London, UK – A new study published in BMC Medicine has found that intermittent fasting (IF) can be an effective alternative to traditional continuous calorie restriction diets for improving metabolic health.
Researchers analyzed data from over 9,800 participants across 153 studies, comparing three popular IF regimens – time-restricted eating, alternate-day fasting, and the 5:2 diet – with continuous energy restriction and usual diets.
The study, which employed a network meta-analysis to combine direct and indirect evidence, found that all IF regimens were significantly more effective than usual diets in reducing body weight and improving various metabolic factors like blood pressure, blood sugar levels, and cholesterol.
“Our findings suggest that intermittent fasting can be a valuable tool for improving metabolic health,” said lead researcher Yu-En Chen.
The analysis revealed that alternate-day fasting consistently emerged as the most effective IF strategy, demonstrating superior results in the majority of comparisons.
“While all IF regimens showed promise, alternate-day fasting appeared to offer the most substantial benefits across a range of metabolic outcomes,” Chen added.
The study emphasizes that IF can be a viable and effective approach for individuals seeking to improve their metabolic health. However, it is crucial to consult with a healthcare professional or registered dietitian before starting any new diet, including intermittent fasting, to ensure it is safe and appropriate for individual needs and health conditions.
