As it was my tradition, in December I rebuild the old favorites from years gone by. This year I'm looking into 2015.
If I looked at 279,000 men and women for a decade and I was studying whether or not they came for the Boston Marathon but did not really want to see if they were runners and if they were runners I did not bother to find out what the training plans and distances were like, looked at how many of those 279,000 qualified in Boston, I suppose I would stay with an incredibly small number.
And yet, that's exactly what the latest weight loss depression study did. There followed 279,000 men and women for ten years to see what was the chance of losing obese people back to "normalweight (a BMI less than 25) do not exclude people who did not try to lose weight or who did not want to lose weight but paid no attention to the means by which those who did lose weight only to regain their loss in first class.
Chances were not good. Over a decade, only 1 in 210 men with obesity and one in 124 women managed to bring their weights to a point where a table would describe them as "normal".
It's not very strange. Leaving aside the surprising fact that this study does not exclude people who were not trying to lose weight, it remains that the vast majority of people who are trying to lose weight these days do this by making ridiculous diets. Go the number of people do not support the results of ridiculous diets; The weight you lost from the suffering comes when you get out of hassle. This study, of course, loses all that.
And it reaches a "normal"Weight really the right criterion for measuring success? I want to go down to a BMI under 25 is the weight loss what is qualified for the Boston Marathon is to run regardless of whether the people were runners or not.
But what if you change the positions of the goals?
If, for example, you started studying the number of runners that continue to enjoy as often and as much as they can enjoy, and not just the number of runners selected for Boston, suddenly the number of runners will be much higher, although of course not everyone who starts to run, keep up with it either.
Extending that for weight, if the target positions become "better weight"which is the weight you get when you live the healthiest life you can enjoy, suddenly the numbers change.
How are they changing?
Looking at, for example, the 8 years of the LOOK AHEAD study, where lifestyle changes were thoughtful and the target was not fit for Boston, 8 years out and 1 out of 2 participants lost more than 5% their presentation weights and more than 1 in 4 have lost more than 10%.
Did the publication of this depressive study also contribute to the literature of obesity? Quantification of the number of people who do not qualify for the Vaoton Weight Loss Marathon without counting how many of them were actually runners and what type of training program they adopted does not consider me to be a useful addition.
I can also ask myself what the impact of publishing and the coverage of such studies as they have on people who may be considering lifestyle changes – both in terms of enhancing foolish goals and on the part of starting from the gates.
