Many physicians lack sufficient knowledge to prescribe or follow up on intermittent fasting for patients.

“But the second reason was that many physicians are being approached by patients, asking the physicians about intermittent fasting. And in some cases, maybe many cases, the physicians really don't know much about it. They don't know that there's actually quite a bit of science behind it, both basic and clinical. And from a practical standpoint, they don't know how to prescribe intermittent fasting to a patient, and then follow up with them to try to help them switch their eating pattern.”
