Energy & macros

Ideal / healthy body-weight range

Estimated ideal body weight from height and sex via four classic clinical formulas (Devine, Robinson, Miller, Hamwi), plus the healthy-BMI (18.5–24.9) weight band and your current BMI for context. Adult equations: ages 18 to 120. A younger age returns 400; for a child or teenager use myplate-plan or dri, whose energy equations have child forms. Above the healthy-BMI band, ideal_weight also carries firstGoal (the weights 5 to 10% under the current weight, the first goal in the 2013 AHA/ACC/TOS obesity guideline) and adjusted (the Hamwi ideal weight plus 25% of the weight above it). Both are null at or under the band, and in pregnancy and while breastfeeding. weight_loss_withheld gives the reason when they are withheld (pregnancy or lactation).
