GOD WANTS YOU TO LOSE WEIGHT
Can you convince people to exercise and eat more fruits and vegetables by telling them it’s what God wants? An intervention at Middle Tennessee State University is doing exactly that, with excellent results. The intervention asks people to consider how self-care and health are important values in their religion. For example, Christians may be asked to reflect on passages from the Bible such as “Do not join those who drink too much wine or gorge themselves on meat” (Proverbs 23:20 NIV) and “Let us purify ourselves from everything that contaminates body and spirit, perfecting holiness out of reverence for God” (2 Corinthians 7:1 NIV). They are asked to reflect on the behaviors in their own lives—such as eating junk food or not exercising—that are inconsistent with their professed faith and values. When they identify a disconnect between their faith and their actions, they are encouraged to create an action plan for changing that behavior. Believing that losing weight and exercising is what good Christians do is powerful social proof—far more motivating than getting a stern warning from a doctor after getting bad results on a cholesterol test.
Mark Ansel, the psychologist who developed this approach, argues that religious communities should take on more responsibility for supporting behavior change. Places of worship could offer fitness classes and nutrition talks alongside religious services, and social events should serve healthier food. He points out that for this approach to work, religious leaders will have to be good role models. Before they start preaching morning walks, they need to get in shape themselves—and just like they wouldn’t be caught in a brothel, they’ll need to think twice about stepping into the local McDonald’s. After all, social proof requires proof.
