What does energy balance mean in the body?

Energy in from food equals the energy your body uses.

Body mass increases; extra energy is stored, mostly as fat.

Body mass decreases; the body uses stored fat and glycogen for energy.

Respiration in cells releases energy.

To contract muscles, keep warm, and build large molecules like proteins.

It increases energy use; without extra food, this creates an energy deficit.

The speed of chemical reactions in the body; a higher rate uses more energy.

More exercise and more muscle or body mass.

Joules (J), often kilojoules (kJ).

Energy in (kJ eaten) minus energy out (kJ used); positive means gain, negative means loss.
