00:00What if you stopped eating for three days? We've been programmed to nourish our body to heal,
00:06right? Before you buy into that, let me just turn your universe upside down for a minute
00:11and just hear me out. There's one single problem behind all chronic disease, including cancer,
00:17and that is insulin resistance. You don't get insulin resistance by not eating. You get insulin
00:23resistance by eating too frequently. Too much insulin that leads to insulin resistance blocks
00:27the cells from getting any fuel. When we overnourish our body by eating too frequently,
00:33we create this insulin resistance situation. Every single person that has a slow metabolism,
00:39they went on many diets. The diets that destroy the metabolism the most were you're going to be
00:44eating five to six small meals a day. You get a snack before a meal so you don't overeat because
00:50this crazy idea that too many calories equal weight gain. Actually, it's more of the frequency of meals
00:57that creates insulin resistance, that creates chronic disease that will make you very, very
01:01overweight. But when we start to not eat so frequently and we start to do intermittent fasting,
01:07things start turning around. Let's get into the benefits of intermittent fasting and prolonged
01:12fasting. If you were to eat right now, your insulin will go up. And because insulin is going to go up,
01:18that higher insulin is going to prevent a lot of good things that are going to happen.
01:22Let's say you're going to fast for 18 hours and then you're going to eat at, let's say,
01:2712 o'clock noon and then you'll eat at six o'clock. So that's a six-hour eating window and then you have
01:32an 18-hour fasting window. A lot of benefits are going to happen if you do that. You're going to
01:36lose weight in your midsection. You're going to feel better mentally. Your mood will come up and your
01:43inflammation will start going down as well. When you do intermittent fasting, you're not really
01:47tapping in to all the stored sugar in your liver unless you start doing prolonged fasting. So let's
01:54say, for example, we're fasting from 24 hours one day to 48 hours two days. What's going to happen when
02:02you start doing this is you are going to take the benefits that I just mentioned and start to turn
02:07them way up. And one thing that's going to happen is you're going to deplete most of your glycogen in
02:13your liver. It's like a sponge with water. You're holding a lot of fluid. So in other words, you're
02:18going to lose a good amount of weight. And some people mistake that with actual fat loss. It's
02:23actually water loss. This is why when you start doing prolonged fasting, you'll lose the water first
02:27and then it plateaus. That doesn't mean it's not working. It just means that you dumped a lot of
02:31water with that stored sugar. When you start doing prolonged fasting one to two days, you are going to be
02:37burning mostly ketones. 87% of your fuel is ketones. You're not feeding your microbes, but they're
02:46thriving. Your hormones, especially human growth hormone, will start to go straight up and vertical. And
02:53then you can increase that growth hormone when you do fasting by 2000%. So you're not going to be losing
02:58muscle, but it actually will help the growth of muscle, but it'll also help the burning of fat. It's one of the
03:05most powerful fat burning hormones. You're going to notice the benefits on your brain because you have
03:10a higher level of ketones feeding the neurons. Autophagy is going to kick in. Autophagy is where
03:15you're taking the junk and you're turning it into new cells. So think of the self-cleaning oven. And it's
03:21a magical process where you have to get certain resources and fuel from somewhere. And so your body
03:27will definitely tap into your fat, but it will also tap into stuff that's not really needed in the body.
03:32And it starts to convert that into very valuable resources that your body needs. You see, you cannot
03:39go into autophagy when you nourish your body, when you're eating. Even when you take supplements,
03:44you're not going to significantly increase autophagy. It's only when you don't eat. Prolonged fasting
03:50allows you to prune your brain and it allows you to build new brain cells. You only do that to a
03:56certain degree, but with intermittent fasting, but a lot more when you do prolonged fasting.
03:59Insulin powerfully shuts down autophagy. Insulin shuts down fat burning. It shuts down the
04:05regrowing of the brain cells. And with that, what happens when you fast longer? Let's say we're
04:11going to go to 72 hours. Autophagy starts cleaning up intracellular pathogens. I'm talking about viruses.
04:19I'm talking about Epstein-Barr virus, even the herpes virus. Do you realize that there's no drug
04:24or even no supplement that can actually get rid of these latent viruses? The only way to get rid of
04:30them is through prolonged fasting. But not only that, when you start to go up into three days of
04:37fasting, you start to stimulate your immune system. The thing that actually protects you against cancer,
04:44autoimmune diseases. I mean, we're just told all these ideas that we have to nourish the body to get
04:49healthy. No, we actually don't. There's no doubt we need to nourish our body when we eat, but prolonged
04:54fasting transforms your health in so many different ways. You can do stem cell therapy. Some of the
05:01therapy is like $50,000. Well, guess what? You can get a stem cell therapy for free by just not eating.
05:09And also, I wanted to point out the inspiration for this video is from this book, Metabolic Freedom
05:14by Ben Azadi. I highly recommend you get it. I'll put a link down below in the description. Here's a couple
05:21last minute tips. When you're doing a water fast, whether it's intermittent fasting or prolonged fasting,
05:26you're not eating anything except you're drinking water. And so what breaks that fast is a certain amount
05:32of calories. So you wouldn't want to consume bone broth, for example. But you could do coffee. You could do tea.
05:39Why? Because it doesn't have any calories. It's when you add in certain things that you have a problem.
05:44Very important thing to note when you do intermittent fasting and prolonged fasting
05:47is to have enough sea salt. If you don't have enough sodium, you will feel tired. So when you're
05:54doing intermittent fasting, make sure you add a little more sea salt and probably like a teaspoon
05:59per day spread out and you can mix it with water. And I also recommend you do other electrolytes like
06:05potassium and magnesium because if you're deficient going into a prolonged fast, those deficiencies are
06:11exaggerated. I want to say one last important thing. You can really mess yourself up when you do
06:17refeeding after a three-day fast. Don't make the mistake that I made where I just started loading my
06:23body up with all this food. I got very sick. Maybe you started with some bone broth, wait a little bit,
06:28have a little bit of steamed vegetable, wait a little bit, have an egg. And then you let that settle for
06:34several hours and then have a slightly bigger meal. Maybe the following day, go back to your normal
06:40meals. But the point is the worst thing you could do is have a lot of carbohydrates or introducing food
06:46after a prolonged fast. That would be the worst mistake. So to get all the details on how to do
06:51prolonged fasting, you should watch this video right here.
