After 16 weeks, study participants following the vegan diet lost an average of 14 pounds. One researcher described the team's findings as "groundbreaking." 

The study's authors explored data from more than 37,000 adults. 

The study, published in Heart, examined how even minor dietary changes can affect a person's health. 

In addition, 49% of U.S. adults said the fear of unexpected bills keeps them from seeking care.
