About this calculator
The GETB近似 calculator estimates basal metabolic rate (BMR) using a simplified formula: 10 × weight (kg) + 2500 for men or 2000 for women. This quick calculation helps understand energy needed for vital functions at rest, such as breathing and circulation. While less accurate than formulas like Mifflin-St Jeor or Harris-Benedict, it's suitable for daily estimates.
Use this tool to plan diets, monitor metabolism, or understand how weight affects calorie needs. For example, a 70 kg man would have BMR ≈ 10×70 + 2500 = 3200 calories/day. A 60 kg woman would have ≈ 10×60 + 2000 = 2600 calories/day. Results may vary with age, height, body composition, and physical activity.
Avoid using this calculator for medical or diagnostic purposes. The formula ignores factors like height, age, and body type, making it less suitable for athletes, elderly individuals, or those with nutritional imbalances. For greater accuracy, consult a nutritionist or use methods with more variables.
Frequently asked questions
Why is the GETB近似 formula simpler than others?
The formula was simplified for quick calculations, ignoring variables like age, height, and body composition. It's suitable for general estimates, not medical precision.
Can I use this calculator for athletes?
Not recommended, as it doesn't account for high muscle mass common in athletes. Use methods that include height and age for better accuracy.
How to adjust the result for physical activity?
Multiply BMR by an activity factor (1.2 for sedentary up to 2.4 for intense training). Example: 3200 × 1.55 = 4960 calories/day.
What is the calculator's accuracy?
The estimate can have ±15% error compared to more complete methods. It's useful for initial guidance but doesn't replace professional consultation.
