More than 50% of US adults are overweight, with a body mass index of more than 25 kg/m2 (calculated as weight in kilograms divided by the square of height in meters).1 Even more concerning, the percentage of Americans who are obese (body mass index ≥30 kg/m2) has increased by more than 50% in the past 20 years, and the number of overweight children has doubled.2 Most overweight individuals can successfully lose some of the weight, but the majority regain that weight within 5 years.3
