Sweet Potatoes: Keto-Friendly Or Not?

Sweet potatoes are a nutritious food, packed with vitamins and fibre. But can you eat them on a keto diet? The keto diet is a high-fat, moderate-protein, and very low-carb diet. It is designed to induce ketosis, a metabolic state in which your body uses fat, not carbs, for energy. So, are sweet potatoes keto-approved?

Sweet potatoes are high in carbs

Sweet potatoes are a type of starchy root vegetable that is often excluded from ketogenic diets because of its naturally high carb content. A medium-sized sweet potato (100-150 grams) contains a total of 17.3-26 grams of carbs. After subtracting the 4 grams that come from fiber, you’re left with a net value of roughly 12.86-21 grams of carbs per potato.

This is a significant amount of carbs, especially for those on the keto diet, who typically limit their carb intake to 5–10% of their daily calorie needs, or a maximum of 50 grams of carbs per day. As such, consuming sweet potatoes can easily skew keto macros, the common ratio for which is 70% fat, 25% protein, and 5% carbohydrates.

However, some proponents of the keto diet say they are able to add sweet potatoes to their meal plans in very small portions, limiting consumption to 42% of their daily carb intake. Ultimately, whether you should include sweet potatoes in your diet depends on your personal carb goals and ability to consistently adhere to the restrictions required for you to maintain ketosis.

Sweet potatoes are not keto-friendly

The ketogenic diet is a high-fat, moderate-protein, and very low-carb diet. The primary goal of a ketogenic diet is to facilitate the body's transition into ketosis, a metabolic state in which the body relies on energy produced from fat, rather than carbohydrates, to function. This means that the body's ability to maintain ketosis is dependent on a lack of dietary carbohydrates.

Sweet potatoes are a type of starchy root vegetable that is often excluded from ketogenic diets because of its naturally high carbohydrate content. A medium-sized sweet potato (100-150 grams) contains 17.3-26 grams of total carbohydrates. After subtracting the fibre content, you are left with 12.86-21 grams of net carbs per potato.

Most keto dieters limit their daily carb intake to 50 grams or less, which means that a single sweet potato could easily take up almost half of their daily allowance. This is why sweet potatoes are generally avoided on keto to maintain ketosis and achieve weight loss.

While some proponents of the keto diet say they are able to add sweet potatoes to their diet in very small portions, it is important to note that this may not be feasible for everyone, especially those on a stricter keto diet. Ultimately, whether you can include sweet potatoes in your keto diet depends on your personal carb goals and your body's ability to maintain ketosis.

Sweet potatoes are healthier than white potatoes

Firstly, sweet potatoes are a good source of beta carotene, an antioxidant that protects the body's cells from damage and diseases like cancer. The body converts beta carotene into vitamin A, providing an additional health benefit.

Secondly, sweet potatoes have a lower glycemic index than white potatoes, making them a better option for people trying to keep their blood sugar down. This is because sweet potatoes have a lower carbohydrate content than white potatoes, with a medium-sized sweet potato containing 17.3 grams of total carbs, compared to 17.9 grams in a white potato of the same size.

Thirdly, sweet potatoes are rich in vitamin C, providing about one-third of the daily recommended amount. They also contain more potassium than a banana and supply about 30% of the recommended daily value of vitamin B6, which is essential for brain and nervous system health.

Finally, the key to maximising the health benefits of both types of potatoes is to eat the skin, as half of the fibre content is found there. Therefore, it is important to wash the skin thoroughly to remove any dirt before consuming.

Sweet potatoes can be included in a keto diet in small portions

Sweet potatoes are a starchy root vegetable that is often excluded from ketogenic diets due to its high carbohydrate content. A medium-sized sweet potato (100-150 grams) contains 17.3-26 grams of total carbs, which can be reduced to 12.86-21 grams of net carbs after subtracting the fibre content.

The ketogenic diet is a high-fat, moderate-protein, and very low-carb diet that aims to facilitate the body's transition into ketosis, a metabolic state where the body uses fat instead of carbohydrates for energy. To achieve ketosis, most people on a keto diet limit their daily carb intake to 5–10% of their total calorie needs, or a maximum of 50 grams of carbs per day.

Given the high carb content of sweet potatoes, they can easily push one over their daily carb limit. However, with proper planning, some people may still be able to include small portions of sweet potatoes in their keto diet. For example, if your daily carb limit is 50 grams, you could opt to spend approximately 42% of your carbs on a whole sweet potato. You can also divide a sweet potato into smaller portions to further reduce your carb intake.

Additionally, certain preparation methods may be more keto-friendly than others. Sweet potatoes prepared with high-carb ingredients like brown sugar, maple syrup, or fruit juices should be avoided. Instead, opt for higher-fat cooking methods such as frying or roasting them with butter, coconut oil, or cheese.

In conclusion, while sweet potatoes are typically not considered keto-friendly, they can be included in a keto diet in small portions, depending on your personal carb goals and ability to adhere to the restrictions required for maintaining ketosis.

Sweet potatoes are a good source of vitamins and nutrients

Sweet potatoes are a good source of beta carotene, a plant-based compound that is converted into vitamin A in the body. Vitamin A is essential for healthy vision and a well-functioning immune system. It also plays a role in maintaining healthy mucous membranes, especially in the gut lining, which is crucial as the gut is where the body is exposed to potential pathogens.

The fibre and antioxidants in sweet potatoes promote gut health. The fibre content includes both soluble and insoluble fibre, which provide various gut-related health benefits. Soluble fibre absorbs water and softens the stool, while insoluble fibre adds bulk. Both types of fibre can be fermented by gut bacteria, creating compounds that fuel the cells of the intestinal lining and support their health.

Sweet potatoes also contain unique proteins called sporamins, which are produced when the plant is damaged. These proteins account for over 80% of the vegetable's total protein content and are believed to have antioxidant properties.

The anthocyanins found in purple sweet potatoes have been linked to improved brain function in animal studies. They were found to reduce inflammation and prevent free radical damage in the brain.

While sweet potatoes are not considered keto-friendly due to their high carbohydrate content, they are a nutritious food that provides various health benefits.
