Every calorie of energy in your body originated in a star. Not metaphorically. Thermodynamically.

The food you eat - whether plant or animal - derives its energy from photosynthesis, the process by which chlorophyll molecules in plant cells capture photons from the Sun and use their energy to convert carbon dioxide and water into glucose.

The glucose stores the photon's energy in chemical bonds.

When your cells metabolize the glucose, the chemical bonds release the energy - the same energy that the photon carried from the Sun's core, where it was produced by the nuclear fusion of hydrogen into helium.
