• Intermittent fasting fails to beat standard dieting for weight loss A major review finds intermittent fasting does not lead to greater weight loss than standard diet advice. • Intermittent fasting does not appear to help overweight or obese adults lose more weight than standard diet advice or even no structured program at all, according to a new Cochrane review. • The findings challenge the widespread belief that changing when you eat leads to better weight loss results than traditional approaches. • Obesity remains a major public health concern and is now one of the leading causes of death in high income countries. • The World Health Organization reports that adult obesity rates have more than tripled globally since 1975. • In 2022, about 2.5 billion adults were overweight, including 890 million who were living with obesity.
Article Summaries:
- A Cochrane review of 22 randomized trials involving 1,995 adults found that intermittent fasting does not lead to greater weight loss than standard diet advice or no structured plan. The studies, conducted across North America, Europe, China, Australia, and South America, examined various fasting protocols (alternate‑day, periodic, time‑restricted) over up to one year. Results showed no clinically meaningful difference in weight loss compared with conventional dietary guidance or no intervention. Researchers noted limited reporting of side effects and a small, uneven evidence base, underscoring the need for longer‑term, diverse studies before endorsing fasting as a superior weight‑loss strategy.
