What is the Mifflin-St. Jeor Equation?

The Mifflin-St. Jeor equation is a widely respected method for calculating Basal Metabolic Rate (BMR), which represents the number of calories your body needs at rest to maintain vital functions such as breathing and digestion. This formula is considered more accurate than older methods and is highly recommended by nutrition and health professionals.

The level of human activity is usually distinguished by five degrees of physical activity per day:

• 1.2 – minimal activity, sedentary work that does not require significant physical exertion;
• 1.375 – light activity level: intense exercise for at least 20 minutes one to three times a week. This could be cycling, jogging, basketball, swimming, skating, etc. If you do not exercise regularly but maintain a busy lifestyle that requires frequent walking for long periods of time, then choose this ratio;
• 1.55 – moderate level of activity: intense training for at least 30-60 minutes three to four times a week (any of the sports listed above);
• 1.7 – heavy or labor-intensive activity: intense exercise and sports 5-7 days a week. Labor-intensive occupations are also suitable for this level and include construction work (brickwork, carpentry, etc.), agricultural employment, etc.;
• 1.9 – extreme level: includes extremely active and/or very energy-consuming activities: sports with an almost daily schedule and several workouts during the day; very labor-intensive work, such as shoveling coal or working long hours on an assembly line. This level of activity is often very difficult to achieve.
