BMR – Definition & Meaning

BMR is a term that is often used in the field of nutrition, fitness, and health. It is an acronym that stands for Basal Metabolic Rate. This term is used to describe the number of calories that a person burns while at rest. Understanding BMR is essential for people who are trying to lose weight, maintain a healthy weight, or improve their overall health.


BMR is defined as the number of calories that a person burns while at rest. This means that the body is not doing any physical activity, and the person is in a state of complete rest. BMR is often used as a baseline for calculating the number of calories that a person needs to consume to maintain their weight.


The concept of BMR has been around for centuries. It was first introduced by a French chemist named Antoine Lavoisier in the late 18th century. Lavoisier discovered that the human body produces heat, and this heat is a result of the body’s metabolism. He also discovered that the amount of heat produced by the body is directly related to the amount of oxygen consumed.
