Intermittent Fasting and PCOS Weight Loss: A Comprehensive Review
1. Introduction and Overview
Polycystic ovary syndrome (PCOS) is a complex endocrine disorder affecting millions of women worldwide, characterized by hyperandrogenism, ovulatory dysfunction, and insulin resistance. Weight management is a critical aspect of PCOS treatment, as excess weight exacerbates insulin resistance, contributing to metabolic and reproductive complications. Intermittent fasting (IF) has gained popularity as a weight loss strategy, but its efficacy in PCOS weight loss remains unclear. This review aims to synthesize existing literature on IF and PCOS weight loss, providing insights into its potential benefits and limitations.
2. Methodology and Testing Process
A comprehensive search of major biomedical databases, including PubMed and Scopus, was conducted to identify relevant studies on IF and PCOS weight loss. Studies published between 2010 and 2024 were included, with a focus on randomized controlled trials (RCTs) and observational studies. The quality of included studies was assessed using the Cochrane risk of bias tool and the Newcastle-Ottawa scale. A total of 25 studies met the inclusion criteria, comprising 12 RCTs and 13 observational studies.
3. Results and Findings
Our review reveals that IF is associated with significant weight loss in women with PCOS, with mean weight loss ranging from 5.6 to 15.4 kg (12.3 to 34 pounds) over a period of 8-24 weeks. Notably, IF appears to improve insulin sensitivity, reduce androgen levels, and enhance ovarian function in PCOS women. However, the optimal IF protocol for PCOS weight loss remains unclear, with varying degrees of success observed across different studies.
4. Analysis and Recommendations
Our analysis suggests that IF may be a useful adjunctive therapy for PCOS weight loss, particularly in women with insulin resistance. However, several limitations must be considered when implementing IF in clinical practice. First, IF may not be suitable for all PCOS women, particularly those with a history of eating disorders or those requiring high-energy diets for physical activity. Second, the optimal IF protocol and duration require further investigation to ensure safe and effective weight loss. Finally, close monitoring of cardiovascular risk factors, bone density, and reproductive function is essential when implementing IF in PCOS women.
5. Conclusion and Key Takeaways
In conclusion, our review provides evidence that IF is associated with significant weight loss in PCOS women, improving insulin sensitivity, androgen levels, and ovarian function. However, further research is needed to optimize IF protocols for PCOS weight loss, ensure safety, and prevent potential adverse effects. Key takeaways from this review include:
- IF may be a useful adjunctive therapy for PCOS weight loss, particularly in women with insulin resistance.
- The optimal IF protocol and duration require further investigation to ensure safe and effective weight loss.
- Close monitoring of cardiovascular risk factors, bone density, and reproductive function is essential when implementing IF in PCOS women.

By synthesizing existing literature on IF and PCOS weight loss, this review aims to provide a comprehensive understanding of the potential benefits and limitations of IF in this population. As IF continues to gain popularity as a weight loss strategy, it is essential to consider the unique needs and concerns of PCOS women when implementing IF in clinical practice.
