The Claim

In overweight and obese adults, normal intermittent fasting (typically two days per week of calorie restriction) does not result in significantly greater body weight reduction compared to continuous calorie restriction, with a standardized mean difference of -0.10 (95% CI: -0.26 to 0.05), based on data from nine randomized controlled trials.

In plain English

If you're trying to lose weight and are overweight or obese, cutting calories just two days a week doesn’t work much better than cutting them every day — the difference is pretty small.

What the research says

1 study
  1. Study: Intermittent Fasting versus Continuous Calorie Restriction: Which Is Better for Weight Loss?

    The study looked at the same type of fasting and dieting as the claim, but found that fasting helped people lose more weight than cutting calories every day, which goes against the claim that both work about the same.
