Calorie target calculator
We start from TDEE, then adjust using the ~3,500 kcal per lb rule of thumb. Aggressive deficits are harder to sustain; slower changes are often healthier.

TDEE across activity levels (same inputs)
Reference curve for how activity multipliers scale energy needs before applying your weight-goal adjustment. Educational illustration only — not a diagnosis or personal target.
TDEE from Mifflin–St Jeor + standard activity factors; deficit heuristic from common energy-balance teaching tools.
Sources, formulas & further reading
Based on: Mifflin–St Jeor TDEE with a common ~3,500 kcal/lb weekly energy-balance heuristic.
