Daily Energy Expenditure
Estimate adult resting energy and apply an explicitly entered activity multiplier.
Pre-filled values are examples, not personal facts or current local rates. Replace them before calculating.
Calculation method and references
REE = 10 × kg + 6.25 × cm ? 5 × age + sex constant (+5 male, ?161 female); daily estimate = REE × entered activity multiplier.
