Obesity is treatable. Generally, the treatment of obesity mainly includes several aspects: First, dietary intervention; second, increased physical activity; third, correcting bad behavioral habits; some cases may require medication and surgery. Dietary treatment mainly involves reducing calorie intake and recommending a low-sugar diet. Physical exercise generally requires three to five days of activity per week, with 30-40 minutes each day being appropriate. It also includes correcting some poor dietary habits and enhancing self-monitoring, including records of food intake and daily physical activity. Medication treatment is an option for individuals with a body mass index (BMI) of 30 or higher, or a BMI of 27 or higher who also have obesity-related comorbidities. This treatment can be combined with exercise and dietary behavioral corrections. Furthermore, for those with a BMI of 40 or higher, or a BMI between 35-39.9 with one or more severe obesity-related complications such as hypertension, heart failure, type 2 diabetes, or sleep apnea, surgical treatment may be considered.
