3 Foods You MUST Avoid to Reverse Type 2 Diabetes Naturally

I’m going to start this article with two secrets. These are things that most other diabetes experts won’t tell you, but I believe you need to know.

Number one is that you can reverse type 2 diabetes. Depending on the person, it can sometimes be fully reversed to the point of not having any symptoms of the disease at all, or if not, the body’s health can still be improved, usually to a drastic degree.

Number two is that most doctors won’t tell you this – not because they are malicious, but simply because they don’t know it can be done either! Oftentimes, our clients’ doctors are in shock when they see their numbers after working with us for 3 months.

It’s not normal for people to be reducing or getting off of their diabetes medications. It’s not normal to lower your A1c by multiple points, back into non-diabetic range. But in our coaching program, those things ARE normal. Not just possible, but normal.

I don’t know about you, but that’s the kind of normal that I want to choose in my life. So if you agree, keep watching. Because today I’m going to tell you about 3 foods you need to avoid if you want to join the club in making reversing type 2 diabetes a reality.

The Downsides of Meat

You can tell a lot about a person’s likelihood of developing type 2 diabetes by where they live and what they eat – and to be completely honest, the where they live part is only important because of what they eat there.

For instance, if you live in Okinawa, Japan, there’s a 2.3% chance that you have diabetes. Whereas in the USA, there’s a 14.7% chance that you have diabetes. To summarize that, you are SIX TIMES more likely to have type 2 diabetes if you live in the United States in comparison to Okinawa.

Why? Well, people eating a traditional Okinawan diet mostly or entirely avoid our recommended 3 foods to avoid in order to reverse diabetes. Without even knowing it, they are following the Mastering Diabetes Method!

Food number one that they avoid is animal products – especially meat. Many studies have assessed the association between meat consumption and development of type 2 diabetes. In a study of 69,554 women (The Nurses Health Study), researchers found that for every additional serving of meat per day, the risk of developing type 2 diabetes increased by the following amounts:

  • Red meat: A 26% increased risk of diabetes.
  • All processed meats: A 38% increased risk of diabetes.
  • Bacon: A 73% increased risk of diabetes.
  • Hot dogs: A 49% increased risk of diabetes.

Yes, we are aware that those numbers are alarming. That’s why meat is on our must-avoid list for type 2 diabetes!

There are multiple mechanisms for this association and diving into the details of that is a topic for another video. The important message for right now is that diets high in meat products, especially red and processed meats, promote the development of type 2 diabetes. So our advice is: don’t eat them!

People in Okinawa, where diabetes rates are some of the lowest in the world, eat very little meat. In fact, they eat mostly carbohydrates! 80-85% of the traditional Okinawan diet is carbohydrates, with a focus on sweet potatoes, rice, and vegetables. Not only are these foods plant-based, but they are also whole foods… which brings me to the second kind of food to avoid if you want to reverse type 2 diabetes.

Eat It How Nature Made It

It wouldn’t be fair to put all the blame on meat. There are other food culprits to call out here. Our second top food to take out of your diet if you want to reverse type 2 diabetes is highly processed foods.

Time for some more alarming statistics. A 2021 meta-analysis found that for every 10% increase in your consumption of ultra-processed foods, your risk of developing type 2 diabetes increases by 15%. Another study of 13,608 adults in Canada found that those who ate the highest amounts of ultra-processed foods had a 37% higher risk of developing type 2 diabetes, and another recent systematic review and meta-analysis found a 31% increased risk.

Like meat, the reasons for this association are myriad, but the short story is that your body just isn’t built to eat these foods. Although they’ve been around for your whole life, they are very new to the evolution of the human species. Your body is built to eat food in the forms it is found in nature. Highly processed sugars, refined fats like vegetable oils, refined grains like white flour, and the lack of fiber and other vitamins and minerals are some of the things that just don’t work well for your body and contribute to the development of type 2 diabetes. Moral of the story: Eat whole foods.

Trim the Fat

Now you might be thinking that obviously refined sugar is the biggest concern. Our evidence-based take is that the biggest issue for type 2 diabetes is not processed sugar as most might think, but actually processed fat – although the two often travel together such as in donuts, ice cream, cookies, pastries, and the like.

I know I started this video with two secrets, but the biggest secret of the whole video might be this one: Insulin resistance, which is the root cause of type 2 diabetes, is caused by intramyocellular lipids, AKA the buildup of fat inside your cells. The more fat you eat, the less efficiently your body can use insulin to bring glucose out of the bloodstream and into your cells to be used for energy.

For this reason, we recommend eating no more than 10g of fat per meal. The easiest way to overdo fat is to consume refined fats like oils. It’s commonplace to start basically every recipe with a drizzle of olive oil, but that oil is unnaturally high in fat (not to mention calories, if weight is a concern). And we don’t want to be normal, remember? Having a progressive chronic disease is normal, and we know you’re with us when we say that we do not want to be part of that statistic. Plus, you’ll be surprised to find how easy it is to cook without oils! And when you avoid processed foods, you’ll naturally avoid most other refined fats too.

Let’s Reverse Type 2 Diabetes!

So now you know the truth: If you have type 2 diabetes, you aren’t sentenced to a life of progressive disease and ever-increasing medications and complications. You can not only get better, but maybe even reverse the condition. And if you don’t have type 2 diabetes, you can prevent it from ever developing.

And the 3 most important foods to avoid in order to make those things happen?

  • Meat
  • Processed foods 
  • Refined fats

Remove those foods from your daily diet and watch your health improve dramatically, and quickly.
