What are carbs?

Carbohydrates are one of the three major groups of nutrients that provide calories; the other two are protein and fat. Every food that comes from plants contains carbohydrates, because carbs are originally a plant's own food source! Carbs are made of three elements: carbon, hydrogen and oxygen. That's why they're called carbohydrates: "carbo" refers to carbon, and "hydrate" to water, a combination of hydrogen and oxygen. Each gram of carbohydrate by weight provides four calories of energy.
