Is A Banana Allowed On Keto Diet, And How Many? 

Written By:

Post Date – Update:

When people go on a keto, and low-carb diet, one of the things they want to know is whether or not a banana will be allowed on a keto diet. The banana is considered a nutritious and healthy fruit for most people.

A banana is not a fruit you should eat on a keto or low-carb diet. Banana is relatively high in carbohydrates and sugars. Compared to other fruit choices of strawberries and blackberries, bananas are incredibly high in carbohydrates and sugars. One medium banana has about the same carbohydrates as a snickers candy bar.

Bananas And Keto Or Low Carb Diets

Banana is a fruit that is relatively high in sugar and carbohydrates. A banana has many other nutritional values, but its carbohydrate and sugar values are relatively high.

Below is the nutritional value for one medium banana that is between 7 to 8 inches long. This would be a standard-size banana that most people would eat as one serving

1 Medium Banana –
7” to 7.7/8” long (118 gram
Nutritionals Values
Calories 105
Total Fat0,4 grams
Cholesterol0 mg
Sodium 1 mg
Potassium422 mg
Total Carbohydrates 27 grams
Dietary Fiber 3.1 grams
Sugars 14 grams
Protein 1.3 grams
Nutritional Value Banana

As you can see from this chart, the banana has 27 g of carbohydrates for one medium banana and 14 g of sugar. This is relatively high for any fruit. For most people on the keto or low-carb diet, eating one banana daily will throw them out of ketosis.

If you need to stay under 50 g of carbohydrates per day to stay in ketosis, 27 g will be over half your daily allowance. Essentially, this would mean that this would be the significant carbohydrate you would need to eat daily. T

That is just not reasonable because you will be eating vegetables and other things which will also have some carbohydrates in them.

We do not recommend eating a banana on a low-carb or keto diet. A banana is simply too high in natural sugars and carbohydrates.

Banana Vs. Strawberries Nutritional Values

Banana Vs. Strawberries

Some people want to know whether or not they can eat some strawberries on a low-carb or keto diet. Strawberries are a better choice but have natural sugars and carbohydrates.

When compared to a banana, a strawberry is a much better choice than eating a banana. You can compare the nutritional value below between 1 cup of strawberries and one medium banana.

Nutritional Value Banana Vs. Strawberries

As you can see from the list above, strawberries have fewer carbohydrates and fewer sugars than a banana. It has a healthy amount of natural sugars and a healthy amount of carbohydrates. This would make strawberries a better choice than eating a banana on a keto or low-carb diet.

Bananas Vs. Blackberries Nutritional Value

Banana Vs. Blackberries

Another fruit that most people consider a better choice is blackberries. Compared to a banana, blackberry is also a much better choice.

You can see in the nutritional chart follow that one cup of blackberries is lower in carbohydrates and sugar than a banana.

Nutritional Value Banana Vs. Blackberries

Blackberries have much lower carbohydrates and sugars than a banana. So they would be a better choice for fruit on a low-carb and keto diet. We still do not recommend eating blackberries or strawberries because they are still relatively high in carbs and sugar.

Blackberries are higher in carbs than strawberries Blackberries and strawberries have the same amount of grams of sugar.

Banana Vs. A Snickers Bar Nutritional Values

Banana Vs. Snickers

To compare how high the carbohydrates are in a banana, we wanted to compare a snickers bar. We are not saying that a snickers bar is a better choice, but we wanted to compare the nutritional value so that you could see how similar they were as far as their grams of carbohydrates.

Below is the nutritional value of comparing a regular-size snickers bar with a medium size banana. When you look at the carbohydrate value between them, you can see a medium banana and a snickers bar have very similar carbohydrates.

Banana – 1 Medium
Nutritionals Values
Snickers Bar 1.56 ounces
Nutritional Value
Calories 105215
Total Fat0,4 grams11 grams
Cholesterol0 mg4 mg
Sodium 1 mg83 mg
Total Carbohydrates 27 grams28 grams
Dietary Fiber 3.1 grams0.8 grams

Nutritional Value Banana Vs. Snickers Bar

A medium-sized banana has 27 g of carbohydrates, whereas a regular snickers bar has 28 g. The sugar in a banana is 14 g, and a snicker bar is 20 g.

Of course, the snickers bar has higher calories and is not as nutritionally sound as a banana, but their carbohydrates as similar. We are not saying that a snickers bar and a banana are the same; in fact, we know that a banana is a much healthier choice for you than a snickers bar.

But we wanted to show how unhealthy a banana is on a keto and low-carb diet. Bananas should not be eaten on a keto or low-carb lifestyle. A banana’s just very high in both carbohydrates and sugars.
