A prediabetes diagnosis can be scary. After all, diabetes is typically thought to be a chronic, progressive condition. You probably have a lot of questions – a big one being “how do I stop this from progressing to type 2 diabetes? What should I do? What can I eat?” It can be overwhelming. But there’s some good news – it is possible to reverse prediabetes and prevent type 2 – and what we eat plays a big role here.
Prediabetes develops when blood glucose (sugar) levels are higher than normal, but not quite high enough to be classified as type 2 diabetes. When glucose levels in the blood start to rise, the body produces insulin - a hormone that helps glucose enter the cells to be used as energy. In the development of prediabetes, your cells don’t respond to insulin as they should (this is called insulin resistance) and the pancreas responds by making even more insulin. Once the pancreas is unable to keep up, glucose levels continue to rise above normal levels and prediabetes develops.
The stats are a little scary: some experts estimate that as many as 70% of people with prediabetes will develop type 2 in their lifetime¹. But, this is not inevitable. You can absolutely take control of your health, and prediabetes can be reversed. A major factor in preventing prediabetes from progressing to type 2 is diet – and we’ll get into more detail on that.
While the exact cause of prediabetes is unknown, lifestyle, family history and genetics can all play a role. But the underlying root issue is insulin resistance - people with prediabetes aren’t processing glucose “normally” anymore. Most of the glucose in our bodies comes from the food we eat, and when someone with prediabetes or type 2 diabetes eats carbohydrates or sugar, it causes their blood sugar to rise above a healthy level.
One of the most studied diets for reversing diabetes and prediabetes is a low carbohydrate diet² that’s personalized to your carb tolerance. People with a high carb tolerance might be able to eat a carbohydrate-heavy diet and keep their blood sugar in a normal range, but someone with prediabetes and a low carb tolerance may experience chronic blood sugar spikes and struggle with fatigue, weight gain, and more.
Since carbohydrates turn into sugar in your body, restricting them in your diet can be very successful in reversing prediabetes and preventing its progression to type 2.
Virta utilizes a “well formulated ketogenic diet” to reverse the progression of prediabetes. This means eating foods that have moderate protein, low carbohydrates, and have an adequate amount of fat to stay full. But it’s not just about the food – it’s about the support. Virta provides 1:1 virtual coaching to help make this lifestyle stick – see if you’re eligible for Virta here.
If you’re following a low-carb diet to reverse your prediabetes, here are a few foods you might want to add to your grocery list – and ones you should limit as much as possible or steer clear of altogether.
It’s important to watch your carb intake if you have prediabetes. While some foods like brown rice, potatoes and oatmeal are typically considered “healthy,” they could also spike your blood sugar. That’s why it can be a good idea to use the glycemic index (GI) as a tool to determine how a particular food could affect your blood sugar.
In addition to watching your carb intake and avoiding high GI foods, you also want to avoid these foods if you have prediabetes.
Here are a few meals you might consider if you have prediabetes and are following a low-carb diet. These meals are all low on carbohydrates and higher on fats that will keep you full for longer.
Scrambled eggs with cheese and sausage
Unsweetened coffee (or sweetened with a 0 carb sweetener like Stevia) with heavy cream
Vegetarian option: Full fat yogurt with berries or coconut flour pancakes
Baked salmon with hollandaise sauce, and a side salad made of leafy greens and a full-fat dressing (watch out for any hidden sugars in dressings and sauces!)
Vegetarian option: Tofu curry made with full fat coconut milk
Steak with brussel sprouts
Vegetarian option: Palak paneer or curried cauliflower soup
Berries with heavy cream
A prediabetes diagnosis can be daunting, but it doesn’t have to mean you will have prediabetes forever, or even progress to type 2 diabetes.
Making some changes to your lifestyle can effectively reverse prediabetes.
Short answer: yes, in moderation. Because fruit is a natural source of sugar, it’s important to limit how much you eat, and choose fruits with lower levels of sugar, like berries and kiwi.
People with prediabetes who are following a low carb diet have lots of options for breakfast, including eggs, meats like breakfast sausage, and full fat yogurts, as well as smoothies that contain low-sugar fruits and veggies.
For people with prediabetes who are dealing with high blood sugar and choose to drink alcohol, it should be consumed in moderation. There are alcohols that are low in carbohydrates – like vodka and dry wines – but be wary of cocktails with sugary mixers.
