how do navigate fluctuating body weight

Hi, bit of a weird one, pls be kind - i'm a few years out of drama school and in that time i put quite a lot of weight on (40lbs) i'm in the process of losing that weight now (nearly 30lbs down) but it means my spotlight material has me at different weights and i imagine that means different casting. How do i know realistically where my casting sits? and if my weight changes, do i need to update my reels more regularly to reflect it? Currently have a professional showreel from when i just graduated (thinner, younger..) and a couple of tapes up from 6 months ago (bigger, more recent)
