If I were you I would try and revamp your kids' diet as well. If eating a high carb diet is bad for you it is also bad for them. Kids need carbs because they are growing, but you can make sure that those carbs come from veggies, fruits, and some whole grains rather than a bunch of highly processed junk. I've taught my 11 yr old daughter the importance of reading food lables and paying attention to serving sizes. Yes, she has the occasional bit of candy or french fries but these types of items are not staples in her diet. Initially she wasn't that crazy about the changes in her diet but now she likes what I make. More importantly she is learning to make good food choices on her own.
