What the research says

3 studies
  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 number of calories and found people lost about the same amount of weight, which supports the idea that both methods work similarly when food intake is matched.
