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
Obesity, as defined by the World Health Organization (WHO) as an abnormal or excessive accumulation of fat that presents a risk to health, has reached pandemic levels. Since 1980, its prevalence has doubled, affecting approximately one-third of the world's population. This increase spans all ages and both sexes, regardless of geographic location, ethnic origin, or socioeconomic level, though it is more prevalent in older individuals and women.
Obesity is a complex multifactorial disease primarily caused by an imbalance between energy intake and expenditure. Genetic, epigenetic, social, and microenvironmental factors contribute to its development. The main drivers of this pandemic are changes in the global food system, increased sedentary behavior, and reduced physical activity.
Complications and comorbidities associated with obesity include nearly all non-communicable diseases, such as type II diabetes, myocardial infarction, various types of cancer, immune system problems, and increased mortality in adulthood. Obesity also poses a significant economic cost, with 32% higher healthcare expenses compared to people of normal weight, divided into 31.8% direct costs and 68.2% indirect costs.
Currently, the most effective and cost-efficient long-term treatment for weight loss in people with obesity and comorbidities, or severe obesity, is bariatric surgery. Bariatric surgery is cost-effective, especially in the long term, helping to reduce body weight in the first years after the intervention (56.7% for gastric bypass and 45.9% for gastric balloon in the first ten years), improving metabolic control, and reducing obesity-related comorbidities.
However, individuals undergoing gastric bypass or gastric balloon surgery tend to regain weight in the long term. At least one in six operated individuals regain weight, and by 24 months post-surgery, up to 50% of patients regain weight. Factors such as genetics, anatomy, gastrointestinal hormones, adherence to a balanced diet, and healthy behaviors (reducing sedentary behavior and increasing physical activity) influence weight regain after bariatric surgery.
Sedentary behavior and physical activity are crucial for maintaining weight loss post-bariatric surgery. Physical activity post-surgery increases weight loss by 4%, and when performed before the intervention, improves weight loss at 12 months follow-up. However, the predisposition to obesity and weight regain post-surgery is influenced by factors such as lack of professional support, accessibility to sports facilities, and low socioeconomic status, making it difficult to improve physical activity levels and reduce sedentary behavior with simple health advice.
Despite this knowledge, hospital interventions before and after bariatric surgery focus on improving diet and only offer advice on physical activity, never physical activity and health behavior change interventions. Although diet is crucial and these interventions are often sufficient, physical activity and reducing sedentary behavior require supervised interventions of more than six months to achieve long-term behavior changes.
For these reasons, it is important to study through randomized clinical trials, with long-term follow-up, the effects of physical activity and reducing sedentary behavior on weight control, metabolic outcomes, and the quality of life, both mental and physical, of people with obesity who are going to undergo or have undergone bariatric surgery.
The B-FIT (Bariatric surgery and FITness) project aims to create a new referral and intervention model, from Hospital Sant Joan de Déu (Fundación Althaia) to the University of Vic-Central University of Catalonia, for physical activity and reducing sedentary behavior in people with obesity, both before and after bariatric surgery. This model aims to prevent post-surgery weight regain and promote healthy habits through behavior change techniques and supervised physical activity.

Exclusion Criteria:
Participants in this group will receive the usual hospital care, which includes psychology visits, nutritional advice, and a physical activity protocol plan. In addition, participants will be referral form the Hospital to the Unviersity to undertake supervised physical activity sessions and health behavior change techniques aimed at reducing sedentary behavior and improving quality of life. This intervention will start 8 months before surgery and continue for 12 months post-surgery, with regular monitoring and support to sustain life-changing behaviors.
Behavioral: Behavioral to reduce sedentary behvaior · Behavioral: Physical activity · Procedure: Bariatric Surgery
Participants in this group will receive the usual hospital care, including psychology visits, nutritional advice, and a physical activity protocol plan. Additionally, participants in this group will be referral from the Hospital to the Unviersity to begin supervised physical activity sessions and health behavior change techniques 12 months post-surgery, designed to reduce sedentary behavior and improve quality of life, with continuous professional support throughout the intervention period.
Behavioral: Behavioral to reduce sedentary behvaior · Behavioral: Physical activity · Procedure: Bariatric Surgery
Participants in this group will receive the usual hospital care, which includes psychology visits, nutritional advice, and a physical activity protocol plan provided on a sheet. There will be no additional supervised physical activity sessions or health behavior change techniques beyond the standard care currently provided by the hospital.
Procedure: Bariatric Surgery
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.
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.
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.
