How does intermittent fasting help with creating a better erection? Well, stay tuned. We're going to go over the reason why so what is intermittent fasting? Intermittent fasting mean that you don't eat for an extended period of time. Optimally most people recommend between 8 hours to 16 hours of no eating and you usually don't eat between 8pm to 8am and you can extend it to 16 hours to noon so you don't eat from 8pm to noon. Or you can make it 12 hours and eat at 8am but there are multiple benefit of intermittent fasting or long period of not eating. One of that benefit is that studies have shown that it does increase testosterone level. So when you are fasting you boost testosterone level which is good for a firmer erection. Now of course intermittent fasting alone, it's not going to give you a better erection. You have to combine it with lifestyle modifications and other factors like diet and exercise. But this is just one thing to consider in multiple modalities that you can do to improve your erection and therefore your sex life. The first thing is that intermittent fasting boosts testosterone, then it also improve blood flow. Now how does it improve blood flow? Because it is good for reducing inflammation. When you reduce inflammation, what it does is that it opens up the blood vessels more so you have more blood flow coming from your heart to the penis. Now I made it more simplified than it need to be, but essentially it's what it is. Inflammation. Imagine it as a fire that is burning the lining of your blood vessel and the lining your blood vessels like a pipe. And the inside lining of the pipe is inflamed or is leaking. So that's inflammation. But intermittent fasting can help repair the inflammation and the lining of the blood vessel. Number two, how does intermittent fasting help with blood flow is that studies have shown that it actually can even reduce blood pressure. It can even reduce blood sugar level and also your fasting lipid profile or your cholesterol level. So not only does it help you increase your testosterone, it's also helping you with increasing blood flow, decreasing your blood sugar, and also decreasing your blood pressure and your cholesterol. And also the number three benefit of intermittent fasting is that it actually improve your autonomic function. So what's autonomic function? Autonomic function is either sympathetic nervous system or a parasympathetic nervous system. And intermittent fasting has been shown to improve heart rate variability. Now what that means is that it enhances the activity of the vagus nerve or cranial nerve 10, which then lower heart rate. So when you lower the heart rate, you lower the stress and you improve heart rate variability, which then improve blood flow. So that's how intermittent fasting can help with increasing blood flow. Now the other benefit of intermittent fasting is that it also help with weight management as well. So it aid in losing weight. Because you think about it, there are 24 hours in a day, and if you're not eating 16 hours in a day, you're only eating 8 hours in a day. And so it reduces the time that you're actually eating. And that when you don't eat for a period of time, your body start to create almost like a starvation mode model. It's like you burn fat, and when you burn fat, you kind of secrete like an acidic environment which then kind of decreases your appetite in a sense. And if you ever fasted for multiple days, you tend to have a little bit of a bad breath, this acidic type like breath that you get when you actually have diabetes. So how, how intermittent fasting help with weight management is that it closes the window when you can eat, so the amount of time you can eat is less. And it also help with appetite suppression or you eat less as well. So when you eat less and have a smaller window, you lose weight. And when you lose weight, it also help with your sexual health as well. So those are the benefits of intermittent fasting. There are many, many other benefits as well. But I wanted to focus intermitt and fasting and how it helped with just sexual function and erection and something that I'm a big proponent of intermittent fasting of not eating for at least 12 hours. And if you've never done it before, I recommend that you start a short hour interval, like don't eat anything after 9pm and then eat when you wake up. And if you wake up early, try to go for maybe 12 hours, like 9am now you can drink a cup of coffee with no, no sugar, no cream. That's considered Fasting. So if you go to work at 6am and you stop eating at 9pm the night before, you can actually drink a black cup of coffee. And that will still be considered that you're fasting and then don't eat anything until 9am but if you can try to go for 16 hour fast, you can start adding an hour after every three days. So that way you can increase your tolerance to tolerate up to 16 hours of not eating. Now, I do this every day. I stop eating after 8pm and I don't eat until noon time. And when I do eat, I eat between noon and 8pm My biggest meal is lunch. And the reason why is because I'm active through the day, I burn that calories that I eat and then I eat a smaller meal for dinner. And usually it's around like 7, 7:30. And then from 8pm until I go to bed around 11pm, I drink water. And if I feel like I need to eat something, what I do is I make a cup of tea, green tea and hot tea and I drink that. That's still considered fasting. And also note that black coffee is also considered fasting. If you wake up in the morning, you need that cup of coffee like I do. I drink a black cup of coffee in the morning before I go to work.
