Eh... I was gonna say that many strong man are fat... and that fat can help with energy consumption and maybe theres a lot of muscle under it so lets not fat shame people...
But thinking twice... did they have enough food suply to sustain it? If they were tight on food then I kinda agree...
I think it was only 3 years inside the tower
For everyone else it was an instant
If time was all it took to lose weight, there would be no obese old people. There's been no extended and/or repeated starvation scenarios either.
Also, three years passed but that fat man still didn't loose weight??
