ELI5: Why does fat melt when it is heated ( eg. fat cheese ) and does it act the same in our bodies ?
gpt
Within the human body, fat is contained inside cells. As long as those cells remain intact, the fats within cannot melt. Or rather, they're already liquid. Cheese is not made of cells, it's just a block of solid fat, so is free to melt and solidify as it wishes. Theoretically, you could solidify the fats inside human cells if you wanted to, for example, by putting a human in a freezer for an extended period of time.
