Calorie-deficit tiers for weight loss

Maintenance calories (TDEE) and up to three deficit tiers — mild (−250), standard (−500) and aggressive (−750 kcal/day) — with the realistic weekly rate each buys and a flag when a target dips below BMR. 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. weight_loss_targets lists only the paces myplate.food itself offers: a pace whose target is under 1,200 kcal a day for women or 1,500 for men (the low end of the calorie prescriptions in the 2013 AHA/ACC/TOS obesity guideline) is left out and named, without a figure, in weight_loss_not_offered. weight_loss_default is the pace the calculator page opens on and weight_loss_floor_kcal is the floor that was applied. In pregnancy and while breastfeeding no targets are returned, and weight_loss_withheld gives the reason (pregnancy or lactation).
