Potato chips top the list of foods that cause weight gain, followed by potatoes, sugar-sweetened beverages, unprocessed red meats, and processed meats. Foods that lead to weight loss include yogurt, nuts, fruits, whole grains, and vegetables.
These findings aren't shocking, but they do emphasize that when it comes to long-term health, focusing on the quality of one's diet is more important than just keeping track of calories or fat. As the study's co-author states, "The idea that there are no 'good' or 'bad' foods is a myth that needs to be debunked."
