight and eat chicken nuggets. Wendys are a lot better, though.
