Self Image: Who's That Thin Person in the Mirror? (cont.)

What's more, says Aronson, the longer you have lived with your plus-sized image, the harder it may be to ditch behavior and responses that had become automatic.

"If you continually avoided certain situations fearing humiliation because of your size, you unknowingly created a pattern of thinking that, over time, gets imbedded in your brain," says Aronson, author of The Final Diet. "It can be hard to let go of this kind of conditioning, even after you reach your goal weight."

In Search of a New Self-Image

That was the case for Lisa Goezte, a one-time chronic overeater who once tipped the scales at 550 pounds. Even after "stomach-reducing" surgery at New York-Presbyterian Hospital/Columbia helped her lose more than 350 pounds, it took some time before her new self-image kicked in.

"I had people consistently telling me that I was losing weight, but it was bizarre because I never saw it. I was so used to seeing myself in the mirror looking a certain way, that this was the image I continued to see," says Goezte, now a personal trainer at Can Do gym in Edgewater, N.J.

Even as she approached her goal weight, she stuck with dark colors and baggy clothes, and tried to hide her body as much as possible, she says. It wasn't until she won certification as a personal trainer that her mind began to catch up with what her body had accomplished.

"The fitness world is place of perfect bodies, and when I began to see that I was accepted there, in that world, I began to look at myself differently," says Goezte, who admits she still occasionally has a day when the woman in the mirror seems larger than life.

Passing for Thin

While liking the image you see in the mirror is a good start, you may not be mentally "fat-free" If you've been battling the bulge for any significant amount of time, says Los Angeles psychologist and body image expert Yvonne Thomas, PhD.

"Reacting as if you are still fat -- or what being fat means to you -- can become a natural reflex, driven by the subconscious, and capable of influencing our behavior in ways we sometimes don't see," Thomas tells WebMD.

That means you may often find yourself in an emotional tug-of-war between the person you are now and the one you used to be, she says.

"We may think we are reacting to our life in the here, but in reality, every day is like walking through a minefield of emotional, and sometimes, humiliating memories of what we endured when we were overweight," says Thomas.

In her new book Passing for Thin, author Frances Kuffel -- once 338 pounds and now a svelte size 10 -- details this very experience.

"If you have a friend or family member you really trust, have them take a picture of you in a bathing suit."

"It is hard to put that humiliation you felt as an overweight person behind you, partly because, I think, that at least some of the problems that caused you to overeat are probably still with you," says Kuffel. "You don't automatically lose those when you lose the weight."
