Obese Patients Unlikely to Return to Normal Weight

Fewer than 1% of obese people will attain normal weight, a new study suggests.

Those chances are about 1 in 210 for obese men and 1 in 124 for obese women. And the news is even worse for those who are extremely obese: for them the chances of bringing BMI values into the normal range are 1 in 1,290 for men, and 1 in 677 women.

But chances of achieving clinically significant weight loss, at least 5% of body weight, in the morbidly obese were somewhat better although still low: 1 in 8 for men and 1 in 7 for women.

This study involved data from more than 75,000 men and nearly 100,000 women who hadn't undergone bariatric surgery and who were followed for up to 9.9 years.

"Our findings indicate that current nonsurgical obesity treatment strategies are failing to achieve sustained weight loss for the majority of obese patients," wrote the authors. "These findings raise questions concerning whether current obesity treatment frameworks, grounded in weight management programs accessed through primary care, may be expected to achieve clinically relevant and sustained reductions in BMI for the vast majority of obese patients and whether they could be expected to do so in the future."

The proportion of participants that showed no change was greatest for the normal weight category (57% of men and 59% of women); it decreased as baseline BMI increased, with the exception of the super-obese with a BMI over 45 kg/m2. Only 14% of men and 15% of women showed a decrease in a BMI category without also showing an increase in the same period.

Of those who did achieve 5% weight loss, 53% regained the weight within 2 years and 78% had regained it within 5 years, according to the study. Probability of achieving the weight loss increased as BMI categories increased. For both men and women, 12% recorded only BMI increases.
