Researchers studied nine years of data from more than 150,000 obese and morbidly obese adults to see how many of them were able to regain normal weight. That’s a huge study, over a time period that allows for lots of potential variables. The result? Virtually no one managed to regain a normal weight, after almost 10 years.
The researchers analyzed records of people 20 years and older from the United Kingdom’s Clinical Practice Research Datalink (CPRD) from 2004 to 2014, they reported in the American Journal of Public Health. They looked at data for more than 76,000 obese men, and nearly 100,000 obese women. They excluded people who’d received bariatric surgery. To be included in the study, at least three BMI records had to be in the medical record from 2004 to 2014.
What the researchers found was that, during that nine-year time frame, only 1,283 men and 2,245 women attained normal body weight. Just 1 of every 210 men gained a normal weight, and 1 of every 124 women did so.
Diets didn’t help. Weight loss programs didn’t help. Constant exercise didn’t help. In short, nearly all of the obese adults didn’t regain normal weight, thereby assuring that they would likely trigger an epigenetic change for future generations.
==========================================
The researchers suggested that answers to the obesity epidemic may, in fact, lie outside the primary healthcare world.
If normal weight reduction is rare, then solutions to the problem may lie in other areas (like popular advertising campaigns that sway people toward certain types of foods, for instance).
“In the absence of effective interventions targeted at the individual level, the greatest opportunity for tackling the current obesity epidemic may be found outside primary care,” they wrote. “
Research to develop wider reaching public health policies is needed to prevent obesity at the population level.”
