A Cheek Swab to Choose Your Diet Plan? – Yahoo! News


Have you ever wondered why your best friend had no problem dropping pounds on Weight Watchers, while you stuggled over every ounce, even though you were eating exactly the same things?  Or why some people drop weight on the Atkins diet, while others actually gain?  Maybe it’s your genotype.

The link to the article below is the most interesting study I have read on weight loss in a long time.  The study assigned dieters to a particular diet (low-carb, low-fat, etc.) based upon their genotype, which was determined through a cheek swab.  The dieters who were “eating right for their type” lost significantly more weight on the same diet than those who were not. 

You may remember Dr. Peter D’Adamo’s Blood Type Diets, which recommended diets based on your blood type.  Although some dismissed the science behind it, the idea that we respond to foods differently based upon our genetics certainly makes sense.

When I worked as a nurse in a medically-supervised weight loss clinic in the late 90’s, it bothered me when clients who were not losing weight on the standard ADA diet (this clinic also prescribed fen-phen) were labled as non-compliant.  The assumption made by the doctors was that everyone, male or female, young or old, would respond in the same way to the same plan.  A calorie deficit would absolutely result in weight loss, and anyone who said they were following the diet yet not losing weight was simply lying about their intake.  I always knew instinctively that this was not necessarily the case.

The weight loss industry has a dismal track record; the majority of people who lose weight will gain it back at some point.  While there are many success stories, the Kirstie Alley’s and Oprah’s of the world are more the rule than the exception.  It is unfortunate that they continue to beat themselves up, as if gaining the weight back was some kind of moral failing.  As long as we continue to look at dieting as a one-size-fits-all plan and failure is looked upon as a character flaw, we will continue to see a rise in obesity.  When we begin to look at obesity as being a symptom of an underlying medical condition which may differ from individual to individual, we will begin to see progress.  Further research on genotypes, brain chemistry, and the individual chemical responses we have to food will pave the way to a much healthier diet paradigm.

I invite you to read this article on some preliminary reseach on genotyping for diet:
