I look a bit overweight in photos. Help!

OK, we've all encountered this issue at one time or another and Elements has the solution: the Liquify Filter! (Quick or Advanced > Filter > Distort > Liquify).

At right: Here I used Liquify's Shift Pixels Brush Tool to give the model a more shapely curve under her chin. A little adjustment goes a long way. Liquify sort of treats pixels like wet oil paint that can be pushed back and forth for the perfect weight loss and beautification result.
