FitnessMantra Weekend: Rethinking Thin - Is Obesity A Purely Inherited Condition?

Welcome to “FitnessMantra Weekend”, your once-a-week health news update. As always you can also stay updated with the latest in fitness news by subscribing separately to the Fitness Mantra del.icio.us feed.
On average I bookmark about 25 interesting health and fitness related articles each week and in most cases I skim through the article and can grasp the gist of it. 
This week’s highlighted article, however, was an exception. I actually read through it twice to understand the implications and while many of the theories expounded seemed to make sense and I had read similar articles in the past that hinted at this conclusion, it was still a tough pill to swallow and see more conclusive evidence: being obese or overweight could be a purely inherited condition.
Genes Take Charge, and Diets Fall by the Wayside is the attention-grabbing New York Times article I speak of. It describes the experiments conducted by Dr. Jules Hirsch of Rockefeller University who had set out in 1959 to find out more about the effects of weight loss on obese. I urge you to read the 2-page article completely so you can understand how Dr. Hirsch came to this startling conclusion: As the obese lost weight, their metabolism also started to slow and their mental outlook became similar to that of normal people who were suddenly starved.:
The Rockefeller researchers explained their observations in one of their papers: “It is entirely possible that weight reduction, instead of resulting in a normal state for obese patients, results in an abnormal state resembling that of starved non-obese individuals.”
But if you thought that the result was as simple as that and once people got fat they could almost ever lose that weight again, then you are in for more food for thought: the reverse was true too! Thin people who gained weight by unnaturally compulsive eating spiked their metabolism (by almost 50%) to the point where it became really difficult to keep the weight on! After the study this second group of (naturally thin) people had no difficulty shedding the weight they gained during the study.
Then in the 1980s, Dr. Albert Stunkard of the University of Pennsylvania performed a study that showed that adopted children assumed a particular body-type and weight at adulthood that had more to do with who their biological parents were than with their eventual adoptive environment or even what they ate during their childhood growing up! The startling result is succinctly summed up as: 80 percent of the offspring of two obese parents become obese, as compared with no more than 14 percent of the offspring of two parents of normal weight.
Think it’s easy for that fat person to lose weight? Just eat less and exercise more, you say? Dr. Jeffrey Friedman, an obesity researcher at the Rockefeller University has this to say about the matter:
“The feeling of hunger is intense and, if not as potent as the drive to breathe, is probably no less powerful than the drive to drink when one is thirsty. This is the feeling the obese must resist after they have lost a significant amount of weight.”
Gina Kolata is the author of Rethinking Thin: The New Science of Weight Loss-and the Myths and Realities of Dieting, an eye-opening book that describes the futility of overthinking weight-loss and why, after a certain point, pure genetics could take over what you will finally weigh. The studies above and more are included in her book which talks about issues at the very core of the multi-billion-dollar weight-loss industry in the United States and the rest of the world.
Fat Chance is an article that reviews the book and offers highlights from it. You can read the first chapter of Rethinking Thin on the New York Times website or buy the book from Amazon.
So what does this mean for the millions of people trying to lose weight? Just sit back on the couch, tear open that chips-packet and blame your parents? Not a chance - that will only make a bad situation worse. The rules of calorie balance apply to everyone and they can lose weight using that very same regimen of eating less than they expend and including a well-balanced exercise program.
Granted, this entire blog post tells us it’s going to be more difficult for them to keep the weight off, but then isn’t that what mental-discipline is all about?
