A new study conducted by researchers from the Loyola University in the US says that exercise may not help you keep those extra kilos at bay, contradicting the belief that lack of physical activities or increased sedentary time is linked to obesity. The study says that while physical activity burns calories, it also increases appetite and people may compensate by eating more or by being less active the rest of the day.
Speaking about this, the researchers said, Our study results indicate that physical activity may not protect you from gaining weight. Some experts have suggested that a decline in physical activity, especially in the workplace, has been a key contributor to the obesity epidemic.
Researchers followed adults aged 25 to 40 living in five countries: the US, Ghana, South Africa, Jamaica and Seychelles. They measured participants` weight, height and body fat. After an initial exam, participants were asked to return one year and two years later. At the initial visit, Ghana participants had the lowest average weights (63 kilogrammes for both men and women), and Americans the highest weights (91 kilogrammes for women, 93 kilogrammes for men).
Surprisingly, total weight gain in every country was greater among participants who met the physical activity guidelines. Researchers did not find any significant relationships between sedentary time at the initial visit and subsequent weight gain or weight loss. The only factors that were significantly associated with weight gain were weight at the initial visit, age and gender.
