6:39 How to fix high blood sugar
If you’ve given up sugar but your blood sugar is still high, this is for you.
The liver is responsible for producing sugar for the small percentage of the body that requires it. If you have high blood sugar despite removing sugar from your diet, it is either caused by a liver problem or a stress problem. Stress increases cortisol, a hormone that stimulates the release of sugar.
If you wake up in the morning with high blood sugar and did not consume any sugar the day before, this is known as the dawn phenomenon. This phenomenon is caused by a long-standing liver problem associated with insulin resistance.
To fix high blood sugar, do the following:
1. Low-carb diet
2. Stop snacking
3. Reduce stress

| 0:00.0 | I don't eat sugar. Why is my blood sugar so high? You're doing everything right. You're giving up sugar. You skip the bread. You haven't had a dessert and quite some time. Yet you look at your blood test and it's like, what's going on? My blood sugar is high. Your doctor might even look at you like you're cheating when you're really not. Let me show you what's going on. There's one piece of this puzzle that a lot of people don't even know about. |
| 0:22.0 | Most people think that their blood sugar is a result of what they eat, right? Sugar, starches, |
| 0:28.7 | et cetera. Yet that's only half the story. I want to introduce you to your liver. Your liver has 500 |
| 0:36.0 | functions. It is a filter to help you detoxify, but your liver is actually a sugar factory. |
| 0:43.5 | And so there's a certain small percentage of your body that has to have sugar. Okay. So even if you don't eat sugar, these tissues, one is part of the brain and part of the kidney, and there's other tissues that |
| 0:56.1 | literally depend on sugar. |
| 0:57.6 | And so if you don't eat sugar, your liver is going to make it. |
| 1:01.2 | And when a person goes on a low sugar diet or a low carb diet, they're going to get their |
| 1:05.0 | fuel from the fat from the calories they eat, as well as the fat from their own body. |
| 1:10.9 | And it makes sugar out of things that are not sugar. |
| 1:13.7 | It'll make sugar out of fat. |
| 1:16.2 | It'll make sugar out of protein. |
| 1:18.8 | And it feeds the different parts of the tissues. |
| 1:21.2 | The question is, why is my blood sugar higher than it should be? |
| 1:24.8 | Actually, you have an off switch for this sugar. And the off switch is basically |
| 1:30.1 | insulin. If there's not enough insulin, your liver is going to be a sugar factory. Now, wait a second, |
| 1:37.9 | that's kind of conflicting information because if I'm not eating carbohydrates, I'm not going to |
| 1:42.8 | stimulate insulin. Insulin's going to go low. So then my I'm not going to stimulate insulin. |
| 1:48.7 | Insulin's going to go low, so then my body is just going to make a lot of sugar. |
| 1:54.3 | What normally happens is this hormone has been abused. |
| 2:00.7 | It's been overstimulated for many, many years, like 10 to 15 years, constantly raised, and then the cells, because they're constantly bombarded |
| 2:04.2 | with so much insulin, started to ignore this off switch to the point where you develop insulin |
