An Exploratory Pilot Study to Assess the Effect of Intermittent Fasting on Anthropometric Parameters, Biochemical Factors, and Pro-Inflammatory Biomarkers

Introduction: Fasting denotes abstinence from food or drink or both for well-being, ritualistic, and spiritual purposes. This study was conducted to explore the effect of Navratras fasting on anthropometric parameters, biochemical factors, and pro-inflammatory biomarkers. Materials and Methods: This study was a short-term longitudinal follow-up study conducted during Navratras (Oct 2020) in a residential medical college campus in western Maharashtra. Assessment of the participants based on anthropometry, biochemical, and pro-inflammatory markers was done at three-time points 7 days before the start of intermittent fasting (T1) (before the start of Navratras), at the end of intermittent fasting (the last day of the festival) (T2) (during Navratras), and 1 week after completion of intermittent fasting (T3) (after the end of Navratras). Results: A total of 50 subjects participated in the study, and the mean age of study participants was 33.6 ± 10 years. There was a significant reduction in body weight (P = 0.001), waist circumference (P = 0.001), and hip circumference (P ≤ 0.05) during the intermittent fasting period (T2). Significantly lower levels of total cholesterol (P < 0.01) and low density lipoprotein (LDL) (P < 0.01) were observed in the T2 and T3 time points of sampling. However, a significant increase in TNF-alpha, IL-1, IL-6, and IL-8 levels was observed during the T2 phase (P < 0.001). Conclusion: The current exploratory study evaluating the importance of intermittent fasting during Navratras showed a significant reduction in certain anthropometric as well as biochemical parameters. It is recommended that intermittent fasting may be considered by individuals who are overweight and need to improve overall health. However, it is important that like any other weight-loss program, intermittent fasting should also be undertaken under medical supervision.
