Percentages compare fairly between women of different sizes. Losing 5 to 10% of your body weight is a meaningful health change. Pair it with your waist and photos, because some of what you lose may be water, and muscle you build can hide fat you've lost.

Losing 5 to 10% of your body weight is widely seen as a meaningful health improvement.

The Scale & Tracking Progress
How can I track progress without the scale?
Track the changes the scale can't show: waist and body measurements, side-by-side progress photos, how your clothes fit, and whether you're lifting more than two weeks ago. Nikkiey also watches energy, sleep, cravings, recovery and habits like hitting protein and showing up to train. The scale becomes supporting data, not the decision maker.
