Cucumbers are a low-carbohydrate vegetable and therefore can be suitable for the keto diet. One cup of sliced cucumbers (approximately 119 grams) contains only 3.78 grams of carbohydrates, with 1.8 grams of fiber, which means that the net carbs (total carbs minus fiber) are only 1.98 grams.
In addition, cucumbers are high in water content and can help keep you hydrated on the keto diet, which is important because the body tends to lose water and electrolytes when in a state of ketosis.
Cucumbers are also a good source of vitamins and minerals such as vitamin K, vitamin C and potassium, which can help support overall health while on the keto diet.
Overall, cucumbers can be a great addition to a keto diet as they are low in carbohydrates, high in water content, and rich in nutrients. However, it’s essential to keep track of your total daily carbohydrate intake to ensure that you stay within the recommended limits for the keto diet.
