How the Fitness Calculator works
1. Input Parameters
- Units: Choose between metric (kg, cm) and imperial (lbs, ft, in) units to input your measurements accurately.
- Age: Your age is an essential factor because metabolic rate generally decreases with age.
- Gender: Men and women have different basal metabolic rates (BMR), which is why we ask for your gender to apply the correct formula.
- Current Weight: Knowing your current weight allows the calculator to determine your BMR accurately. Input can be in kilograms (kg) or pounds (lbs) based on your unit selection.
- Preferred End Weight: This is your target weight. By considering the difference between your current weight and preferred end weight, the calculator can tailor your caloric needs.
- Height: Enter your height in either centimeters or feet and inches. This allows the calculator to include this important factor in the BMR calculation.
- Activity Level: Your daily activity level significantly affects your caloric needs. Choose from sedentary, lightly active, moderately active, very active, or super active to reflect your lifestyle.
- Goal: Select whether you want to lose weight or gain weight. This helps the calculator adjust your caloric intake accordingly.
2. Calculation Process
The Fitness Calculator uses the Mifflin-St Jeor Equation, a highly regarded method for estimating BMR, which is the number of calories your body needs at rest to maintain its current weight.
For Men: BMR=10×weight (kg)+6.25×height (cm)−5×age (years)+5\text{BMR} = 10 \times \text{weight (kg)} + 6.25 \times \text{height (cm)} – 5 \times \text{age (years)} + 5BMR=10×weight (kg)+6.25×height (cm)−5×age (years)+5
For Women: BMR=10×weight (kg)+6.25×height (cm)−5×age (years)−161\text{BMR} = 10 \times \text{weight (kg)} + 6.25 \times \text{height (cm)} – 5 \times \text{age (years)} – 161BMR=10×weight (kg)+6.25×height (cm)−5×age (years)−161
After calculating the BMR, we multiply it by an activity factor based on your selected activity level:
- Sedentary (little or no exercise): BMR×1.2\text{BMR} \times 1.2BMR×1.2
- Lightly active (light exercise/sports 1-3 days/week): BMR×1.375\text{BMR} \times 1.375BMR×1.375
- Moderately active (moderate exercise/sports 3-5 days/week): BMR×1.55\text{BMR} \times 1.55BMR×1.55
- Very active (hard exercise/sports 6-7 days/week): BMR×1.725\text{BMR} \times 1.725BMR×1.725
- Super active (very hard exercise/sports & physical job): BMR×1.9\text{BMR} \times 1.9BMR×1.9
3. Adjusting for Goals
- Weight Loss: If your goal is to lose weight, the calculator will reduce your daily caloric intake by 500 calories to create a caloric deficit.
- Weight Gain: If you aim to gain weight, the calculator increases your daily caloric intake by 500 calories to create a caloric surplus.
