A slow metabolism means there are available calories in your body, but your cells can’t properly use them. This is also known as metabolic dysfunction. The worst foods for the metabolism are often considered healthy, but consuming them could be the reason you’re struggling to lose weight.
Fruit juice is often considered a healthy choice, but it’s actually about 55% fructose. Fructose can only be metabolized by the liver, so consuming it in high amounts can lead to liver stress, fatty liver, increased belly fat, and metabolic problems.
Seed oils are often labeled as “heart-healthy,” but are highly processed, genetically modified, and typically contain herbicides. Up to 30% of daily calories in the average diet come from seed oils, which can contribute to inflammation and metabolic dysfunction.
Other foods like oat milk and agave nectar spike blood sugar and insulin, disrupting metabolic health, preventing weight loss, and slowing your metabolism over time.

| 0:00.0 | Let's talk about the seven foods that will destroy your metabolism. |
| 0:04.0 | First of all, when I talk about a destroyed metabolism, I am talking about a slow metabolism. |
| 0:08.0 | So we can go a longer period of time with a smaller amount of calories. |
| 0:14.0 | That's actually a damaged metabolism. |
| 0:17.0 | Because if you look at the cells and look deeply into the cells, you see this little mitochondria, |
| 0:22.0 | these little guys adapt not by slowing down your metabolism, but by making it run longer on smaller |
| 0:28.9 | amount of calories. So the real situation that's happening with the damaged metabolism is there's |
| 0:34.6 | all of these available calories, but our body cannot use them. |
| 0:40.4 | So if you really want to know what's happening with metabolic dysfunction, you have all of this |
| 0:45.1 | fuel available, but it's not available to the cells. So if you were in your house, but you had a chain |
| 0:52.8 | lock on your refrigerator and your pantry, |
| 0:55.6 | the food's there, but you just don't have access to it. |
| 0:58.9 | So then the body copes with that and it adapts by becoming more efficient, but really it's |
| 1:03.4 | not a good thing because you gain weight, okay, and you have health problems. |
| 1:08.2 | So today I'm going to talk about foods that destroy your metabolism |
| 1:11.3 | that you might think are healthy. In fact, you might have in your refrigerator, in your pantry, |
| 1:17.8 | the foods I'm going to talk about. So let's talk about number one, fruit juice, 100% squeezed |
| 1:24.8 | orange juice. The problem is they're taking out all of the fiber. They usually |
| 1:29.7 | pasteurize it. They cook it. And they have to add the vitamin C back in there because heat |
| 1:35.0 | destroys the vitamin C and they might promote it as being high in vitamin C. But it's the added |
| 1:39.5 | vitamin C synthetically, which by the way, it comes from cornstarch and sulfuric acid, very different |
| 1:46.6 | than the vitamin C in nature. But the big problem with fruit juice is that it's 55% fructose. |
