چکیده

Background: Although many studies have been conducted to compare the effect of adherence to a low-carbohydrate diet (LCD) with a low-fat diet (LFD) on anthropometric indices and body fat percentage, there is still no definite conclusion in this regard. Therefore, the present study aims to summarize results of studies comparing a LFD and a LCD on weight loss. Methods: A systematic search of databases including PubMed, Scopus, and Cochran Library was performed up to November ۲۰۲۰. All randomized controlled trials (RCTs) comparing the effect of adherence to a LCD with a LFD on anthropometric indices and body fat percentage were included. Search results were limited to English-language publications. Sixty-three RCTs, including ۷۶۶۰ participants, were selected for the present study. Results: Pooled analysis indicated that adherence to LCD was significantly associated with a greater reduction in BMI (SMD = - ۰.۰۷, ۹۵% CI: -۰.۱۴,-۰.۰۰۱; P = ۰.۰۴), weight (kg) (SMD = - ۰.۲۲, ۹۵% CI: - ۰.۳۱, - ۰.۱۲; P ≤ ۰.۰۰۱), and percentage of body fat mass (SMD = - ۰.۲۸, ۹۵% CI: -۰.۴۸, - ۰.۰۸; P = ۰.۰۰۶) compared to LFD. However, no significant difference in changes of kilogram of body fat mass and waist circumference was observed between the two diet programs. Conclusion: Overall, adhering to LCD was more effective than LFD in losing weight and body fat percentage.
