What is a healthy BMI score?

According to the World Health Organization (WHO), a healthy BMI for adults falls between 18.5 and 24.9 kg/m². A BMI below 18.5 is categorized as underweight, 25.0 to 29.9 is overweight, and 30.0 or greater indicates obesity.

How is daily calorie target (TDEE) calculated?

Total Daily Energy Expenditure (TDEE) is computed using the clinical Mifflin-St Jeor formula to determine your Basal Metabolic Rate (BMR), multiplied by your activity level factor (1.2 for sedentary up to 1.9 for very active).

When is my most fertile window during ovulation?

Your most fertile window consists of the 5 days leading up to ovulation plus the day of ovulation itself. In a standard 28-day cycle, peak ovulation occurs approximately 14 days before your next expected menstrual period.

How accurate is the Pregnancy Due Date Calculator?

Our Pregnancy Due Date Calculator applies Naegele's rule (LMP + 280 days adjusted for your average cycle length). While only ~5% of babies are born on their exact estimated due date, it establishes an accurate 37 to 42 week full-term window.
