Management of obesity

From 1975-2016, the number of people with obesity in Europe increased fivefold and the overall trend is still increasing. Obesity is the result of an imbalance between energy expenditure and caloric intake. Although the importance of genetic determinants for the variance of body mass index (BMI) is about 60-70%, overeating, lack of exercise, and psychosocial stress are influenceable risk factors. For example, during the Corona pandemic, nearly 40% of Germans gained an average of 5.6 kg, and people with obesity gained as much as 7.2 kg. To reduce obesity-associated comorbidities, a permanent reduction in body weight of (at least) 5-10% is recommended. A significant reduction of cardiovascular endpoints can be achieved with a weight reduction of more than 10% of the initial weight. Therapeutic measures in the context of an escalating stepwise approach should include strategies for targeted weight reduction and long-term weight maintenance.
