Reverse Diet Calculator
Ease calories back up toward maintenance.
How it’s calculated
Maintenance comes from Mifflin–St Jeor × activity; the tool shows the gap from your current intake and a weekly step to close it.
Gap = TDEE − current intake. Suggested step ≈ +100 kcal/week until you reach maintenance.
Source: Mifflin–St Jeor (1990); reverse-dieting is a practical, not clinically standardised, approach.
