Study: Intermittent Fasting No Better Than Regular Diets
A Cochrane review of 22 trials with nearly 2,000 adults found intermittent fasting offers little to no advantage over calorie restriction or no intervention for weight loss.
- Published Monday, the Cochrane analysis found intermittent fasting may result in little to no difference in weight loss compared with regular advice or doing nothing.
- Surging public interest in IF has grown in recent years, fueled by social media and lifestyle influencers, prompting researchers to assess it amid obesity as a major public‑health challenge.
- The review pooled 22 randomised controlled trials involving 1,995 adults aged 18–80 across North America, Europe, China, Australia and South America, but most trials lasted up to 12 months with inconsistent side-effect reporting.

- To fill evidence gaps, the authors recommend future trials with longer follow-up and better reporting in low- and middle-income countries, including participant satisfaction and diabetes status, while experts urged that exercise and weight-loss medications support population-level obesity strategies.
