Objective. This study was aimed at evaluating the effect of intermittent fasting of Ramadan on resting energy expenditure (REE), body composition, and nutritional status. Methods. The study was conducted on a total of 27 adults (16 females, 11 males) who were fasting (18 h) in the Ramadan month (May 6-June 3) of 2019. REE was measured using the indirect calorimeter. Dietary energy and nutrient intakes were evaluated by 3-day food records in baseline and post-Ramadan. Body composition and some metabolic parameters were analyzed simultaneously with REE measurements. All measurements were performed two times at baseline, and post-Ramadan. Results. Body weight (-2.9% vs. -1.4%), body mass index (BMI) (-3.1% vs. -2.1%), fat-free mass (-2.7% vs. -1.4%), and hydration status were decreased in both males and females after the Ramadan fasting (p < 0.05). REEs (kcal/d) of the participants were 1708.1 +/- 262.50 kcal/d and 1596.5 +/- 302.27 kcal/d at baseline and post-Ramadan, respectively (6.5%) (p < 0.05).)is decrease in REE (kcal/d) in females was greater than that in males (-8.1% vs. -4.6%). However, no statistically significant difference was found in sleep duration (h), physical activity levels, dietary energy and nutrient intakes, and blood pressures (mm Hg) of both genders compared to baseline (p > 0.05). Conclusion. Intermittent circadian fasting may lead to a decreased energy expenditure and a change in fat-free mass in healthy individuals, and this effect is interpreted as gender-dependent.
