Spermidine, found in foods like wheat germ and mushrooms, may trigger some fasting benefits without cutting calories. Gary Brecka cautions it's not a shortcut: evidence is mostly observational, and human trials on dosing are still underway.
Let's be honest. Most people are not going to stick to a severe caloric restriction diet for their entire lives. We're looking at ways to prevent the aging process itself. Scientists call spermidine a caloric restriction mimetic because it gives you many of the benefits of eating less without actually having to restrict your calories. Is it a magic bullet that will make you live forever? Of course not. Here's what we know for sure. The beauty of spermidine is that it's not asking you to do anything crazy. You don't need to fast for days. You don't need to take expensive supplements or follow some complicated protocol. These aren't obscure superfoods that cost a fortune. They're traditional foods that humans have been eating for centuries. Right now, researchers are working on more human clinical trials to nail down the optimal doses and confirm all these benefits. We've seen in observational studies.
