Weight Loss Visualizer – Addition.site
A free, web‑based tool that lets you plot, track, and share your weight‑loss journey in seconds.

How It Works

Choose a Unit – Pick kg or lbs from the drop‑down. The weight field will automatically convert to the selected unit.
Enter Your Starting Data
Start weight – Your current weight.
Start BMI – Your current Body Mass Index.
Start date – When you began your plan.
Set Your Goal
End date – When you expect to reach your target.
Target BMI – The BMI you’re aiming for.
Click “visualize” – The script draws a line chart (powered by Chart.js) that shows how your weight should change day‑by‑day to hit that BMI by the end date.
View the Result – The “result” field displays the projected weight at your target BMI. Click it to copy the value to your clipboard.
Share on X (formerly Twitter) – Hit the “𝕏” button to open a share dialog with a link to your graph.

What Is BMI?

BMI (Body Mass Index) = weight (kg) ÷ height² (m²).
It’s a quick, widely used screening tool for categorizing underweight, normal, overweight, and obesity.
While BMI doesn’t account for muscle mass or body composition, it’s a helpful baseline for setting realistic weight‑loss goals.

Clarity – See exactly how many kilos (or pounds) you need to lose each week.
Motivation – A visual timeline keeps you focused on the big picture.
Planning – Adjust your end date or target BMI to find a realistic pace.
Sharing – Share your progress with friends, trainers, or on social media to stay accountable.
