This list includes 16 of the best low carb vegetables, most with less than 8 go of net carbs in a serving.

Veggies and healthy eating go hand in hand, and keto is no exception to this rule. But on a keto diet, you need to pay close attention to carbs in vegetables to stay within your daily limits.

Unfortunately, there’s no standard definition of low-carb vegetables, which makes searching for truly low-carb options difficult. As a general rule, those with less than 8 g of net carbs in a serving can be said to fit this definition (the USDA sets the serving size of most fruit and vegetables at one cup).

Now you’re wondering, “what vegetables are low-carb and what vegetables can I eat on a keto diet?”

To find out, take a look at this list of the 16 best low-carb vegetables for your keto diet.
