Fitness & Health Calculator Questions

How is BMI calculated and what do the results mean?

BMI (Body Mass Index) is calculated by dividing your weight in kilograms by your height in meters squared. Our calculator does this automatically when you enter your height and weight. Generally, a BMI under 18.5 is considered underweight, 18.5-24.9 is normal weight, 25-29.9 is overweight, and 30+ is obese. However, BMI is just one indicator of health and doesn't account for factors like muscle mass.

How accurate is the calorie calculator?

Our calorie calculator uses established formulas based on your age, gender, height, weight, and activity level to estimate your daily calorie needs. While it provides a good starting point, individual metabolism can vary. Monitor your weight over time and adjust your calorie intake accordingly.
