Discuss about Walking's Effects on Weight Loss From the Media's Point of View

While walking more does decrease sedentary time, which has its own health benefits, it does notnecessarily lead to weight loss. AFPDespite the common belief that we should all be walking 10,000 steps a day, new American research has found that walking more may decrease your sedentary time, but it doesn't actually prevent weight gain.Carried out by researchers at Brigham Young University, the new study looked at 120 first-year students during their first six months of college, splitting them into three groups to investigate whether increasing the number of daily steps above 10,000 would prevent weight and fat gain.

While one group of students was asked to walk 10,000 steps a day for six days a week over a period of 24 weeks, another group was asked to walk 12,500 steps a day, and a third, 15,000 steps a day.The participants were asked to wear pedometers 24 hours a day to track their steps. The researchers also tracked the participant's caloric intake and weight.

The findings, published in the Journal of Obesity, showed that while the students walked approximately 9,600 steps per day on ave-rage before starting the study, those in the 10,000-step group managed to average 11,066 steps a day by the end of the study.Those in the 12,500-step group averaged 13,638 steps and those in the 15,000-step group averaged 14,557 steps a day.However, no matter how many steps the students walked, they still gained weight, even if they were in the 15,000-steps-a-day group.

The participants gained on average about 1.5kg over the course of the study period, with the researchers noting that a 1-4kg average weight gain is common during the first year of college, according to previous studies.Exercise alone is not always the most effective way to lose weight, said lead author Bruce Bailey.

If you track steps, it might have a benefit in increasing physical activity, but our study showed it won't translate into maintaining weight or preventing weight gain. However, one positive finding is that walking more did help boost physical activity levels, which may have other emotional and health benefits, the study authors said. Unsurprisingly, walking more significantly reduced sedentary time in both the 12,500- and 15,000-step groups, and by as much as 77 minutes a day in the 15,000-step group.

The biggest benefit of step recommendations is getting people out of a sedentary lifestyle, said Bailey.

Even though it won't prevent weight gain on its own, more steps (are) always better for you. AFP Relaxnews
