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.
To lose one pound of body weight, you typically need to create a calorie deficit of roughly 3,500 calories. This can be achieved through reducing calorie intake, increasing physical activity or both.
The Harris–Benedict equation (also called the Harris-Benedict principle) is a method used to estimate an individual's basal metabolic rate (BMR).. The estimated BMR value may be multiplied by a number that corresponds to the individual's activity level; the resulting number is the approximate daily kilocalorie intake to maintain current body weight.
(For example, if the calculator determines your calorie goal is 2000 calories, subtracting 10% or 200 calories would give you a goal of 1800 calories per day for weight loss.)
A caloric deficit (also known as calorie deficit, in British English calorific deficit) is any shortage in the number of calories consumed relative to the number of calories needed for maintenance of current body weight (energy homeostasis).
The Estimated Energy Requirement, , is the estimated number of daily kilocalories, or Calories, an individual requires in order to maintain his or her current weight. For a person with a body mass of m {\displaystyle m} (kg), height of h {\displaystyle h} (m), age of a {\displaystyle a} (years) and Physical Activity PA {\displaystyle {\text{PA ...
