Health calculator FAQs

What is a healthy BMI range?

BMI categories are: underweight below 18.5, normal weight from 18.5 to 24.9, overweight from 25 to 29.9, and obese at 30 or above. BMI is a screening estimate, not a full medical assessment.

How many calories should I eat daily?

Daily calorie needs depend on age, gender, weight, height, and activity level. The calorie calculator estimates BMR and then adjusts it by activity level.

How much water should I drink daily?

A common target is around 2 liters, but weight, climate, and activity change the number. Use the water intake calculator for a personal estimate.

What are macronutrients?

Macronutrients are carbohydrates, proteins, and fats. A balanced plan changes by goal, but the nutrition tracker helps you compare intake against daily needs.

How accurate is the pregnancy due date calculator?

It estimates a due date from the last menstrual period and cycle length. Confirm dates and any health decision with your doctor.
