Choose an illustrative weekly pace

Paces are examples—not prescriptions. Each percentage applies to the remaining current weight in each modeled week, so the illustrative weekly amount gradually decreases.

Optional: add your height to check BMI context

If supplied, we’ll flag goals below the standard adult BMI 18.5 reference threshold. BMI has important limitations.
