Obesity is having an excessive amount of body fat in relation to lean body mass that may impair health.
The primary cause is an energy imbalance between calories consumed and expended.
Treatment goals include to lose 5-10% of body weight or 0.5-1 kg (1-2 lb)/week for 6 months and regain of <3 kg in 2 years and sustained reduction of waist circumference of at least 4 cm.
Strategies are aiming for realistic goals and a multidisciplinary approach that is a combination of dietary change, physical activity and behavioral modification.
Implementation of a supervised exercise intervention for 12 weeks effectively improves body composition and functional walking ability in patients who have undergone bariatric surgery, and further improvements may be observed at the 24-week follow-up, according to a study.
A combination of aerobic and resistance exercise training during weight loss yields the greatest improvement in physical function and reduction of frailty, with relative preservation of lean mass, in older adults with obesity as compared with participation in either exercise training programme alone, according to a study.
