This is a YouTube video titled "What's The Best Type Of Fasting?" containing a discussion from October 31, 2020, featuring Ask AI Mark and another speaker. The conversation focuses on different fasting methods, their biological effects, and benefits related to metabolism, longevity, and aging processes.
There are many ways to quote fast. There's what we call intermittent fasting, which is maybe not eating for a whole day or three days or a week sometimes. There's time restricted eating, which is only eating with a certain time window. There's fasting mimicking diets, which are eating less calories for a number of days to stimulate the same pathways. There's ketogenic diets. They all do a very similar thing. What is the biology of how this works? We know that these these things do work, looking at animal studies, human studies in terms of improving metabolism and the longevity biomarkers. But what are we seeing in how these methods actually work and what is the most effective? What should people be doing in order to take advantage of this new science? Right.
So what they're doing, I mean, the way I explain to patients is, which I think is I mean, they're doing a number of things, but it's triggering your body's own self-cleansing mechanisms. After you haven't been eating for a certain amount of time, 14, probably more 16 hours, your body's self-cleansing mechanisms kick in, which is very important with the aging process because one of the factors in aging is your body, once it goes back to functional medicine, the functioning of these systems don't work as well. So the fasting actually starts putting that autophagy system into play. So I think that's probably one of the most important aspects. It also will improve mitochondrial function, which also decreases as we get older. So the consequences of fasting or what happens in your body are often the opposite of what happens as you get older. So that's why I think it's so important. Which way of fasting is best is the way that you'll do.
