Basal metabolic rate
ChatGPT’s explanation of “Basal Metabolic Rate”: Basal metabolic rate refers to the minimum energy consumption required by the human body to maintain basic physiological functions in a quiet state. This energy consumption is mainly used to support heart beating, breathing, body temperature regulation and other basic life activities. Basal metabolic rate is usually expressed in calories (kcal) and is affected by many factors, including age, gender, weight, height and muscle mass.
For example, a young man who weighs 70 kilograms and is 175 centimeters tall may have a basal metabolic rate of about 1700 calories, which means that he needs to consume 1700 calories a day at rest to maintain basic physiological functions.
There are many formulas for calculating basal metabolic rate, one of which is the Harris-Benedikt formula. This formula estimates basal metabolic rate based on gender, age, weight, and height.
The concept of basal metabolic rate originated in the early 20th century. With the development of physiology and nutrition, scientists began to study different aspects of human energy consumption and proposed this important indicator. Understanding your basal metabolic rate is important when planning your diet and exercise plans because it helps people understand how much energy they need each day to achieve their weight loss or weight gain goals.
