Thanks to the popularity of books like The Secret and Law of Attraction, the power of positive thinking and visualizing is no longer—pardon the pun—a secret. In fact, experts say visualizing is especially helpful when it comes to weight loss.

Keeping that in mind, do you need a little positive reinforcement with a certain weight-related resolution you made at the beginning of the year? Our new body makeover tool just might be able to help. Upload a picture, input your current height and weight, then adjust your size to anywhere within your healthy BMI range. Regardless of whether you want to put on a few pounds or drop twenty-five, you can see the results shape up as nicely (and as quickly!) as Heidi Klum's post-baby bod.

Try it out with pics of yourself in different outfits and save your favorites. Even better: stick the before and after shots on a mirror or your fridge for a daily dose of inspiration. Then, don't forget to visit our health and fitness section for exercises and advice on how to put that motivation to work so you can start seeing those results both on and off the screen. After all, seeing is believing!
