That too online?
Answer is WeightMirror. It is an instant weight-loss or gain simulation and makeover tool that will show you what you would look like if you lost or gained weight within seconds.
All you have to do is three simple things:
1. Upload your photo(full-body frontal photo recommended).
2. Enter your current weight and height in lbs.
3. Choose the desired weight using a slider. It has a BMI(Body Mass Index) indicator too.
And you are done. Your photo will be modified and showed next to your original to know how you will look if you achieved your desired weight.
You can do some edit in your final photo like rotate, zoom, adjust brightness and contrast etc.

They have also made a iPhone app for WeightMirror which costs $2.99 and is available in the app store. It carries a BMI calculator, automatic face detector etc.
