TDEE explained
Total Daily Energy Expenditure is everything you burn in 24 hours: your resting metabolism plus the energy of moving, exercising, and digesting food. It's the number that determines whether you lose, hold, or gain weight. Eating below your TDEE creates a deficit; eating above it, a surplus.
