Thanks for contributing your first blog post, mom! I believe that the more we participate and stay engaged with how we're all doing in the competition, the better off we'll be in the end.
In regards to your question about Dad's lunches, I left you a comment with some suggestions. I think the secret to having Dad eat healthier lunches is to provide him with filling, yet healthy, food. I heard at Weight Watchers that the heavier the food (in terms of weight), the more full you'll feel. I think apples and grapes are good lunch foods. I'd also try to find a bread that is hearty and low in calories.
Let us know how eDiets goes for you. I'm really curious to see how it works!
