Obesity: 10 keys to sustained weight loss over time

The latest research presented at the XVII Jornadas Argentinas de Nutrición and V Jornadas Argentinas de Obesidad highlights the challenges of maintaining weight loss over time. Experts emphasize that sustaining a reduced weight is more complex than achieving initial goals due to metabolic and hormonal mechanisms that encourage the body to regain lost weight. This phenomenon was one of the key topics discussed during the conferences. According to scientific evidence, obesity is a chronic and multifactorial disease. When individuals lose weight, hormonal signals related to appetite change, and energy expenditure alters, effects that can last up to a year after weight reduction, according to studies published in The New England Journal of Medicine. Dr. Virginia Busnelli, president of the Argentine Society of Nutrition (SAN), noted that maintaining results does not rely solely on discipline but rather on understanding the biology of the condition. Dr. Marianela Ackermann, vice-president of the SAN, outlined ten essential guidelines to help sustain weight loss. These recommendations include recognizing that reaching a target weight does not mean ending treatment. Continuous medical supervision allows early detection of changes in appetite or behavior, enabling timely adjustments to the treatment plan. Building a sustainable diet, rather than following restrictive meal plans, is another key point. It involves incorporating flexible eating patterns with lean meats, fruits, vegetables, and dairy products that ensure satiety and nutrition in everyday life. Avoiding overly strict diets helps maintain long-term adherence to healthy habits. Addressing "food noise", constant intrusive thoughts about food, is crucial. This psychological factor requires professional evaluation and should not be blamed on a lack of self-control. Managing these thoughts effectively contributes to better dietary choices and emotional well-being. Maintaining physical activity and preserving muscle mass is vital. Combining aerobic exercise with strength training supports muscle function and cardiovascular health. Regular movement plays a role in preventing weight regain and improving overall fitness levels. Monitoring progress is recommended, but not through daily weighing. Periodic tracking aims to identify gradual trends over time instead of reacting to daily fluctuations. This approach encourages a more realistic and consistent view of progress. Sleep quality is considered part of the treatment process. Poor sleep disrupts hormones that regulate appetite and negatively affects daily food choices. Ensuring adequate rest supports healthier eating behaviors and overall wellness. Identifying stress and personal barriers is necessary for tailored therapeutic strategies. Work-related, personal, or environmental factors require personalized approaches to address specific challenges faced by each individual. Having a plan for difficult moments and acting promptly is advised. A partial increase in weight does not indicate failure but serves as a clinical signal to consult early. Prompt intervention can prevent relapse and support continued progress. Creating an environment that supports healthy habits, rather than relying solely on willpower, is emphasized. Organizing grocery shopping, setting regular meal times, and receiving family support contribute to the sustainability of positive lifestyle changes. If a medical treatment is indicated, it should not be discontinued simply because the desired weight has been achieved. The continuation of pharmacotherapy must be evaluated individually by professionals to avoid biological recurrence of the condition.
