Frequently asked questions
Why does loss slow down?
A lighter body burns fewer calories, so the same intake produces a smaller deficit. Recalculate every 10 lb.
What is a sustainable rate?
0.5–1% of body weight per week keeps most muscle and is far easier to maintain than crash dieting.
What do I need to enter into the Goal Weight Date Calculator?
