The Claim

In adults with overweight and obesity, isocaloric intermittent fasting regimens result in weight loss and improvements in metabolic risk factors for noncommunicable chronic diseases that are generally comparable to those achieved through daily caloric restriction, indicating no major advantage of one dietary approach over the other when total energy intake is equated.

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Cause and effect
1 study reviewed
In plain English

If you're an adult with extra weight, cutting calories by either fasting some days or eating less every day leads to similar weight loss and health improvements — neither method works much better than the other if you eat the same total amount of food.

See the scientific wording

In adults with overweight and obesity, isocaloric intermittent fasting regimens produce weight loss and improvements in metabolic risk factors for noncommunicable chronic diseases that are generally comparable to those achieved with daily caloric restriction, suggesting no major advantage of one approach over the other when total energy intake is matched.

What the research says

1 study
  1. Study: The Effects of Isocaloric Intermittent Fasting vs. Daily Caloric Restriction on Weight loss and Metabolic Risk Factors for Non-communicable Chronic Diseases: A Systematic Review of Randomized Controlled or Comparative Trials.

    The study looked at intermittent fasting and daily dieting with the same calorie levels and found both help with weight loss and health risks about the same.
