Predicting weight change potential

[Ushikawa]

So I think I recollect something regarding how to predict if a guy can add/lose weight related to developed percentage, like ess developed more likely to be able to lose/gain?

Any new thoughts are welcome as well, even if they are anecdotal.

This is anecdotal: I've always thought that players could have their weight changed once in their career and that was how it worked, maybe with some slight randomness involved.
