Every time I sit at the computer to write, either a child needs a snack (stat!)--in fact, this very second, my daughter just asked me for "fishy crackers"--or the phone rings or I remember something urgent I must do (like cancel the auto insurance policy on the van we haven't owned since July 4).
Or a kid comes in to say, "Hey, Mom, I wish we could remove the white things on the ceiling," (we have popcorn-textured ceilings which apparently are problematic now that we have bunk beds). Or someone says, "Hey, Mom, he took my turn." You know. Important stuff.
This morning, I spent quite a bit of time doing a Google search in an attempt to track down the origin of that oft-heard statistic: "Ninety-five percent of diets fail" and "Ninety-five percent of all dieters regain their weight," and "Ninety to ninety-five percent of people who diet to lose weight gain most of the weight back within three to five years." Where, oh, where did this bit of information originate? Is it true?
As it turns out, a couple of researchers back in the 1950s studied one hundred obese dieters in treatment and came up with this conclusion: ''Most obese persons will not stay in treatment, most will not lose weight, and of those who do lose weight, most will regain it.'' They decided this because of their one hundred dieters, only two of them kept off their weight. Thus, a statistic was born.
Jane Fritsch of the New York Times wrote an article addressing this very issue ("Is that dismal statistic true? From whence did it come?") which was published on May 25, 1999. You can read it here.
If you don't read the whole article, you should at least know this:
''That 95 percent figure has become clinical lore,'' said Dr. Thomas Wadden, a professor of psychiatry at the University of Pennsylvania. There is no basis for it, he said, ''but it's part of the mythology of obesity.''
That's right, folks! It's just not true that "95% of diets fail." It's not true that 95% of dieters will regain all their weight within three years. It's not true that dieting is pointless. The people at the National Association to Advance Fat Acceptance, Inc. will try to convince you of this:
Just being fat does not signify poor health. In fact, research shows that the health risks once associated with weight may instead by attributable to yo-yo dieting. Because fatness is most often caused by heredity and dieting history, and because 95-98% of all diets fail over three years, it is becoming apparent that remaining at a high, but stable weight and concentrating on personal fitness rather than thinness may be the healthiest way to deal with the propensity to be fat."
That statistic ("95% of diets fail over three years") is everywhere and yet, it's not accurate. I found an article from American Journal of Clinical Nutrition this morning that cited research showing a specific breakdown. For instance, the article reported that individuals maintained 67% of their initial weight loss at one year, 44% at 2 years, 32% at 3 years, 28% at 4 years, and 21% at 5 years. (It was all full of mumbo-jumbo, but I did find a lot of interesting information at that particular site, if you are interested in academic research and can wade through a bunch of incomprehensible acronyms.)
I did figure out, though, that this study concludes:
In conclusion, this meta-analysis of 29 reports of long-term weight-loss maintenance indicated that weight-loss maintenance 4 or 5 years after a structured weight-loss program averages 3.0 kg [6.6 pounds] or 23% of initial weight loss, representing a sustained reduction in body weight of 3.2%.
Do you see "ninety-five percent of diets fail" mentioned at all? No. Sure, the people who lost weight through a structured weight-loss program did (on the average, but not ninety-five percent of them) gain some of their weight, but (on average) they maintained twenty-three percent of their initial weight loss. Some maintained more, some maintained less, but overall, on average, they maintained twenty-three percent of the loss.
Furthermore, the studies on weight-loss maintainance have been done using people who were using a structured weight-loss program. The rest of us, the ones who are merely eating less, eating smarter and moving more? Maybe we're just too complicated to study and track in the long-term.
Now, the people over at the National Weight Loss Registry list some research findings of their own, including this "descriptive study of individuals successful at long-term maintenance of substantial weight loss" which mentions, "Surprisingly, 42% of the sample reported that maintaining their weight loss was less difficult than losing weight."
I would include a link here about how important exercise is in maintaining a weight loss, but the children are running amok (my four plus three extras) and my eardrums have just ruptured. But suffice it to say, that if you intend to maintain your weight loss, you must embrace exercise as a necessary part of your life, like, say, oxygen.
Personally? I have completed my first week of exercise streaking. And if these kids don't settle down, I just might take up running . . . away from home.
