![]() ![]() ![]() Polysaccharides such as cellulose cannot be easily metabolized by many organisms, including humans, but can still provide them with valuable dietary fibers, which helps with digestion. Glucose is a monosaccharide and is one of the key sources of energy for humans, as well as other animals. Monosaccharides and disaccharides are often referred to as "simple carbohydrates," while oligosaccharides and polysaccharides are referred to as "complex carbohydrates." Carbohydrates are often also classified based on the number of saccharides that comprise them: monosaccharides, disaccharides, oligosaccharides, and polysaccharides. Sugar is the simplest form of carbohydrate, while starch and fiber are complex carbohydrates. Processed meats (deli meats, sausages, fast-food burgers etc.)Ĭarbohydrates, often referred to as simply "carbs," are compounds that are typically classified as sugar, starch, or fiber.There are also healthier and unhealthier proteins. Although protein is a necessary part of the human diet, as with most things, moderation is important. There also exist protein supplements that are sometimes used by people who are trying to build muscle. There are numerous sources of protein, both animal (meat, dairy, etc.) and plant-based (beans, legumes, nuts, seeds, etc.). These amino acids are typically referred to as "essential amino acids," and are obtained by humans and other animals through the consumption of protein. Amino acids are essential to a person's well-being, and there are certain amino acids that can only be obtained through diet. Proteins are organic compounds comprised of amino acids, and are one of the types of macronutrients. While macronutrients are necessary daily in amounts on the order of grams, humans typically only need fewer than 100 milligrams of micronutrients each day. Micronutrients are another essential part of human nutrition and consist of vitamins and dietary minerals such as Vitamin A, copper, iron, and iodine. In this calculator, we only calculate daily carbohydrate, protein, and fat needs. Some definitions also include water, air, calcium, sodium, chloride ions, and some other substances, along with more typical macronutrients, since they are needed in large quantities by the human body. Specifically, they refer to carbohydrates, proteins, and fats. 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.

The Katch-McArdle Formula is slightly different in that it calculates resting daily energy expenditure (RDEE), which takes lean body mass into account, something that neither the Mifflin-St Jeor nor the Harris-Benedict Equation do. The Mifflin-St Jeor Equation also calculates BMR, and has been shown to be more accurate than the revised Harris-Benedict Equation. It was revised in 1984 to be more accurate and was used up until 1990, when the Mifflin-St Jeor Equation was introduced. The Harris-Benedict Equation was one of the earliest equations used to calculate basal metabolic rate (BMR), which is the amount of energy expended per day at rest. This Calorie Calculator is based on several equations, and the results of the calculator are based on an estimated average. ![]()
