Popular Health & Fitness Multi‑Calculator Explained
BMI Calculator (Body Mass Index)
According to the World Health Organization (WHO), the BMI calculator is one of the most widely used health tools. It estimates whether a person’s weight is healthy based on their height.
How BMI Works: BMI is calculated by dividing weight (kg) by height (m²). The result falls into categories such as underweight, normal weight, overweight, or obese.
Why BMI Is Useful:
- Simple and quick health screening
- Helps identify weight‑related health risks
- Commonly used by doctors and fitness experts
Limitations: BMI does not measure muscle mass or fat distribution, so it should be used as a general guideline rather than a medical diagnosis.
Daily Calorie Needs Calculator
A calorie calculator estimates how many calories your body needs per day to maintain, lose, or gain weight.

Key Concepts Behind It:

Benefits:
- Supports weight management goals
- Helps plan balanced meals
- Prevents overeating or undereating

Hydration is often overlooked, yet it is essential for skin health, digestion, energy levels, and overall wellness.

- Improves physical performance
