Bananas And Low-Carb Diets: A Healthy Match?

Bananas are a convenient, tasty, and nutritious snack, but are they suitable for a low-carb diet? Carbohydrates are an important source of energy, but many people choose to limit their intake. A low-carb diet can have benefits such as increased weight loss and improved blood sugar control. On a low-carb diet, certain foods such as bread, sweets, and starchy vegetables are typically limited. Fruits can also be high in carbs, but many are high in fiber, which reduces the net carb count. So, are bananas a good choice for those on a low-carb diet?

Bananas are not keto-friendly

On a keto diet, the goal is to put the body into a state of ketosis, where it burns fat for fuel instead of carbohydrates. To achieve this, it is recommended to limit carbohydrate intake to 20-50 grams of net carbs per day. Net carbs are calculated by subtracting the fibre content from the total number of carbohydrates.

Bananas are relatively high in net carbs, with one medium banana containing more than 20 grams. This means that a single banana could blow your entire daily carb allowance.

While bananas are not keto-friendly, other fruits such as avocados, berries, and coconuts can be enjoyed in moderation on a keto diet. These fruits are lower in net carbs and can be part of a nutritious keto meal plan.

Net carbs in bananas

The net carb count in bananas varies depending on the size of the fruit. According to the USDA, a small banana (6" to 6-7/8" long) contains 23.07g total carbs, 2.6g fiber, and 12.35g sugar, which equates to 20.47g net carbs. A medium-sized banana (7" to 7-7/8" long) has 26.95g total carbs, 3.1g fiber, and 14.43g sugar, resulting in 23.85g net carbs.

For a large banana (8" to 8-7/8" long), the net carb count is 27.56g, calculated from its 31.06g total carbs, 3.5g fiber, and 16.63g sugar. An extra-large banana (9" or longer) contains 30.72g net carbs, derived from 34.72g total carbs, 4g fiber, and 18.59g sugar.

The net carb content of a banana can also be calculated as the total carbohydrates minus the fiber content. For example, a medium banana with 27g of carbohydrates and 3g of fiber would have 24g of net carbs.

Bananas are not considered keto-friendly due to their relatively high net carb content, which can affect ketosis. However, they are nutritious and provide various health benefits, including vitamins, minerals, and antioxidants.

Healthier alternatives to bananas

Bananas are tasty, but they are a bit of a carb bomb. A medium-sized banana contains around 20-27 grams of net carbs, which is a lot considering that low-carb diets usually allow for 20-130 grams of carbs per day.

Avocados

Avocados are a nutritional powerhouse, containing healthy fats, fibre, and potassium. They are also low in carbs, with only 9 grams of carbs per 100 grams of fruit. Avocados are a versatile fruit that can be enjoyed in many ways, such as on toast, in a dip, or even by themselves.

Berries

Berries, such as strawberries, blueberries, and raspberries, are packed with antioxidants and fibre, making them a perfect way to satisfy your sweet tooth without the carb crash. They are also very versatile and can be eaten fresh, frozen, or added to your favourite low-carb recipes. A serving of half a cup of blueberries, for example, provides a good balance between nutrient content and carbohydrate intake.

Olives

Olives are a savoury surprise on this list, but they are a great low-carb option. They are packed with healthy fats, antioxidants, and other compounds that can help fight inflammation and keep blood pressure in check. Olives are also very versatile and can be snacked on, added to salads, or used in various dishes.

Melons

Melons are a great way to stay hydrated, as they are full of water. They are also naturally sweet and low in calories, making them a guilt-free snack. Cantaloupe, honeydew, and watermelon are all good options, with around 6-9 grams of carbs per 100 grams.

Peaches

Peaches are a juicy and sweet treat, packed with vitamins A and C, potassium, and fibre. A medium peach has around 10 grams of carbs per 100 grams, making it a reasonable low-carb option.

Kiwis

Kiwis are a tangy and vitamin C-rich fruit. They are also low in carbs, with around 9 grams of carbs per 100 grams. Kiwis can be enjoyed in many ways, such as by themselves, in salads, or blended into smoothies.

Fruits to avoid on keto

A keto diet is a restrictive eating plan focused on extremely low-carbohydrate consumption. People following the keto diet are instructed to limit carbohydrates to less than 50 grams per day, with some sources suggesting no more than 20 grams. This means that many fruits, which are typically high in carbohydrates, are off the menu. Here is a list of fruits to avoid when following a keto diet:

• Bananas: According to the USDA, one banana contains more than 20 grams of net carbs, which means you may exceed your daily allowance with just one banana.
• Apples: Apples are a high-carb fruit, with one small apple containing around 21 grams of carbs.
• Grapes: Grapes are naturally high in carbs, with just half a cup containing around 15 grams.
• Mangoes: Like bananas, mangoes are also high in carbs, with half a cup containing around 23 grams.
• Oranges: Oranges are relatively lower in carbs than other fruits, but still contain around 12 grams of carbs per fruit.
• Pineapple: Pineapple is high in carbs and can easily exceed your daily allowance, with one cup containing around 22 grams of carbs.

While following a keto diet, it is important to focus on low-carb and low-sugar fruits such as avocados, tomatoes, berries, and watermelon. These fruits can be safely consumed in moderation while still adhering to the strict carb limits of a keto diet.

Fruits to eat on keto

Bananas are not considered keto-friendly due to their high carb content. One medium-sized banana contains around 24 grams of net carbs, which is more than many people's daily carb limit on a keto diet.

So, what fruits can you eat on a keto diet? Here are some keto-friendly fruits to incorporate into your diet:

• Avocados are often used like a vegetable in savory dishes, but they are actually a seed-bearing fruit. They are promoted for their rich and healthy fat content and are also keto-friendly as they are low carb. Avocados have around 8.5 grams of carbohydrates, 6.7 grams of fiber, and 14.7 grams of fat per 3.5-ounce fruit (a 100-gram serving). They also contain various essential nutrients, including vitamin C, vitamin K, potassium, and folate.
• Tomatoes are another low-carb fruit suitable for people following a keto diet. One medium tomato (123 grams) provides 4.78 grams of carbs and 1.48 grams of fiber per serving, and a cup of cherry tomatoes (149 grams) has roughly 5.8 grams of carbs and 1.79 grams of fiber. Tomatoes are also a great source of lycopene, beta carotene, vitamin C, potassium, and folate.
• Lemons are a particularly solid choice for the keto diet. An average-sized lemon contains about 6 grams of carbs and 1.8 grams of fiber, accounting for around 4.2 grams of net carbs. Lemons are also high in vitamin C and are considered a low-glycemic food that will not cause spikes in blood glucose.
• Strawberries are considered a low-carb and keto-friendly fruit, with around 11.7 carbs and 3 grams of fiber per 1 cup of halved berries (a 152-gram) serving. They also contain antioxidants, including vitamin C and lycopene, as well as manganese, calcium, and folate.
• Blackberries have a comparatively low carb count (especially when compared to blueberries). One cup (144 grams) of blackberries contains 13.8 grams of carbohydrates and 7.6 grams of fiber. They are also packed with powerful disease-preventing and disease-fighting vitamin C and other essential nutrients, including vitamin K and manganese.
• Raspberries are another excellent berry choice for people following a keto diet. About 10 raspberries contain 2.3 grams of carbs and 1.2 grams of fiber, which makes this serving size a great side addition to a protein and fat-packed snack. They are considered one of the healthiest fruits and are low in sugar compared to other fruits.
• Peaches are a fuzzy stone fruit considered suitable in moderation in keto diets. They contain some 15 grams of carbs and 2.25 grams of fiber per medium-sized fruit. Peaches are an excellent source of vitamins A and C, as well as boron, a mineral that contributes to bone health.
• Cantaloupe melon provides essential nutrients in a low-carb serving. One cup of diced melon is only 12.7 grams of carbs and 1.4 grams of fiber. Cantaloupe is also considered one of the best sources of the antioxidant beta-carotene, which is associated with eye health.
• Star fruit (carambola) is a star-shaped tropical fruit popular with those following a keto diet due to its particularly low-carb content. One cup of cubed star fruit contains only 8.8 grams of carbs and provides 3.7 grams of fiber. It is also a good source of vitamin C, potassium, magnesium, folate, selenium, and zinc.
• Olives are another fruit that is often overlooked. They are known for their anti-inflammatory effects and are great for heart health. One cup of olives packs about 21 grams of fat and less than one net carb. They are also a good source of sodium, which is important when following a keto diet.
• Coconut is loaded with fiber (one cup of it shredded has 7.2 grams) and is also being studied for its MCT (medium-chain triglycerides) oil content that may reduce Alzheimer's risk. A 1/2 cup of shredded coconut meat yields about 13 grams of fat and a respectable 2.5 grams of net carbs.
• Blueberries can be considered keto-friendly, but they should be consumed in moderation due to their carb content. One cup of blueberries contains about 17 grams of net carbs. They are low in sugar compared to other fruits and are a good source of fiber and antioxidants.
• Kiwis are naturally portioned and a small fruit contains only 8 to 9 grams of net carbs. They are rich in potassium and vitamin C, as well as a great source of fiber, so they do complement a ketogenic diet.
• Figs are another keto-friendly fruit that can be incorporated into sweet and savory meals. They pair well with cheese and can be a great addition to a keto charcuterie board.
• Cucumbers are technically a fruit, and they are the keto follower's best friend as they are made up of mostly water and have two grams of net carbs.

Remember, when following a keto diet, it is important to pay attention to portion sizes and your macronutrient balance. Avoid overeating high-fat foods, and be mindful of your total carb intake.
