People who do not own a car and live in areas with a high concentration of fast food restaurants in close proximity are more likely to become obese according, to a new study.

The study examined adults living in 63 different neighborhoods within Los Angeles County, and it found that on average, those who lived in areas with five or more fast food eateries per square mile were 12 pounds heavier than those from areas with lower concentrations.

The results seemed contradictory to the assumption that those who own cars live less active lifestyles, but researchers noted that the lack of transportation and healthy food choices is difficult to adjust for, particularly among low-income individuals.

"Since our study showed that total restaurant density was associated with weight gain in all individuals, not just those who did not own cars, we also need to encourage people to pay more attention to their food environment," said Dr Sanae Inagami, the study’s lead author.

Those who find themselves in this kind of situation may want to turn to exercise to offset their high caloric intake. Riding a bike to purchase groceries is one way to find healthy food and work off excess weight. Supplements containing omega-3 fatty acids or Coenzyme Q10 may also help by reducing cholesterol levels.
