Update: I've lost 7 pounds since Monday morning. That may seem like too much, too soon, but it's typical to lose 8-13 pounds during the first two weeks of South Beach. So I'm actually right on track. I've also been exercising all but two days this week, so I think that's helped.
This week has been a little frustrating in terms of meals. It's not like I've really been craving sweets or anything. But I'm a vegetarian (although I do eat fish), so every lunch and dinner this week has been salmon or tilapia with lima beans or great northern beans. Luckily, I found a recipe for chickpea soup that doesn't break the diet and makes 4 servings, so I'm going to make that and have it for dinner this week. I also found a recipe for salt and pepper shrimp that I might try. I have a list of rewards for losing a certain amount of weight, and the reward for losing 10 pounds is two new books. I think at least one of those books is going to be a fish or vegetarian cookbook.
I hope everyone else has been doing well with your respective diet and/or exercise programs!
