And, if I have to explain the joke: it's just E=mc² (the Einstein thing ... well, the Einstein's thing's approximation), the energy (E) is the same for all mass (m) since the c is a constant.
You get the same 21 billon kcal from 1g of apples as from 1g of plutonium.
And since it's usually well known humans do not devour mass into pure energy that might trigger ppls sense of humour.
(Additionally the idea of eating metal to seek nutrition might be funny, but we do need some metals m/.)
Also "potential energy" phrasing is weird in that context.
There are 2 different definitions of calorie.
This "fun fact" mixes up the two definitions
It's not even two definitions, the kcal is absolutely the same, it's just used to measure two different things (mass energy vs the sum of what an average human can extract via chemical processes). I see you def understand that, but it's not a different definition of a calorie (in the same way as length vs width of an object isn't a different definition of a metre).
I mean, you can heat any old rock & make it look like that ... what I'm saying is that every rock, when heated to 500+°C, will gain delicious orange flavour, but scientists don't want you to know that!!
The oppressive class usually isn't a majority (capital owners/rich, religious fanatics, morning people), but they dictate so much more of our lives, what to feel, who to hate - so much so that they make the majority work for them against the minorities (that don't affect the lives of the majority in the slightest - but that's just how the oppressors retain control & power).
