Carbohydrates, or carbs, are the source of energy for the body. The body converts carbs into sugar in the bloodstream, providing energy for all activities. Some foods contain carbohydrates, while others are carb-free.
Foods that contain carbohydrates are often plant-based. The photosynthesis process allows plants to store energy as sugar, which is a carbohydrate.
Fibre is a carbohydrate, but it has no effect on blood sugar levels. Insoluble fibre is not digested by the body.
A net carb is calculated by subtracting insoluble fibre grams from the total amount of carbohydrate in a food. Some foods, such as flax, are so high in fibre and oil that calculating net carbs makes them a carb-free food.
Meat from any source contains no carbohydrates at all.
There are many sweeteners on the market that contain no carbohydrates. Erithrytol, sucralose, and stevia are all carb-free substances.
