But what's on that podcast could make the difference between losing a modest amount of weight and losing next to none, according to a new study out of the University of North Carolina, Chapel Hill. Researchers used two types of podcasts to see which was more effective at helping 78 overweight and obese men and women shed pounds over 12 weeks.
After three months, the study group lost an average 6.4 pounds and one point in their body mass index. The control group lost an average of 0.7 pounds and lost 0.1 BMI point. The study appears online in the American Journal of Preventive Medicine.
