Exercise May Lead To Weight Gain, Not Loss, Study Finds

CHICAGO — Regular exercise is believed by many as the key to losing weight, but a new study suggests otherwise.

Researchers at Loyola University Chicago in Illinois recently released research conducted upon young adults, aged 25 to 40, in five countries: the United States, South Africa, Jamaica, Ghana, and Seychelles. 

Researchers found weight loss doesn’t hinge on physical fitness, and may even cause some to gain more weight.

Using tracking devices to measure participants’ activity, each participant also had their height, weight, and body fat recorded during an initial exam. They would participate in two follow-up exams in annual increments. These subsequent exams revealed that for each country examined, those who participated in moderate-intensity aerobic exercise for at least 150 minutes a week actually gained slightly more weight than those who did not.

(The 150 minute yardstick is actually a guideline recommended by the U.S. Surgeon General.)

“Our study results indicate that physical activity may not protect you from gaining weight,” Lara R. Dugas, lead author of the study, said in a release.

Though physical fitness can help prevent ailments such as heart disease and diabetes and improve mental fitness by boosting one’s mood, the researchers determined “it also increases appetite, and people may compensate by eating more or by being less active the rest of the day.”

This study also suggests that a sedentary lifestyle the inverse of being activehas no direct correlation with weight gain. A fair question then may be: what does?

The researchers concluded that the best predictors of weight gain were age, the participants’ weight at the initial visit, and gender.

Americans may very well rejoice in this fatalistic news of sorts, as they were found to not only be the heaviest of the five nationalities on average, but reported exercising much less than participants from other countries.

The study is published in the journal PeerJ.
