I do something similar to the google image searching the fat people. When I have cravings like this, I go on facebook and look through the photos of my overweight friends who never get laid. Looking at google images of the world's fattest man is very abstract, and it's too easy to just see him as a distant, ridiculous character. Look at real people who have weight problems that harm their social lives, like people from your classes or work or whatever who have friended you for some reason. Real photos of real far people I have contact with are always guaranteed to scare me into being healthy.
(Note: make sure you look through the photos that other people have tagged, not the ones that this person has tagged of himself or herself, as this person probably only tags photos that creatively downplay and distort his or her true appearance.)
