Almost 40% of U.S. adults are considered not just overweight, but obese. Another significant number of Americans are overweight. Obesity puts you at increased risk for type 2 diabetes mellitus, cardiovascular disease (or heart attack and stroke), premature death, and increased risk for some cancers. Even a 5-10% decrease in body weight has been shown to reduce complications related to obesity and improve quality of life.
