Your TDEE (Total Daily Energy Expenditure) is the total number of calories your body burns in a day, combining your Basal Metabolic Rate with your physical activity.

TDEE & the Australian Movement Guidelines
The Australian 24-Hour Movement Guidelines (Department of Health) recommend adults accumulate 150–300 minutes of moderate or 75–150 minutes of vigorous activity per week, plus muscle-strengthening on 2+ days. Your activity multiplier in this calculator reflects how closely you meet these guidelines — most Aussies sit in the "lightly active" band according to ABS data.
