Hi Amy, welcome to FitDay. Everybody starts somewhere; congrats on making the decision to get healthier. We are glad to have you along and hope you feel free to jump into the forums and get to form some connections. You can post in any forum, but you might want to take a look at the 100+ pounds to lose in the Weight Loss section and also the 7-Day Motivational thread in the Women's Corner.
Also, I can share from experience that with practice, you don't have to be cooking separate meals for yourself and your family. One of our members here once said "what's good for the goose is good for the gander," explaining that if you're going to eat healthy, then your kids will benefit from that, too. A lot of times, with some thought, you can cook and eat basically the same thing with modifications. For example, if I make tacos for the family, I have my (usually chicken) in a huge salad instead of in taco shells. If I'm cooking a turkey and making mashed potatoes, I'll just stick in a sweet potato for myself...things like that. I've been at this game a long time and one thing I know is that "diet" food doesn't cut it for me; I needed to learn to work with real food. Many of us here have been that route, so if you ever need suggestions or want some advice, post it somewhere and I promise you'll get some thoughts. Shoot, I could talk about food all night!
Check out the threads in the Food section...great place to start
