Obesity (body mass index of 30 or more) is a global health problem that significantly increases the risk of developing a range of chronic disorders such as diabetes, cardiovascular diseases, and musculoskeletal disorders.
Consequently, being overweight can shorten life expectancy by ≤8 years and reduce the duration of healthy life by ≤19 years. More than 2.8 million people die each year due to conditions related to obesity.
Despite the known link between obesity and developing life-threatening conditions, the number of obese individuals worldwide has tripled over the last four decades. More than two-thirds of US adults are now overweight or obese.
