What Are Low-Carb Vegetables?
Low-carb veggies are generally low in total carbohydrates, plus high in fiber.
Fiber is a nutrient that moves slowly through the gastrointestinal tract and remains undigested.
Although the amount of fiber is technically included in the total carb count of a food, it doesn’t impact blood sugar levels, hunger or appetite the same way as most carbs.
Therefore, foods with a higher amount of fiber tend to have a lower number of net carbs, which is calculated by subtracting the grams of fiber from the total grams of carbohydrates.
So what vegetables are high in carbs? And what are the lowest carb vegetables and fruits?
