Realistic Weight Loss Calculator

Weight loss can often feel confusing, especially when trying to balance calories, activity levels, and realistic timelines. The Realistic Weight Loss Calculator simplifies this process by giving users a complete, science-based estimate of how long it may take to reach their goal weight. It also calculates BMI, daily calorie needs, and a healthy weight range based on personal details.

This tool is designed for anyone who wants a structured, data-driven approach to weight loss instead of guesswork or extreme dieting.
