Which one do I need?
Start with the TDEE calculator. It gives you the one figure everything else is built on: how many calories your body burns in an average day.
If you want to lose weight, take that number to the calorie deficit calculator to choose a pace you can actually hold and see how long it will take.
Once the calorie target is set, the macro calculator splits it into daily grams of protein, carbs, and fat — and the calorie database tells you what that looks like on a plate.
