The Claim
Intermittent fasting and caloric restriction are equally effective in improving insulin sensitivity in adults with overweight or obesity, as both interventions lead to significant reductions in fasting insulin, HOMA-IR, and glucose AUC over intervention periods ranging from 1.25 to 12 months, based on findings from multiple randomized controlled trials involving prediabetic men, healthy non-obese individuals, and individuals with metabolic syndrome.
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.
Going without food on certain days works just as well as eating fewer calories every day to help your body respond better to insulin, especially if you're overweight or have early signs of diabetes.

Intermittent fasting and caloric restriction are equally effective at improving insulin sensitivity in adults with overweight or obesity, with both interventions producing significant reductions in fasting insulin, HOMA-IR, and glucose AUC over intervention periods of 1.25 to 12 months, as shown in multiple randomized trials involving prediabetic men, healthy non-obese individuals, and those with metabolic syndrome.
What the research says
1 studyThe review says fasting and cutting calories work about the same for heart‑related health, but it doesn't give the exact blood‑sugar numbers the claim talks about.
