For those following a ketogenic diet, one of the biggest challenges is finding suitable alternatives for high-carb staples like flour. Flour is a fundamental ingredient in many foods, and regular wheat flour is typically off-limits on keto due to its high carbohydrate content. This article explores the relationship between wheat flour and the keto diet, examining different types of flours, their nutritional profiles, and keto-friendly alternatives that allow you to enjoy your favorite baked goods without compromising your diet.
Understanding Flour and the Keto Diet
The ketogenic diet is based on consuming high-fat, moderate-protein, and very low-carb foods. Nutritionists often advise against high-carb foods like white rice, pasta, and traditional baked goods. Since flour is a primary ingredient in many of these items, understanding its composition is crucial.
Composition of Flour
Flour is primarily derived from grains, with wheat being the most common source. The type of flour varies depending on which parts of the grain are retained during the milling process. A grain consists of three main parts:
- Endosperm: The starchy center of the grain, making up most simple white flours.
- Bran: The outer husk of the grain, adding texture, color, and fiber to flour.
- Germ: The reproductive center, containing the majority of the nutrients.
Is Wheat Flour Keto-Friendly?
The short answer is no. Wheat flour is not keto-friendly because it is high in carbohydrates. Wheat flour contains approximately 70% carbohydrates, making it unsuitable for a ketogenic diet. Those following a keto diet should avoid wheat flour to maintain nutritional ketosis.
The Glycemic Index and Glycemic Load
Some flours, like Keto Wheat Flour, rank low on the glycemic index, with an average value of 31 (foods with a glycemic index value less than 55 are considered low-glycemic index foods). They also have a low glycemic load, at just 1 per serving. Glycemic load values of 10 or less are considered low. Both glycemic index and glycemic load are useful for helping people identify which types and amounts of foods will produce relatively lower blood glucose responses after consumption.

Keto-Friendly Flour Alternatives
Luckily, going keto doesn’t mean saying goodbye to baked goods forever. You only need to substitute high-carb wheat flour with keto-friendly options, and there are many low-carb flour alternatives to make your favorite sweet treats and indulge in your favorite goodies.
Almond Flour
Almond flour is the most popular keto-friendly flour. It is made from peeled and ground almonds and is nutrient-dense. Almond flour is particularly abundant in vitamin E, which is important for vision, reproduction, and blood, brain, and skin health. Unlike wheat-based flour, which causes spikes in blood sugar levels, almond flour has a low glycemic index.
- Carb Count: Almond flour contains only 3 grams of total carbs and 1 gram of net carbs per 2-tablespoon (14-gram) serving.
- Usage: Almond flour can be used as a 1-to-1 substitute for wheat flour in baking, but baked goods containing almond flour tend to be a little spongy. You can also use it as a breading for fried, air-fried, or baked foods, but its main use is for keto baked goods.
- Best for: Baking, breading
- Recipes: Keto Bread, Keto Blueberry Muffins, Keto Almond Flour Pancakes
Coconut Flour
Coconut flour is made from ground and dried coconut meat, giving it a mildly nutty flavor. The fat content in coconut flour is mostly made up of medium-chain triglycerides (MCT), popular for their weight loss benefits.
- Carb Count: A 2-tablespoon (15-gram) serving provides 9 grams of total carbs and 4 grams of net carbs.
- Usage: In most recipes, you need only a small amount of coconut flour, and it absorbs lots of liquid. Using it as a 1-to-1 substitute for flour will result in an extremely dry product unless you add extra liquid ingredients. For this reason, this flour is best used in recipes that were specifically developed for coconut flour. It also makes an excellent thickener, but keep in mind that you may taste that hint of coconut.
- Best for: Baking desserts, thickening
- Recipes: Keto Coconut Flour Cookies, Keto Coconut Flour Chocolate Cake, Keto Biscuits
Flaxseed Meal
Flaxseed meal is made from ground flaxseeds, which are low in carbs and rich in potentially anti-inflammatory omega-3 fats.
- Carb Count: Containing 4 grams of total carbs and 0 grams of net carbs per 2-tablespoon (14-gram) serving.
- Usage: Like chia flour, it absorbs a great deal of liquid, so it’s usually mixed with other keto-friendly flours in baking. However, flaxseed meal is commonly used on its own or with chia seeds to make crackers.
- Best for: Crackers
- Recipes: Keto Flaxseed Crackers, Flaxseed Wraps, Keto Flaxseed Cinnamon Bun Muffins
Chia Flour
Chia flour is made from ground chia seeds, loaded with soluble fiber.

- Carb Count: A 2-tablespoon (12-gram) serving of ground chia seeds contains 5 grams of total carbs and 0 grams of net carbs.
- Usage: Chia flour isn’t commonly used in keto baking recipes. You’ll typically mix it with other flours when baking. If you’re looking for dessert ideas outside of baking, though, both whole chia seeds and ground chia seeds can be used to make an excellent low carb, high fiber pudding.
- Best for: Baking
- Recipes: Keto Bread in Bread Machine, Chocolate and Coffee Brownies, Keto Chia Seed Chocolate Pudding
Oat Fiber
Oat fiber is made from the crushed husks of oats.
- Carb Count: One teaspoon (4 grams) contains 4 grams of total carbs and 1 gram of net carbs.
- Usage: Recipes don’t often use oat fiber as a standalone flour but instead use it in combination with other low carb flours.
- Best for: Baking
- Recipes: Keto Oat Fiber Muffins, Oat Fiber Keto Buttermilk Pancakes, Keto Low Carb Waffles
Lupin Flour
Lupin flour is made from sweet lupin beans, a close relative to peanuts and soybeans.
- Carb Count: A 1/4-cup (28-gram) serving provides 11 grams of total carbs and 1 gram of net carbs.
- Usage: Although it’s most frequently used for pasta, many baking recipes feature a mixture of lupin flour and coconut flour or almond flour.
- Best for: Pasta
- Recipes: Lupin Flour Fettuccine Noodles, Keto Lupin Flour Chocolate Chip Cookies, Keto Lupin Flour Biscuits
Psyllium Husks
Psyllium husks, which are rich in fiber, are the key ingredient in many fiber supplements.
- Carb Count: One tablespoon (9 grams) contains 8 grams of total carbs and 1 gram of net carbs.
- Usage: Adding a little bit of psyllium husk powder to keto recipes made with almond flour provides a more bread-like texture, but, again, it’s typically mixed with other flours.
- Best for: Baking
- Recipes: Easy Low Carb Keto Buns, Easy Low Carb Bread Recipe, 90-Second Keto Bread
Pork Rind Crumbs
Crushed pork rinds (fried pork skins) make a great breading for fried, air-fried, or baked keto foods.
- Carb Count: Pork rind dust is totally free of carbs.
- Usage: It’s a great alternative to breadcrumbs as well, so you can use it to make meatballs, meatloaves, and many other recipes that are typically high in carbs.
- Best for: Breading, meatballs
- Recipes: Pork Rind Chicken Tenders, Keto Meatballs, Keto Seasoned Bread Crumbs
"Keto Wheat Flour": An Oxymoron?
Keto Wheat Flour might sound like an oxymoron, but it actually exists! It has just 4g net carbs per serving, and its total net carbs are 80% less than that of all-purpose wheat flour. This flour also ranks low on the glycemic index, with an average value of 31, and a low glycemic load, at just 1 per serving.

Because it’s wheat-based, it can emulate the flavors and textures of conventional wheat-flour baking. The Keto Wheat Flour formula contains wheat, and thus gluten, it yields a strong, elastic dough and bread with a soft, tender texture similar to what you’d expect from a traditional loaf. And bonus: it also has that classic wheat-y smell that’s oh-so-familiar in bread.
Keto Wheat Flour can be swapped 1:1 for all-purpose flour in a recipe by volume or weight. For biscuits with a softer, more tender texture, increase the liquid called for in the recipe by 25%. For yeast breads, increase the liquid in the dough by 2 tablespoons per 1 cup (120g) Keto Wheat Flour. Keto Wheat Flour is particularly great for baked goods with a soft or moist texture, such as muffins, pancakes, or bread. On the other hand, it’s best not to use it for any baked good with a crisp or crunchy texture, as it won’t yield a final product that breaks with a snap.
Adjust Your Expectations
Keto Wheat Flour can easily be subbed into all-purpose flour recipes and performs similarly when baked. But at the end of the day, it's a different product than the regular flour you might be used to, which means your final baked goods will also turn out a little differently, both in texture and flavor. The flavor and texture won’t be entirely the same - it will likely have a stronger "wheat" taste and sturdier texture, for instance - but the baked product will still be delicious.
Tips for Using Keto Flours
- Adjust Liquids: Keto flour and regular flour absorb moisture differently. Low-carb flour also requires more liquid to achieve the right consistency.
- Combine Flours: Recipes often use a combination of low-carb flours to achieve the desired texture and taste. High fiber additions like lupin flour, chia flour, flaxseed meal, psyllium husk powder, and oat fiber can be added to them to improve the texture and taste of baked foods.
- Consider Net Carbs: It's more important to consider net carbs than total carbs when following a low-carb or keto diet. Net carbs are the carbohydrates that your body digests and absorbs, which are calculated by subtracting dietary fiber and sugar alcohols from the total number of carbohydrates in a food item.
