But isn't bariatric surgery cheating?

How We Did It got a nice mention in my local newspaper yesterday, The Times of Trenton. It's an article about a local woman who underwent bariatric surgery and lost over 100 pounds.

"But isn't that cheating?" you ask.

That's what I thought before I started to talk to people about weight loss surgery.

One well-known bariatric surgeon, Dr. Scott Shikora, chief of general surgery and bariatric surgery at Tufts Medical Center in Boston, says that realistically speaking, fewer than 10 percent of morbidly obese people will ever achieve weight loss without surgery. Those are some pretty bad odds.

The problem is that when obese people modify their diet, their bodies fight the perceived starvation. They try to exercise, but their weight and overstressed joints prevent them from accomplishing meaningful movement. It's a classic catch-22.

When excess weight reaches the point of endangering a person's health, sometimes surgery is the only possible way to bring them back from the brink of death. So, a person who carries 100 pounds over their ideal weight and has diabetes or high blood pressure may become a good candidate for the surgery.

In many ways, undergoing weight loss surgery requires the same commitment to diet and exercise as the person who chooses a weight loss plan. Eating is strictly controlled and a specific eating plan must be followed in order to prevent complications and weight regain. Exercise is encouraged as part of the patient's new, healthy lifestyle.

But of course weight loss surgery carries significant risks. One of the people in How We Did It who lost 120 pounds after gastric bypass surgery suffered several complications that put her back in the hospital. Yet, today, she is able to maintain her loss and rarely has side effects. But anyone considering weight loss surgery will, of course, have indepth discussions with his or her doctor. Most will also attend mandatory group sessions to determine whether they have the level of commitment necessary to make the surgery and its risks worthwhile.

Although she considered it her last resort, the woman profiled in my local newspaper, Georgette Brown, believed her surgery to be absolutely necessary. She has lost more than 100 pounds and is wearing a size 8, where once she weighed 283 pounds. Congratulations, Georgette!

The ghrelin monster

A woman I interviewed for How We Did It said something striking to me. Deb Anderson had bariatric surgery -- a procedure called duodenal switch that reduces the size of stomach and creates a system in which the nutrients of food aren't entirely absorbed by the body, so the calories in it aren't either.

Deb went on to lose 140 pounds after the surgery. She went out one night to a Cracker Barrel and when it came time for dessert, she ordered a "buckeye." Now, for those of us in the Northeast, a buckeye is a chocolate-covered peanut butter nugget. Before the surgery, Deb admitted she could eat half a dozen of them easily. But on this night, she ordered one, cut it in fourths and ate only one quarter of the buckeye.

This wasn't a supreme act of will. Deb says she just didn't want the same foods in the same amount as she did before the surgery. She craved fruits and veggies, not fried foods and sweet desserts. Here's how she puts her surprising discovery of the change:

"I thought, Gee, did he do surgery on my brain or my stomach?"

It turns out, the surgeon just might have done surgery on both!

I was reading an article by Dan Hurley in Discovery magazine last night, The Hungry Brain. In the article he talks about a study showing that people who have had weight loss surgery have an easier time maintaining their loss than those who lost weight through diet and exercise.

That really surprised me! Turns out, surgery not only reduces the size of the stomach but it decimates the stomach's amount of an appetite inducing hormone called ghrelin. Those who lost weight through surgery saw their ghrelin levels plummet. The conventional weight losers saw their ghrelin levels skyrocket in direct proportion to how much weight they had lost -- the more lost weight, the higher the levels of ghrelin and the greater their appetite.

This explains a LOT. It explains why it's so hard to maintain a loss. It's not just a matter of willpower. Deb had lost and regained weight many times. "I'm smart," she said, "but I just couldn't outsmart it."

I have to be honest and say that most people who talked to me about regaining their weight in their past failed attempts to diet did so because they went back to their old habits. Environment -- the endless food cues and opportunities that bombard us every day -- plays a huge role in maintaining a weight loss. You have to remain vigilant and fight the daily urges that arise from your environment.

It's not as grim as it sounds. Like Deb, I found my desires changed over time. The food messages don't get through as often as they used to. But this new research into appetite hormones might just lead to something someday and give us all a better chance at maintaining a hard-won weight loss.
