MET (metabolic equivalent) compares an activity’s energy use with sitting still. A 70 kg person walking at 3 mph (3.5 MET) burns about 245 kcal an hour, so one 240 kcal glazed donut takes about an hour of walking.

What each result means
- Time to burn it off = [Calories eaten]÷[Calories burned per hour]
- Equivalent walking steps (approx.) = [Calories eaten]÷0.04
Formula
Calories burned per hour = MET × body weight (kg)
Time to burn = calories eaten ÷ (MET × weight)
Worked example
Inputs — Donut: Glazed yeast donut (Dunkin' Glazed); Number eaten: 1; Activity: Walking, 3 mph; Your body weight: 70 kg.
Results — Calories eaten = 240 kcal; Calories burned per hour = 245 kcal; Time to burn it off = 0 h 59 min; Equivalent walking steps (approx.) = 6,000.
