Hey Skinny!
Yes - take control! It's time.
For advice - head on over to the Weight Loss Support or Goals forums and read, read, read! Tons of stories, tons of advice, and tons to keep you going.
For people who don't know where to start, I always suggest babysteps. What can you do tomorrow that you didn't do today? Get 8 servings of produce? Drink 8 glasses of water? Take a 30 minute walk? Pick one or two, and do them for a week.
After that week, add another babystep. Then another. Before you know it, you have a healthy, weight-loss-friendly lifestyle that will carry you through weight loss and into maintenance.
Stick around, ask questions, read, and post. Can't wait to get to know you better.
