Study: Probability of obese people reaching "normal" weight is less than 1%

The Centers for Disease Control classify a BMI of between 25 and 29.9 as “overweight,” anything above that as obese.

Nine years worth of data for 76,704 obese men and 99,791 obese women from the United Kingdom was analyzed by researchers from King’s College London, who found that the annual probability of reaching a normal weight was less than 1 percent for both groups — just 1 in 210 for obese men and 1 in 124 for obese women (obese = 30.0–34.9 BMI).

For those with morbid obesity (BMI = 40.0–44.9), those odds decreased to 1 in 1,290 for men and 1 in 677 for women.
