The 21 Best Low-Carb Veggies, Part One

Vegetables are low in calories but rich in vitamins, minerals and other important nutrients.

In addition, many are low in carbs and high in fiber, making them ideal for low-carb diets.

The definition of a low-carb diet varies widely. Most are under 150 grams of carbs per day, and some go as low as 20 grams per day.

Whether you’re on a low-carb diet or not, eating more vegetables is always a great idea.
