I mean, i wouldn't really blame people when they say "energy"; because the point of cellular respiration is to produce energy. Fat is metabolised to turn ADP into ATP which is used by the body in all sorts of thing and the byproduct of it is CO2 and water. Fat is a "store of energy" for this reason... but being strict; yes, this process produces energy, CO2 and water which is then expelled. Interestingly, people also don't really know much about how plants "eat". Plants don't "eat" the sun energy; they use this energy to produce sugar that is then processed by the mitochondria just like we do. So efficient and beautiful!
