London: Casting aspersions on the effectiveness of current weight management programmes focused on dieting and exercise, it has been found that chances of obese people recovering normal body weight are very slim, shows research. 3829063385_8e46d16540_o

The chance of an obese person attaining normal body weight is one in 210 for men and one in 124 for women, increasing to one in 1,290 for men and one in 677 for women with severe obesity, the findings showed.

“Once an adult becomes obese, it is very unlikely that they will return to a healthy body weight,” said study’s first author Alison Fildes from the University College London.

The findings suggest that current weight management programmes focused on dieting and exercise are not effective in tackling obesity at population level.

The research tracked the weight of 278,982 participants (129,194 men and 149,788) women using electronic health records from 2004 to 2014.

The study, published in the American Journal of Public Health, looked at the probability of obese patients attaining normal weight or a five percent reduction in body weight. Patients who received bariatric surgery were excluded from the study.

The annual chance of obese patients achieving five percent weight loss was one in 12 for men and one in 10 for women.

For those people who achieved five percent weight loss, 53 percent regained this weight within two years and 78 percent had regained the weight within five years.

Overall, only 1,283 men and 2,245 women with a body mass index (BMI) of 30-35 reached their normal body weight, equivalent to an annual probability of one in 210 for men and one in 124 for women.

For those with a BMI above 40, the odds increased to one in 1,290 for men and one in 677 for women with severe obesity.

Weight cycling, with both increases and decreases in body weight, was also observed in more than a third of patients.

“This evidence suggests the current system is not working for the vast majority of obese patients,” Fildes said.

Gaining Weight After Quitting Cigrattes, Still Better In the Long Run: Study

Regardless of the amount of weight gain, quitters always have a lower risk of dying'' prematurely.

If you quit smoking cigrattes and gain weight, it may seem like you’re trading one set of health problems for another. But a new U.S. study finds you’re still better off in the long run.

Compared with smokers, even the quitters who gained the most weight had at least a 50 percent lower risk of dying prematurely from heart disease and other causes, the Harvard-led study found.

The study is impressive in its size and scope and should put to rest any myth that there are prohibitive weight-related health consequences to quitting cigarettes, said Dr. William Dietz, a public health expert at George Washington University.

“The paper makes pretty clear that your health improves, even if you gain weight,” said Dietz, who was not involved in the research. “I don’t think we knew that with the assurance that this paper provides.”

The New England Journal of Medicine published the study Wednesday. The journal also published a Swedish study that found quitting smoking seems to be the best thing diabetics can do to cut their risk of dying prematurely.

10 pounds or more

The nicotine in cigarettes can suppress appetite and boost metabolism. Many smokers who quit and don’t step up their exercise find they eat more and gain weight — typically less than 10 pounds (4.5 kilograms), but in some cases three times that much.

A lot of weight gain is a cause of the most common form of diabetes, a disease in which blood sugar levels are higher than normal. Diabetes can lead to problems including blindness, nerve damage, heart and kidney disease, and poor blood flow to the legs and feet.

In the U.S. study, researchers tracked more than 170,000 men and women over roughly 20 years, looking at what they said in health questionnaires given every two years.

The people enrolled in the studies were all health professionals, and did not mirror current smokers in the general population, who are disproportionately low-income, less educated and more likely to smoke heavily.

The researchers checked which study participants quit smoking and followed whether they gained weight and developed diabetes, heart disease or other conditions.

Quitters saw their risk of diabetes increase by 22 percent in the six years after they kicked the habit. An editorial in the journal characterized it as “a mild elevation” in the diabetes risk.

Studies previously showed that people who quit have an elevated risk of developing diabetes, said Dr. Qi Sun, one the study’s authors. He is a researcher at the Harvard-affiliated Brigham and Women’s Hospital.

But that risk doesn’t endure, and it never leads to a higher premature death rate than what smokers face, he said.

“Regardless of the amount of weight gain, quitters always have a lower risk of dying” prematurely, Sun said. (VOA)
