The Calculadora de Calorias Harris Benedict, based on the Harris-Benedict equation, is a handy tool to estimate your daily calorie requirements. By taking into account your gender, weight, height, age, and activity level, this calculator provides you with a personalized estimate of your daily caloric needs.
Formula
The Harris-Benedict equation, used by this calculator, takes different parameters into account for men and women. For men:
BMR = 88.362 + (13.397 * weight in kg) + (4.799 * height in cm) – (5.677 * age in years)
For women:
BMR = 447.593 + (9.247 * weight in kg) + (3.098 * height in cm) – (4.330 * age in years)
Once the Basal Metabolic Rate (BMR) is calculated, it is multiplied by an activity factor to estimate daily calorie needs:
- Sedentary (little or no exercise): BMR * 1.2
- Lightly active (light exercise or sports 1-3 days a week): BMR * 1.375
- Moderately active (moderate exercise or sports 3-5 days a week): BMR * 1.55
- Very active (hard exercise or sports 6-7 days a week): BMR * 1.725
How to Use
- Select your gender.
- Enter your weight in kilograms.
- Input your height in centimeters.
- Provide your age in years.
- Choose your activity level from the dropdown.
- Click the “Calcular” (Calculate) button.
- Your estimated daily caloric needs will be displayed.
Example
Suppose you are a 30-year-old female, weighing 60 kg, with a height of 160 cm, and you engage in moderate exercise. The calculator estimates your daily caloric needs to be approximately 1680 Kcal.
FAQs
- What is the Harris-Benedict equation? The Harris-Benedict equation is a formula used to calculate the Basal Metabolic Rate (BMR), which represents the number of calories your body needs at rest.
- How do I choose my activity level? Your activity level depends on your daily physical activities. If you’re unsure, select the option that best describes your typical daily routine.
- Why is gender a factor in the equation? Men and women have different BMR formulas because they generally have different body compositions and metabolic rates.
- Can this calculator help with weight management? Yes, by knowing your daily calorie needs, you can better plan your diet and understand your calorie intake.
- Is this calculator suitable for athletes? It can provide an estimate, but for athletes with very high activity levels, a more precise calculation may be necessary.
