The Impact of Intermittent Fasting on Metabolic Health and Chronic Disease Prevention: A Comprehensive Review

Abstract : Intermittent fasting has gained attention as a dietary approach focusing on the timing of eating rather than the specific foods being consumed. Unlike the traditional calorie restriction, intermittent fasting involves alternating periods of fasting and eating. Several prevalent forms of IF exist, each with unique fasting durations and eating windows. For instance, the 16/8 method restricts food intake to an 8-hour window each day, followed by 16 hours of fasting. The 5:2 diet involves eating regular meals for five days a week and significantly reducing calorie intake to 500-600 calories on the remaining two non-consecutive days. Another popular method, Eat-Stop-Eat, includes one or two 24-hour fasts per week without calorie restriction on non-fasting days.The rising interest in IF is due to its potential health benefits, such as weight loss, chronic disease prevention, and improved metabolic health. IF may reduce the risk of obesity, diabetes, cardiovascular disease, and certain cancers. The increasing interest in IF is largely due to its potential health benefits, including the prevention of multiple chronic diseases, weight reduction, and improvements in metabolic health markers. A growing body of scientific evidence suggests that IF may positively impact metabolic health, potentially reducing the risk of obesity, diabetes, cardiovascular disease, and certain types of cancer. Intermittent fasting can enhance weight management and health improvement, but further research is needed to understand its long-term effects on people, optimal protocols, and potential risks. This will help guide informed decisions on the safe way and effective use.
