Some vegetables to avoid on keto

There’s a lot of misinformation when it comes to the ketogenic diet. Many people believe that it’s all bacon and butter and avoiding fruits and veggies, but that’s completely untrue. Vegetables play a key role in a well-formulated ketogenic diet! That being said, not all veggies are created equal and some should be avoided. So, here are the top vegetables to avoid on keto!

1. Corn

Corn is a staple starchy vegetable in many different food products (including cereal). Whether consumed alone or as part of a pre-packaged food product, corn is high in carbohydrates and can spike your blood glucose levels. One cup of corn contains 177 calories, 41g of carbohydrates, 4.6g of fiber, 2.1g of fat, and 5.4g of protein. [1]

2. Carrots

Carrots tend to be a diet-food staple, but they are relatively high in sugar (as compared to other vegetables). 100g of carrots (about 10 baby carrots) contain 35 calories, 8.2g of carbohydrates, 2.9g of fiber, 0.1g of fat, and 0.6g of protein. [2]

3. Peas

Whether you enjoy green peas as a side dish or in carbonara, they tend to have a higher carbohydrate count as compared to other green vegetables and should be avoided on keto. 1/2 cup (85g) of unsalted peas contains about 59 calories, 10.7g of carbohydrates, 3.5g of fiber, 0.3g of fat, and 3.8g of protein. [3]

4. Potatoes

Potatoes are a staple starchy vegetable in most American diets. Whether you enjoy mashed potatoes, french fries, tater tots, or just roasted potatoes, you likely know that they aren’t exactly the healthiest. Potatoes are definitely a big no-no on the ketogenic since they are one of the highest carb veggies. 1 Russet potato contains about 290 calories, 64.1g of carbohydrates, 6.9g of fiber, 0.4g of fat, and 7.9g of protein. [4]

5. Sweet Potatoes

Sweet potatoes are often seen as a healthy alternative to traditional white potatoes. While sweet potatoes digest slower and have a lower glycemic index, as compared to traditional white potatoes, they still have a high carb count. One sweet potato (~113g) contains approximately 112 calories,26.2g of carbs, 0.1g of fat, 0.2g of protein. [5]
