About this trial

Obesity, defined by the WHO as an abnormal or excessive accumulation of fat that presents a risk to health, has reached pandemic levels, affecting approximately one-third of the world's population. This increase spans all ages, sexes, and socioeconomic levels, though it is more prevalent in older individuals and women.

Obesity is caused by an imbalance between energy intake and expenditure, influenced by genetic, epigenetic, social, and environmental factors. Key drivers are changes in the global food system, increased sedentary behavior, and reduced physical activity.

Complications include type II diabetes, myocardial infarction, various cancers, immune system problems, and increased mortality. Obesity also results in significant economic costs, with healthcare expenses 32% higher than for people of normal weight.

Bariatric surgery is the most effective long-term treatment for severe obesity, helping reduce body weight significantly in the first years post-surgery and improving metabolic control. However, individuals often regain weight in the long term. Factors influencing this include genetics, gastrointestinal hormones, adherence to diet, and healthy behaviors like physical activity.

Sedentary behavior and physical activity are crucial for maintaining weight loss post-surgery. Physical activity increases weight loss by 4% and improves outcomes when performed before surgery. However, lack of professional support, accessibility to sports facilities, and low socioeconomic status make it difficult to sustain these behaviors with simple advice alone.

Despite this, hospital interventions often focus solely on diet, offering only advice on physical activity. Effective interventions require supervised programs of more than six months to achieve long-term behavior changes.

The B-FIT (Bariatric surgery and FITness) project aims to create a new referral and intervention model for physical activity and reducing sedentary behavior in people with obesity before and after bariatric surgery. This model seeks to prevent post-surgery weight regain and promote healthy

Treatments tested in this trial

  • Behavioral to reduce sedentary behvaior

    Behavioral

    This intervention will also utilize a geographical time app to raise awareness about participants' sedentary lifestyles, helping them identify opportunities to incorporate more movement into their daily routines. Furthermore, the program will implement the Wheel of Change behavior technique, which serves as a structured approach to facilitate lasting changes in health behaviors, empowering participants to take control of their physical activity levels and overall well-being.

  • Physical activity

    Behavioral

    This intervention will be conducted with two weekly days of supervised and structured physical activity sessions, held at the university's facilities, providing participants with expert guidance and a supportive environment to enhance their physical fitness and overall health.

  • Bariatric Surgery

    Procedure/Surgery

    In this intervention, bariatric surgery will be performed, accompanied by the usual hospital care, which includes comprehensive nutritional and physical activity advice. This standard care ensures that participants receive essential guidance and support for their dietary and exercise routines, complementing the surgical intervention.
