Obesity has become a world-wide epidemic estimated to affect 1.7 billion individuals. Childhood obesity is also growing at alarming rates with one in every five children in the U.S. being either obese or overweight. It is estimated that 80% of obese children will go on to become obese adults.

Each year, an estimated 365,000 adults in the U.S. die of obesity related causes. At a BMI of greater than 30, individuals are at increased risk of premature death and development of serious obesity related diseases. Obesity is a risk factor for life-threatening diseases such as diabetes, heart disease, stroke, sleep apnea and certain cancers.
