Weight Loss Interventions in Polycystic Ovary Syndrome: Key Approaches
Lifestyle Interventions: Diet, Exercise, and Behavioral Strategies
Lifestyle interventions, which combine dietary changes, physical activity, and behavioral support, are widely recognized as the first-line treatment for weight management in women with polycystic ovary syndrome (PCOS) 26710. These interventions are effective in achieving modest weight loss (5–10% of initial body weight), which is associated with improvements in central adiposity, insulin resistance, hyperandrogenism, and cardiovascular risk factors 26. Evidence shows that there is no single superior dietary approach; rather, interventions should be tailored to individual preferences and nutritional needs, ideally with professional guidance 29.
Effectiveness of Specific Non-Pharmacological Interventions
Recent analyses highlight that certain non-pharmacological interventions, such as combining nutritional supplements with a low-calorie diet, Taichi, and continuous aerobic exercise, offer the greatest clinical benefits for weight loss, body mass index (BMI), and waist circumference in women with PCOS . Notably, Taichi was found to be particularly effective, challenging the common belief that only high-intensity exercise is beneficial for weight loss in this population .
Behavioral Interventions and Psychological Support
Behavioral interventions, including goal setting, self-monitoring, cognitive restructuring, and relapse prevention, play a crucial role in supporting weight loss and maintenance in women with PCOS 57. These strategies not only help reduce weight, BMI, and waist circumference but also improve depression and quality of life related to weight 57. However, the long-term effects of behavioral interventions remain unclear due to the short duration and varying quality of available studies 54.
Impact on PCOS Symptoms and Biomarkers
Weight loss interventions are associated with significant improvements in insulin resistance (HOMA-IR), free androgen index (FAI), and menstrual frequency in women with PCOS 36. However, there is limited evidence for improvements in hirsutism, overall quality of life, or other sex hormones, possibly due to insufficient study power 356. Lifestyle interventions may also reduce triglyceride levels and improve some metabolic parameters, but effects on blood pressure, cholesterol, and glucose tolerance are less clear 56.
Long-Term and Adherence Challenges
Long-term, non-surgical weight loss interventions for PCOS are less studied, and existing research shows that including a lifestyle component improves outcomes, though clear protocols and strategies are needed for better compliance and validity . High attrition rates are common, with depressive symptoms and low appointment attendance linked to dropout, while higher attendance is associated with greater weight loss success . Addressing psychological barriers and providing ongoing support are important for improving adherence and outcomes 7810.
Conclusion
Weight loss interventions, especially those combining dietary, exercise, and behavioral strategies, are effective in improving weight and some clinical features of PCOS. Tailored, multidisciplinary approaches that include psychological support and address individual barriers are most successful. While modest weight loss leads to meaningful health improvements, further research is needed to optimize intervention components and support long-term adherence in women with PCOS 1234+6 MORE.
