How to use them together
- Start with BMI to see whether your current weight sits in the WHO healthy range for your height and to set a realistic goal weight.
- Run the TDEE calculator to estimate how many calories you burn on a normal day, then subtract 300–500 kcal for a beginner-safe deficit.
- Split that target with the macro calculator so you know how many grams of protein, carbs, and fat to aim for — protein is the one that matters most for preserving muscle while you lose.
- Project the finish line with the timeline calculator so you know roughly how many weeks the plan will take and what a realistic weekly rate looks like.
