Does gluten-free mean no carbohydrates?

Gluten-free diets have become increasingly popular in recent years, driven by rising awareness of celiac disease and gluten sensitivity. For those with gluten intolerance or sensitivities, following a strict gluten-free diet is essential to manage symptoms and prevent complications. But for many others, going gluten-free is a lifestyle choice pursued for potential health benefits or weight loss. This raises an important question – does eliminating gluten also mean cutting out all carbohydrates?

What is gluten?

Gluten is a general name for the proteins found in wheat, rye, barley and triticale. It acts as a glue that helps foods maintain their shape, acting as a structural component in baked goods. For those with celiac disease or non-celiac gluten sensitivity, gluten triggers an abnormal immune response that causes inflammation and damage in the small intestine. This can lead to a variety of gastrointestinal and other symptoms. The only treatment for gluten-related disorders is strict adherence to a 100% gluten-free diet.

Foods containing gluten

Gluten is naturally found in foods containing wheat, barley, rye and triticale. This includes breads, baked goods, pastas, cereals, beer, etc. It can also be found in less obvious foods like sauces, salad dressings, spices, processed meat and fried foods that have been cross-contaminated. Reading labels is essential, as gluten can lurk in unexpected places. Oats are inherently gluten-free, but are often contaminated with gluten during growing and processing. Gluten-containing grains like wheat are commonly used in products to provide texture, structure and protein.

Naturally gluten-free grains and starches

While gluten-containing grains are widespread in modern diets, there are many naturally gluten-free grains and starches that make suitable substitutes:

  • Rice
  • Corn
  • Quinoa
  • Millet
  • Sorghum
  • Buckwheat
  • Arrowroot
  • Tapioca
  • Amaranth
  • Teff
  • Potato starch
  • Cassava

These gluten-free options provide a range of nutrients like carbohydrates, protein, fiber, antioxidants, vitamins and minerals. Just like wheat-based products, they can be used to make breads, baked goods, pastas, cereals, etc. Gluten-free substitutes have come a long way, providing more choice than ever. With some adjustments to recipes and techniques, it’s possible to create delicious gluten-free baked goods, breads, pizzas and other wheat-based foods.

Carbohydrates in a gluten-free diet

Going gluten-free does not inherently mean eliminating all carbohydrates from the diet. While grains like wheat, barley and rye are significant sources of carbohydrates, there are many naturally gluten-free grains and starches that can provide carbohydrates in a gluten-free diet.

Rice, corn, quinoa and starchy vegetables like potatoes and sweet potatoes are all examples of gluten-free carbohydrate sources. Furthermore, traditional gluten-free grains like millet, amaranth and teff contain similar amounts of carbohydrates as wheat. Gluten-free versions of breads, cereals, baked goods, pasta and other wheat-based products are typically made with rice, corn, potato and tapioca starch.

These gluten-free substitutes can have just as many or even more carbohydrates than their traditional counterparts. For example, a 6-inch gluten-free sandwich roll can contain 24 grams of carbohydrates, which is comparable to regular wheat bread. Gluten-free pasta may contain a similar number of carbohydrates by weight as regular wheat pasta.

So in general, it’s certainly possible for gluten-free diets to be high in carbohydrates. Those who follow a gluten-free diet have many choices to incorporate carbohydrate-containing foods that fit their preferences and health needs.

Lower carb gluten-free diets

However, going gluten-free does offer more flexibility to reduce carbohydrate intake for those who desire to do so. Eliminating wheat, barley and rye removes some significant dietary carbohydrate sources. While gluten-free substitute products exist, some people opt to minimize use of packaged gluten-free breads, baked goods and snacks.

Instead, they rely on foods that are naturally low in carbohydrates like:

  • Meat
  • Poultry
  • Fish
  • Eggs
  • Non-starchy vegetables
  • High-fat dairy
  • Nuts and seeds
  • Fats and oils
  • Avocados

A lower-carb gluten-free diet can be nutritious, satisfying and aligned with popular low-carb lifestyles like the ketogenic diet. People who specifically want to reduce carbohydrate intake may find eliminating gluten provides a jumping off point. But cutting out gluten itself does not dictate overall carbohydrate intake.

Weight loss on a gluten-free diet

Many people turn to gluten-free diets in hopes of losing weight. However, research has not conclusively shown that gluten-free diets are better for weight loss.

In most studies comparing gluten-free and gluten-containing diets, both groups lost similar amounts of weight and body fat. Overall calorie intake seems to matter more than the presence or absence of gluten itself. That said, there are some potential reasons why gluten-free diets may spur indirect weight loss for some people:

  • Eliminating major sources of carbohydrates like breads, pastas and baked goods may lower overall calorie intake, depending on substitute choices.
  • Increased attention to one’s diet and stricter food rules may improve adherence to a weight loss diet.
  • Resolution of chronic inflammation related to gluten intolerance may improve metabolic function and body composition.
  • Subtle gluten intolerances causing water retention may be reversed, spurring initial water weight loss.

But these benefits are not unique to gluten-free diets. Overall, cutting gluten itself does not guarantee weight loss or fat loss. Whether gluten-free or not, a sustained calorie deficit is needed to lose weight over time.

Key takeaways

Here are the key points to understand about carbohydrates and gluten-free diets:

  • Gluten is a protein found in wheat, barley, rye and triticale grains.
  • Gluten-free diet eliminate these gluten-containing grains.
  • However, there are many nutritious gluten-free grain and starch options.
  • Gluten-free diets can be high or low in carbohydrates.
  • Gluten-free substitute products like breads and baked goods often contain significant carbohydrates.
  • Naturally low-carb foods like vegetables, meat and eggs are gluten-free.
  • Cutting gluten itself does not automatically mean reducing carbohydrates.
  • Gluten-free diets support flexibility in managing carbohydrate intake.

So in summary, going gluten-free does not inherently equate to a no- or low-carbohydrate diet. Gluten-free foods can range from very high to very low in carbohydrates based on choices. But eliminating gluten does provide an opportunity to reduce carbohydrates for those who wish to do so.

Frequently asked questions

Do you need to eat carbohydrates on a gluten-free diet?

No, there is no requirement to eat carbohydrates on a gluten-free diet. With planning, it’s possible to follow a very low-carbohydrate or ketogenic gluten-free diet by emphasizing foods like meat, fish, eggs, dairy, healthy fats, vegetables, nuts and seeds.

What are good low-carb gluten-free foods?

Some examples of nutritious low-carb gluten-free foods include:

  • Meat: Beef, pork, lamb, chicken, turkey
  • Fish: Salmon, tuna, trout, sardines
  • Eggs
  • Non-starchy vegetables: Leafy greens, broccoli, tomatoes, peppers, zucchini
  • High-fat dairy: Cheese, full-fat yogurt, heavy cream
  • Nuts and seeds: Almonds, walnuts, sunflower seeds
  • Healthy fats: Olive oil, coconut oil, avocados

Is rice gluten-free?

Yes, rice is naturally gluten-free. This includes varieties like white rice, brown rice, basmati rice, jasmine rice and wild rice. Rice and rice flour are commonly used as gluten-free alternatives to wheat.

Is corn gluten-free?

Yes, corn is inherently gluten-free. Corn in its natural grain form, as well as cornmeal, popcorn, corn flour and other corn-based products are gluten-free and commonly used in gluten-free cooking.

Sample meal plan

Here is a sample one-day low-carb gluten-free meal plan:

Meal Foods
Breakfast Gluten-free omelet with spinach, tomato and cheese

This provides a balance of lean proteins, healthy fats, and low-carb vegetables across meals and snacks. Dessert could be berries with whipped cream. There are many possibilities for nutrient-dense gluten-free low-carb meals.


In summary, gluten-free diets do not inherently require elimination of carbohydrates. Gluten-free grain and starch alternatives provide many options for including carbohydrate-containing foods. However, going gluten-free can offer flexibility in managing carbohydrate intake. It’s certainly possible to pursue both a gluten-free and lower-carbohydrate or ketogenic eating pattern by emphasizing whole, nutritious low-carb foods.
