Weight Loss Calculator

Achieving a healthy weight is one of the most common fitness goals worldwide, but it often requires careful planning and consistent tracking. The Weight Loss Calculator is a smart, user-friendly tool designed to help individuals estimate how long it will take to reach their target weight, how many calories they need daily, and whether their current weight falls within a healthy range.

By combining key health metrics like BMI, BMR, activity level, and weight goals, this tool provides a personalized roadmap for weight management.
