Will add to these great answers that there are many functions of fat beyond just energy storage. There are multiple types of fat that have various functions that help us survive. There are fat cells essential for breastfeeding, warmth generation, energy storage, signaling to other body systems, etc. Even the white fat, that is likely what is meant in this question, can adapt to help us stay warm in cool climates, for example. It’s useful to keep fat around in case of emergencies but if you aren’t using the muscle, it’s less beneficial to keep bulky muscle just in case.
