/ / / Is Sourdough Low In Carbs? Can I eat it in my diet?

As the number of people try to eat healthier, keto and low carb diets are on the rise. You may be wondering if you can eat your favourite sourdough bread while you’re on a keto diet. Let’s find out!

A low carb diet is for those who are following a 50-150 gram limit of carbs per day with a high protein intake. On the other hand, the keto diet is for those who are following an even stricter carb limit, and a moderate protein intake.

The fermentation process of sourdough reduces carbohydrates. The keto diet requires an extremely low limit of carb consumption. This limit may be hard to follow if you want to eat standard sourdough. But with a few tweaks, you can include it in your diet.

How Many Carbohydrates Can You Have When Eating a Ketogenic Diet?

A ketogenic diet limits the consumption of carbohydrates. In this diet, you let your body use its stored fat as a source of energy. The process is called ketosis. If you’re new or just trying out a keto diet, it’s advised that you limit your carbohydrates consumption to under 50 grams per day.

This 50 gram carb limit continues for quite some time. You will follow it until your body gets used to ketosis. Once your body adapts, you slowly increase your carb intake. You may be able to consume up to 100g of carbohydrates a day. This is the best time to start eating sourdough bread, but how much is ok?

How many carbohydrates are in sourdough bread?

The fermentation process of sourdough consumes some of the starch and sugars in the dough. The result is a lower amount of carbohydrates in the finished loaf. The number of carbs in sourdough will vary depending on what type of bread is eaten. Some examples are listed below for 1 medium slice of sourdough bread which is 36 grams.

Type of BreadAmount of Carbohydrates (g)
German Rye Sourdough Bread 16
White sourdough bread18.5
Whole wheat sourdough bread 16.8

Does sourdough bread have more carbohydrates than standard white bread?

No, sourdough bread contains fewer carbohydrates compared to standard white bread. Sourdough made with whole wheat flour contains fewer carbohydrates. But even sourdough white bread has a relatively lower amount of carbs compared to standard yeasted bread. Take a look at their comparison listed below, as well as some other types of bread.

These examples are based on a serving of 36g per slice. 

Types of BreadAmount of carbohydrates (g)
Sourdough Whole Wheat Bread 16.8
Standard Whole Wheat Bread18.8
Sourdough German Rye Bread  16.8
Standard German Rye Bread18.8
White Sourdough Bread18.5
Standard White Bread 20.5

As you can see, a bread made with sourdough is usually 2 grams lower than standard bread (based on a 36g serving).

How much fibre is in sourdough bread?

When thinking of the nutritional composition of sourdough bread, its fibre content should also be considered. Fibre (or dietary fibre as it is often referred to) is a type of carbohydrate that isn’t consumed in our body. It absorbs the waste products that our body doesn’t want.

As fibre is included in the total amount of carbohydrates listed, to get the true number of carbs ingested, we need to subtract it from the total amount. Look at the table below to get an idea:

This example is also based on a 36g serving.

BreadTotal CarbsFibreNet Carbs
White Sourdough Bread18.50.817.7
Whole Wheat Sourdough Bread16.82.214.6
Rye Sourdough Bread161.814.2

For home bakers who are trying to keep their carb intake down, you might want to use a longer fermentation period. This will result in the yeast and lactic bacteria consuming more sugars and lowering the final carb content.

How many calories are in sourdough bread?

As the carbohydrates of sourdough bread are lower because of the fermentation process, the number of calories will also be slightly lower. However, the number of calories will still differ depending on the type of flour used and its fermentation time.

Type of BreadCaloriesServing based from
German Sourdough Rye Bread89g43g
Whole Wheat Sourdough Bread114g45g
White Sourdough Bread100g45g

How many fats are in sourdough bread?

While the fat content of most bread isn’t typically high. This is because the fermentation process will also reduce the fat content. The fat level will still vary depending on what type of flour was used.

Type of BreadFatsServing based from
German Sourdough Rye Bread0.4g43g
Whole Wheat Sourdough Bread2.3g45g
White Sourdough Bread0.8g45g

How much protein is in sourdough bread?

There are some reports of the protein and gluten content of sourdough being lower than standard bread because of the fermentation process. But of course, the amount of protein in the bread is based on the flour used to make it.

The stretching, folding, or kneading you do will activate and strengthen the gluten network of the dough. It doesn’t increase the amount of protein. Over-fermenting, when lactic acids actually consume the gluten reduces the protein content of the bread.

A typical large slice of 56 gram sourdough bread has a protein content of 6 grams.
