How It Calculates the Results

The pregnancy calorie calculator estimates the number of calories you need each day based on your age, weight, height, physical activity level, and current trimester. It uses the Mifflin-St Jeor equation for calculating the Basal Metabolic Rate (BMR), which is then adjusted for physical activity level and pregnancy demands. Here is the formula it uses:

• BMR = 10 * weight (kg) + 6.25 * height (cm) – 5 * age (years) + 5 (for males, females use -161)
• Activity Adjustment: Sedentary = BMR * 1.2, Light = BMR * 1.375, Moderate = BMR * 1.55, Active = BMR * 1.725
• Trimester Adjustment: 1st Trimester = 0 extra calories, 2nd Trimester = +300 calories, 3rd Trimester = +450 calories

The final calorie needs per day are provided after adjusting for these factors.
