Macro Calculator

In the context of health and fitness, macronutrients are most often defined to be the chemical compounds that humans consume in large quantities that provide bulk energy. Specifically, they refer to carbohydrates, proteins, and fats.

The number of calories a person needs to consume on a daily basis is mainly based on a number of factors including height, weight, age, and activity level, along with whether the person wants to maintain, lose, or gain weight.

Proteins are organic compounds comprised of amino acids, and are one of the types of macronutrients.

Carbohydrates, often referred to as simply "carbs," are compounds that are typically classified as sugar, starch, or fiber.

Fats are molecules that are comprised primarily of carbon and hydrogen atoms. Common examples include cholesterol, phospholipids, and triglycerides.
