Two things: food (calories) and oxygen.
- Food (carbohydrates, fats, and to a lesser extent protein) provides the chemical fuel — glucose, fatty acids — your cells break down for energy.
- Oxygen is needed for cellular respiration in your mitochondria to convert that fuel into ATP, the usable energy molecule.
(Water, vitamins and minerals are also important for the process, but they don’t directly provide calories.)
