Brief Summary

Obesity is a disease caused by many factors, such as lifestyle, eating habits, lack of physical activity, hormonal and genetic influences. These different factors make treatment planning difficult. Common treatments include changes in diet and lifestyle, medications, endoscopic methods (like balloon or botox), and surgery. No matter which method is used, the main goal is to help patients lose weight by creating a negative energy balance. To keep the weight off, patients need to maintain a balanced lifestyle in the long term. However, many treatments are not successful over time. One important part of long-term success is helping patients change their lifestyle and eating habits. A person's cognitive function may affect how they understand and follow these changes. Some studies show that a high body mass index (BMI) is linked to problems with thinking and memory. While weight loss may help improve brain function, the investigators don't yet know how early cognitive differences affect treatment results. At the obesity center in our hospital, morbidly obese patients receive support from a team of doctors, dietitians, psychologists, and physiotherapists. For at least three months, they attend individual and group sessions to help change their lifestyle and eating habits. This study aims to see how patients' cognitive function affects how much weight they lose by the end of the program.
