Frequently asked questions
Why no target date or kilograms?
Weight response changes with metabolism and activity; a fixed calorie-to-kilogram rule is unreliable.
Is 300 a recommendation for me?
No. It is an editable example. Seek clinical advice for unexplained weight loss, pregnancy or illness.
Is this medical advice?
For reference only; it does not replace a clinician.
