So, I have this theory that may be somewhat cockamamie, but it's what I've been going by.
Sometimes, even when I know I'm going to be eating a big, non-point-friendly indulgent meal, I will decide to start off with a small salad and then still eat the full big meal. Why? Because sometimes that's what it takes to ensure that I'm eating fresh, leafy green veggies. With as often as I eat restaurant or deli food, that house salad is often the best way to get in some fiber-rific veggie goodness.
I do this knowing full well that it means I'm eating MORE food instead of less, and that it adds to my calorie and point intake, and that I'd be better off just eating the salad and not ordering the big meal. But, like I said, this is my theory and every once in a while - like this week, when I had a delicious but non-diet margherita pizza for lunch - I feel better knowing that I've started off with a plate full of nice mixed greens.
