Intermittent Fasting Shows No Clear Advantage Over Traditional Diets for Weight Loss

A comprehensive new Cochrane review of 22 studies involving nearly 2,000 participants over six months to one year has found that intermittent fasting may offer little to no significant benefit over standard dietary advice for weight loss in people with overweight or obesity. When compared to regular, calorie-restricted diet plans, intermittent fasting—which includes methods like time-restricted eating or alternate-day fasting—resulted in only a minimal difference in weight loss (an average of 0.33% greater loss) and showed no meaningful impact on quality of life or adverse events, though the evidence for the latter two outcomes is uncertain. The review also found that while fasting was somewhat more effective than doing nothing at all, it did not lead to clinically meaningful changes in most health outcomes. The authors conclude that physicians and patients should base the decision to try intermittent fasting on individual practicality and sustainability, rather than an expectation of superior results, noting that more long-term research is needed to understand its effects beyond 12 months.
