Here's how to figure out how many calories to eat to lose weight using the Mifflin-St. Jeor equation, a calorie deficit calculator, or by working with an RD.
Kleiber's plot comparing body size to metabolic rate for a variety of species. [1]Kleiber's law, named after Max Kleiber for his biology work in the early 1930s, states, after many observations that, for a vast number of animals, an animal's Basal Metabolic Rate scales to the 3 ⁄ 4 power of the animal's mass.
There are also some substances, including caffeine, which can create a small (3-5%) [5] increase in caloric expenditure, via a variety of pathways that include increasing physical activity levels and increasing thermogenesis (heat output), and/or by reducing caloric input via appetite suppression.
