Ideal weight calculator (Hamwi, Devine, Robinson)
Compare three clinical ideal-weight formulas from height, then set a realistic GLP-1 goal with your clinician.
Ideal weight (Hamwi / Devine / Robinson / Miller)
Compare four clinical height formulas, then use the BMI healthy band as context. GLP-1 goals are usually percent loss from your start weight, not a chart number.
