When you finally get five minutes to yourself, updating your Facebook status is way more tempting than looking up calorie counts, right? The good news is that tech-loving moms everywhere can log on and slim down at the same time -- for free! Check out our favorite apps and websites that make dropping pounds easier than ever.
If you're an iPhone lover
How it works: This app calculates how many calories you're taking in and burning off daily. Every time you eat something -- from a carrot to a mocha -- enter the name of the food and the portion size to see how much of your daily calorie budget's left.
If you're a web-surfing whiz
How it works: Snag some 'net inspiration from the 50 Million Pound Challenge hosted by Ian Smith, M.D. (don't worry -- that's how much he wants the whole country to lose!). Joining gets you a 30-day meal plan, complete with shopping lists, healthy snack ideas, and even videos of the hot doc himself.
If you're an online chatterbox
How it works: Biking champ and cancer survivor Lance Armstrong created this site to inspire people to achieve healthy goals -- from weight loss to quitting smoking. You'll find exercise videos and a supportive community who cheers you on as you tackle challenges like "Do 100 pushups by 2010" or "Eat fewer carbs."
If you're a Facebook fanatic
How it works: While you're catching up with your junior-prom date and playing Scramble, you can also track your fitness goals by adding a cute ticker to your home page. Upload a design to your Facebook page; plug in your workout regimen or weight-loss goals, and update it anytime for an instant reminder of how far you've come.
