Calcular Peso Basal

What is Basal Metabolic Rate (BMR)?

The Basal Metabolic Rate (BMR) is the amount of energy your body needs to perform essential functions while at complete rest. These functions include breathing, circulation, and maintaining body temperature. BMR is a key factor in determining your Total Daily Energy Expenditure (TDEE), which accounts for all physical activity throughout the day.

Understanding your BMR helps in making informed decisions about nutrition and exercise. For example, if you know your BMR, you can calculate how many calories you need to maintain, lose, or gain weight. It's also useful for athletes and individuals with specific health conditions who need to monitor their energy intake.

BMR Formula

The most commonly used formula for calculating BMR is the Mifflin-St Jeor Equation, which is considered more accurate than older formulas like the Harris-Benedict Equation. The formula takes into account your weight, height, age, and gender.

This formula provides an estimate of your BMR based on your physical characteristics. It's important to note that individual variations can occur, and factors like muscle mass, body composition, and genetics can influence your actual BMR.

How to Use This Calculator

Using our BMR calculator is simple and straightforward. Follow these steps to get your personalized BMR:

1. Enter your weight in kilograms or pounds.
2. Enter your height in centimeters or inches.
3. Enter your age in years.
4. Select your gender (male or female).
5. Click the "Calculate" button to get your BMR.

The calculator will display your BMR in calories per day. You can also see a visual representation of your BMR compared to the average for your age and gender.

How to Interpret Your Results

Once you have your BMR, you can use it to estimate your Total Daily Energy Expenditure (TDEE) by multiplying your BMR by an activity factor. The activity factors are as follows:

• Sedentary (little or no exercise): BMR × 1.2
• Lightly active (light exercise/sports 1-3 days/week): BMR × 1.375
• Moderately active (moderate exercise/sports 3-5 days/week): BMR × 1.55
• Very active (hard exercise/sports 6-7 days a week): BMR × 1.725
• Athlete (very hard exercise/sports & physical job): BMR × 1.9

Understanding your TDEE helps you determine how many calories you need to consume each day to maintain, lose, or gain weight. For example, if you want to lose weight, you might need to consume 300-500 calories fewer than your TDEE each day.
