Do these health calculators replace medical advice?
No. They give indicative benchmarks (BMI, calorie needs, hydration, sleep) but do not replace advice from a healthcare professional, especially in specific situations.
Which tool should I use to estimate my daily calorie needs?
The calorie calculator, based on the Mifflin-St Jeor formula, estimates your basal metabolism and calorie needs based on your activity level and goal (maintain, lose, gain).
