Despite the widespread perception that fasting during Ramadan involves abstaining from food for long hours, recent studies reveal that weight may not necessarily decrease during this month. In fact, some individuals experience weight stability or even gain. This paradox has prompted researchers in recent years to reassess the genuine impact of Ramadan fasting on appetite, metabolism, and eating behavior patterns. A systematic review and data analysis published in Frontiers in Nutrition evaluated over 40 studies on weight changes during Ramadan. The findings suggest that any weight loss is often limited and temporary, occurring mostly during the initial weeks of fasting before typically returning to baseline shortly after the month concludes. Researchers attribute this phenomenon to what is known as "caloric compensation," where many fasting individuals tend to consume high-calorie meals after breaking their fast, effectively offsetting the calorie deficit created by hours of not eating. Additionally, disruptions to biological clock patterns further complicate weight management during Ramadan. This misalignment can lead to changes in hunger hormones, influencing appetite and satiety. Therefore, this period of fasting might not lead to the expected reductions in weight for many, as behavioral adaptations and biological responses conspire to maintain or even increase overall food intake.
