BMR calculator:

A BMR (Basal Metabolic Rate) calculator is an application that helps you estimate the bundle of calories your body requires to perform essential functions while at rest. These basic functions include things like breathing, circulating blood, regulating body temperature, and maintaining organ functions. In simple terms, it's the amount of energy your body requires to stay alive without doing any physical activity. A BMR calculator takes into account factors like your age, gender, weight, and height to provide you with an estimate of your BMR. Knowing your BMR is helpful because it serves as a starting point to determine your daily calorie needs.

To calculate your BMR, there are different formulas available, but a common one is the Mifflin-St Jeor Equation. This formula takes into account your age, weight, height, and gender. Keep in mind that BMR is individual, and it varies from person to person. If you want to customize your BMR calculations, consider other factors like muscle mass, activity level, and health conditions. For instance, if you have more muscle, your BMR might be higher because muscle burns more calories than fat. Also, if you are very active, your BMR will be higher since you burn more calories throughout the day.
