Restricting one's feeding window to 4-12 hours within a 24-hour cycle has shown benefits in mice and some human studies.

“So restricting your feeding to a particular window, every 24 hour cycle has clearly been shown now in mice and in humans to enhance liver health, which is wonderful.”

“because in mice we have done that experiment um after 12 hours they do get a lot of benefits not all but so this is 12 hours of 12 hours of feeding 12 hours of fasting yeah”

“What they saw was an improvement in liver enzymes, an improvement in insulin sensitivity, which is something that is good. It means that you can utilize the calories and the blood sugar that you happen to have. Being insulin insensitive is not good and is actually a form of diabetes. What Sachin's lab and subsequently other labs showed was that restricting one's feeding window to anywhere from 4 to 8 or even 12 hours during each 24-hour cycle was beneficial in mice. And some studies in humans have also shown that it can be beneficial for various health parameters.”
