from healthfinder.gov it was reported that the study involved 2,433 people who were ages 20 to 32 in the mid-80's. Most were women and 41 percent were black. The study author Michael J. Feinstein, a medical student from Northwestern University in Chicago, said, "It highlights a particular group that appears to be a greater risk of becoming obese and remaining obese. It's a group that may benefit from targeted anti-obesity interventions and from obesity prevention programs". He also stated that the finding is surprising, especially considering that religious people tend to be in better health than others.
There are factors that might play a role in religious people being obese. One of them is diet. Some of the people in the study ate fried foods and loaded up on desserts after the service.
Another factor is physical inactivity. People sat for extended periods of time and when the service ended they tended to eat foods that weren't healthy. Even though the people were obese, they were still in good health and that may be due to the fact that fewer of them are smokers.
