The Best Diets For Blood Sugar Balance, According To A Functional Medicine Expert

The best diets for balancing blood sugar

1. The Ketogenic Diet

The high-fat, moderate protein, low-carb ketogenic diet has exploded in popularity in the wellness world, and for good reason. This diet has demonstrated healing power for a variety of health problems. Multiple studies show the ketogenic diet’s ability to lower insulin levels, reduce inflammation, and improve insulin receptor site sensitivity, which helps the body function the way it was designed to function. In fact, the ketogenic diet can re-balance out-of-control blood sugar so well that in my functional medicine clinic it has become my gold standard for anyone wrestling with health issues like metabolic syndrome, pre-diabetes, and diabetes.

The ketogenic diet accomplishes this feat by transitioning your body from sugar burning to fat burning, so that you no longer need to rely on glucose for energy. Instead, your energy comes from ketones, which are the by-products of fat burning. Ketones are not only a more sustainable form of fuel for your body, but it keeps your blood sugar steadier than a diet fueled by low-fat, high-carb foods like high-fructose fruits, grains, and sugar. Many people who have switched to a ketogenic diet have seen their blood sugar levels normalize rapidly - research has shown (1) that symptoms of type 2 diabetes can even be reversed after just 10 weeks on a ketogenic diet!

No matter what foods you prefer, you can do a ketogenic diet just by shifting your macronutrient ratios and meal plan to focus on foods high in healthy fat, and away from foods high in carbohydrates and sugar. Even vegetarians and vegans can still do a ketogenic diet by practicing a plant-based version.

2. Intermittent Fasting

Another fantastic tool for blood sugar control is intermittent fasting or time-restricted feeding. These techniques can easily be incorporated into any diet you choose to follow. These techniques incorporate extended periods of fasting into the day and limit the window of time during which you will eat. For example, you may fast for 12 hours (overnight) between the last bite of dinner and the first bite of breakfast. Or, you may choose to fast one day per week, or even as often as every other day. Others choose to limit the window in which they will eat to 10, 8, 6, or even fewer hours, depending on how intensive they want to be.

During the eating window, you must be sure to get all your necessary calories and nutrients for the day. The rest of the 24-hour period, you do not eat. This is not as difficult as it sounds because intermittent fasting tends to suppress your appetite, and by limiting your food intake to certain windows of time, your body gets a break from constant digestion. That means it has time to rest and has more energy to devote to healing and regeneration. Intermittent fasting, or IF, is especially good for healing insulin resistance and increasing metabolism, according to multiple studies.

One study (2) tested intermittent fasting protocols on three different patients of various ages who were all diagnosed with type 2 diabetes and had been taking medication for their condition for over 10 years. The patients were required to eat a low-carb diet (think: ketogenic) in conjunction with three 24-hour fasts per week. By the end of the trial, not only did each patient lose weight, but they were all able to completely discontinue their insulin medication.

But that’s not all fasting protocols can do. Periods of fasting can also help improve (3) autoimmune symptoms from multiple conditions including type 1 diabetes, by restoring balance to the immune system and driving-down inflammation.

There are many ways to try intermittent fasting, and many levels of intensity. Which should you try? It depends on your fasting experience, tolerance, and schedule. You can check out my article here for all of the ways to fast, but some of my favorites for each level include:

IF for Beginners: The 8-6 Window Plan

Eat only between the hours of 8 a.m. and 6 p.m., allowing for 14 hours of uninterrupted fasting.

IF for Intermediates: The 12-6 Window Plan

Extend the fasting period and only eat between the hours of 12 p.m. and 6 p.m., increasing your fasting time to 18 hours.

IF for Advanced Fasters: Every-Other-Day Plan

Exactly as it sounds, eat normally every other day, and fast for a full 24 hours every other day.

IF for Super Advanced Intermittent Fasting: OMAD

This is a 23:1 fasting to eating protocol, hence its name: OMAD (one meal a day). For a full run-down on OMAD, check out my article on the subject.

3. Paleo

If fasting sounds too intense, or it’s just not for you, another great way to kick off your wellness journey and get control over your blood sugar at the same time is by trying a paleo diet. This diet focuses on clean, whole-food sources such as vegetables, fruit, meat, wild-caught fish, eggs, nuts and seeds, and healthy non-refined oils, while eliminating dairy, grains, processed foods, sugar, and legumes. This diet provides your body with ample nutrition through natural foods humans are meant to eat. And by removing the foods we know cause blood sugar spikes and processed foods containing chemical preservatives and other artificial ingredients, blood sugars often stabilize naturally.

It’s interesting that a traditional “diabetes diet” focuses on the foods a paleo diet eliminates - whole grains, dairy products, legumes, and root vegetables. It is also lower in total fat. Yet, it is less effective. In a study published in Cardiovascular Diabetology, (4) those following a paleo diet had significantly lowered glucose levels compared to those following a conventional diabetic diet.

4. AIP (Autoimmune Protocol)

This dietary strategy is similar to a paleo diet, but slightly stricter. It eliminates additional foods known to be immune stimulants for some people: eggs, nuts and seeds, and nightshade vegetables and spices (tomatoes, all peppers except black pepper, eggplant, all potatoes except sweet potatoes, tomatillos, paprika, and goji berries). Those with autoimmune blood sugar problems like type 1 diabetes and type 1.5 diabetes (also known as LADA, or Late Autoimmune Diabetes of Adulthood), can benefit from taking these additional foods out of their diets. This isn’t going to cure you, but it can help your immune system as well as your blood sugar to stabilize.

There are limited studies on the effects of an AIP diet on blood sugar specifically, but because it is so similar to a paleo diet (eliminating blood sugar spiking foods like grains, legumes, and sugar), it’s logical to conclude that this diet would be beneficial, if not more so, for blood sugar control, especially when it has an autoimmune component.

Of course, every person responds to foods and dietary strategies differently, and there may be other diets that work to balance blood sugar for some people. However, in my practice, these are the top four methods that I’ve seen yield real results in my patients.

Blood sugar balancing meals

Now that we’ve covered what diets are the best for blood sugar balance, here are some examples of my favorite blood sugar balancing meals and snacks to give you a better idea of what a daily meal plan might look like for you.

Avocado Egg Bowls

Fat is the building block of healthy and happy blood sugar levels. Your brain is made up of 60 percent fat so you want to feed it exactly what it is made of rather than depriving it. Get your healthy fats in through everybody’s favorite fruit – avocado!

Ingredients

• 1 medium avocado
• 2 pasture-raised eggs
• Sea salt and pepper to taste
• Shredded grass-fed cheese (optional)

Directions

1. Preheat the oven to 425 degrees F.
2. Cut open the avocado, remove the pit, and scoop out just enough to make room for the egg.
3. Place the avocado in a jumbo muffin tin or oven-proof ramekin to keep it from tipping over. Crack open the eggs and place one in each half of the avocado. Sprinkle it with salt and pepper to taste and cheese if desired. Bake for 15 minutes and enjoy it hot.

Nutty Chia Pudding

Creamy, pleasantly-textured chia pudding is the perfect make-ahead option and is great for those who prefer eating more plant-based. The abundant healthy fats in this pudding come from the coconut milk, chia seeds, and nuts. This recipe is also rich in blood sugar-balancing protein. I like to mix this up the night before so it is ready to go in the morning with zero effort (other than finding a spoon). This makes a large single serving or can be split up for two servings.

Ingredients

• 2 cups unsweetened coconut milk
• 1/2 teaspoon vanilla extract
• 1/4 cup desired sweetener (honey, maple syrup), optional
• 2 tablespoons peanut butter or other favorite nut butter
• 1/2 cup chia seeds
• 1/4 cup chopped walnuts or almonds

Directions

1. Place coconut milk, vanilla, sweetener (if using), and peanut or nut butter together in a blender and blend until smooth.
2. Stir in chia seeds and chopped nuts. (Or reserve the nuts right before eating, if you want them to remain crunchier.)
3. Pour into your desired container and place in the refrigerator for between 4 and 24 hours.

Omnivore Frittata

This simple frittata celebrates clean protein and even more great fats – perfect for a Sunday morning, with leftovers for the week. The mushrooms and greens promote methylation detox pathway function to help your body fight off the toxins you come across throughout the rest of your day.

Ingredients

• 8 large pasture-raised eggs
• 1/2 cup almond or coconut milk
• 1 tablespoon coconut oil
• 1/2 cup mushrooms, diced
• 1/3 cup onion, diced
• 2 cups kale or spinach
• 3 slices organic turkey bacon, cooked and chopped
• 1 cup ground organic grass-fed sausage or ground beef, cooked

Directions

1. Preheat the oven to 350 degrees F.
2. Whisk eggs together with milk, and season with salt and pepper to taste.
3. Heat coconut oil in a skillet over medium heat. Add in mushrooms and onions, and cook for about 3 minutes, then add in greens.
4. Add the eggs, bacon, and sausage to the vegetable mixture. Tilt the pan to spread the eggs evenly, and cook until the edges and bottom start to set.
5. Place in the oven and bake for 10 to 15 minutes or until the eggs are fully set.

Adaptogenic Green Smoothie

Smoothies are a quick, easy, super-nutritious breakfast, lunch, or snack option for those who like something lighter. I usually prefer to drink my breakfast, and this smoothie is packed with all of the fats you need without the load of sugar you will find in most other fruit-based beverages. Reishi is a powerful adaptogenic mushroom that will support healthy blood sugar balance with its ability to down-regulate (5) alpha-glucosidase, the enzyme responsible for breaking down starches into sugars.

Ingredients

• 2 cups full-fat unsweetened coconut milk
• 1 cup spinach, kale, or other greens of choice
• 1/2 avocado
• 1/2 green apple
• 1 tablespoon coconut oil
• 1 teaspoon reishi powder

Directions

1. Combine all ingredients in a blender, blend, and enjoy!
