How to Use the Pigly Weight Loss Calculator
Using the calculator is simple and beginner-friendly.
Step 1: Select Gender
Choose either:
- Male
- Female
Gender affects Basal Metabolic Rate (BMR) calculations.
Step 2: Enter Your Age
Input your current age in years.
Age influences metabolism and calorie requirements.
Step 3: Enter Height
Provide your height in centimeters.
The calculator uses height for BMI and calorie calculations.
Step 4: Enter Current Weight
Input your present body weight in kilograms.
Step 5: Enter Target Weight
Add the weight you want to achieve.
The target weight must be lower than the current weight.
Step 6: Choose Activity Level
Select your daily activity category:
| Activity Level | Description |
|---|---|
| Sedentary | Little or no exercise |
| Lightly Active | Light exercise 1–3 days/week |
| Moderately Active | Moderate exercise 3–5 days/week |
| Very Active | Intense exercise regularly |
Step 7: Click Calculate
The calculator instantly displays:
- BMI
- Daily calorie needs
- Total weight to lose
- Estimated weeks required
Understanding BMI (Body Mass Index)
BMI is a common measurement used to evaluate body weight relative to height.
BMI Formula
BMI=Height (m)2Weight (kg)
BMI Categories
| BMI Range | Category |
|---|---|
| Below 18.5 | Underweight |
| 18.5 – 24.9 | Normal Weight |
| 25 – 29.9 | Overweight |
| 30+ | Obese |
BMI helps users understand their current health status.
Understanding Basal Metabolic Rate (BMR)
BMR represents the number of calories your body burns while resting.
The calculator uses the Mifflin-St Jeor Equation.
BMR Formula for Men
BMR=10W+6.25H−5A+5
BMR Formula for Women
BMR=10W+6.25H−5A−161
Where:
- W = Weight in kilograms
- H = Height in centimeters
- A = Age in years
Maintenance Calories Formula
Maintenance calories estimate how many calories you need daily to maintain your current weight.
Formula
Maintenance Calories=BMR×Activity Level
Weight Loss Timeline Formula
The calculator assumes a healthy weight loss pace of approximately 0.5 kg per week.
Formula
Weeks=0.5Weight to Lose
This provides a realistic and sustainable timeline.
Example Weight Loss Calculation
Let’s look at a practical example.
User Information
| Metric | Value |
|---|---|
| Gender | Male |
| Age | 30 |
| Height | 175 cm |
| Current Weight | 90 kg |
| Target Weight | 75 kg |
| Activity Level | Moderately Active |
Step 1: Calculate BMI
Height in meters:
175 cm = 1.75 m
BMI:
90 ÷ (1.75 × 1.75) = 29.4
Result:
BMI = 29.4
This falls into the overweight category.
Step 2: Calculate BMR
BMR:
(10 × 90) + (6.25 × 175) − (5 × 30) + 5
= 900 + 1093.75 − 150 + 5
= 1848.75
Step 3: Maintenance Calories
1848.75 × 1.55 = 2865 kcal
Result:
Maintenance Calories = 2865 kcal/day
Step 4: Weight to Lose
90 − 75 = 15 kg
Step 5: Estimated Timeline
15 ÷ 0.5 = 30 weeks
Result:
Estimated Time = 30 weeks
Why Healthy Weight Loss Matters
Crash dieting may seem attractive, but rapid weight loss often leads to:
- Muscle loss
- Nutrient deficiencies
- Slower metabolism
- Fatigue
- Weight regain
The calculator promotes gradual and safer progress.
Best Practices for Successful Weight Loss
