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.

Having A Muscular Body Can Increase Your Longevity

"Rising from a chair in old age and kicking a ball depend more on muscle power than muscle strength, yet most weight-bearing exercise focuses on the latter"

The highest value achieved after two-three attempts with increasing loads was considered the maximal muscle power and expressed relative to body weight. Values were divided into quartiles for survival analysis and analysed separately by sex. Pixabay

Want to increase your longevity? If yes, then speed up your weight-lifting routine as a new study suggests muscle power might be key to long life.

The study, presented at the EuroPrevent 2019 in Lisbon, indicates that power depends on the ability to generate force and velocity and to coordinate movement.

“We now show that power is strongly related to all-cause mortality. But the good news is you only need to be above the median for your sex to have the best survival, with no further benefit in becoming even more powerful,” said Araújo. Pixabay

“Rising from a chair in old age and kicking a ball depend more on muscle power than muscle strength, yet most weight-bearing exercise focuses on the latter,” said study author Claudio Gil Araújo, Professor at Exercise Medicine Clinic — CLINIMEX in Rio de Janeiro, Brazil.

“Our study shows that people with more muscle power tend to live longer,” Araújo said.

For the study, the team enrolled 3,878 non-athletes, aged 41-85 years, who underwent a maximal muscle power test using the upright row exercise between 2001 and 2016. The average age of participants was 59 years, five per cent were over 80 and 68 per cent men.

The highest value achieved after two-three attempts with increasing loads was considered the maximal muscle power and expressed relative to body weight. Values were divided into quartiles for survival analysis and analysed separately by sex.

During a median 6.5-year follow-up, 247 men (10 per cent) and 75 women (6 per cent) died, according to the study.

Muscle power start decreasing after 40 years of age.

“We now show that power is strongly related to all-cause mortality. But the good news is you only need to be above the median for your sex to have the best survival, with no further benefit in becoming even more powerful,” said Araújo.

The researchers suggest multiple exercises for the upper and lower body, weight with the load to achieve the maximal power (not so easy to lift and not so heavy that you can barely lift it) may increase muscle power. (IANS)
