It’s my understanding that most fat (re: loss) is essentially metabolized and exhaled as carbon dioxide. What I can’t wrap my brain around is that even after eating a calorie surplus the weight doesn’t INSTANTLY appear – maybe after a heavy meal, but if it’s something just really calorie dense this isn’t the case. But the calories have been consumed so I don’t understand why the weight doesn’t reflect that instantly. So it seems like the fat gain side of thing might be actual magic.

Mass is just another form of energy, and energy is just another form of mass. A calorie is a measure of energy.
For weight gain/loss to be more complicated than calorie in/calorie out would require the human body to be the only thing in the universe exempt from the laws of thermodynamics.
