In a five-year weight loss study, half of the significantly overweight participants weighed themselves once a week, while the other participants never weighed themselves. All of the participants had the same diet and exercise plan. After five years, the individuals who weighed themselves once a week maintained their weight loss much more often than those who did not.
Which of the following, if true, most helps to explain the study’s finding?
Explanation
Answer: B - If the participants who weighed themselves found it motivational to see their progress, making them less likely to cheat on their diet and exercise plans, it explains how, despite following the same diet and exercise plan, participants who weighed themselves were more likely to be successful at weight loss than others due to improved motivation, a direct result of regular weigh-ins.
