Virtual plastic surgery games are still rare online but show great potential for mass popularity. The idea that we can see what we might realistically look like after plastic surgery is of great interest to even many people who would never consider plastic surgery in real life.

Unfortunately these virtual games are still very basic and childish and will not give you realistic before and after images. The best you can expect is some entertainment value. But here's two of the most popular ones to check out;

Researchers at Standford University have found that people who are trying to lose weight will be more successful if they see their own virtual model losing weight.

The Virtual Human Interaction Lab created sophisticated virtual model images of their test subjects and then showed them these models on a treadmill getting slimmer and slimmer. They also showed them their own virtual model getting fatter as they ate junk food.

The tests showed that people were very motivated by these sophisticated 3D models that looked just like themselves. The majority of participants exercised more often after having seen this virtual weight loss simulation.

Hear an interview about this at NPR radio.

We can't wait for this sophisticated tool to get out of the lab and become available for general use. Until then though, you can always try our virtual weight loss model here.
