GLP-1 medication: how to read your weight curve

On a GLP-1 medication such as semaglutide or tirzepatide, weight rarely drops evenly: flat weeks and sudden drops alternate, and the pace can change after a dose change. Daily readings keep fluctuating with water, salt and digestion. What tells you more is the weekly rate of your trend weight per dose step, not the difference between two weigh-ins.
