Answer: Cucumbers are an extremely keto-friendly vegetable at under 2 g of net carbs per serving.
Cucumbers are low in calories and low on the glycemic index. At just 1.6 g of net carbs in a 1/2 cup serving, they're happily low in carbohydrates.
Cucumbers are also rich in vitamins and minerals. They contain antioxidants to fight free radicals, which are unstable atoms that damage cells. 96% of a cucumber is water, which also makes them a great way to stay hydrated.
Use cucumbers liberally in your salads or as a snack.
