Kudos to your friend going through with a reduction to pursue her passion!
In my case, I have a very small band width, so I cannot shop in regular stores. (In my city, there is exactly one shop that has my size.) As a teen and young woman, I simply didn’t have the money to even consider a 50€ sports bra, let alone a 100€+ one. And since the selection is super limited, I didn’t even find one in my size that would - no matter the money - give enough support for comfort.
Funnily enough, regular wired bras with cups still ended up giving better support than any sports bra I could find. But they still only work so well. (And I, by far, wasn’t as passionate about sports as to get a reduction, or spend my limited bra money on a semi working, ugly sports bra.)
I’ve studied nutrition science and we talked about what you described and yes, the blunt “truth” is that liposuction is the only reliable way to really get rid of “emptied fat cells”. There are a lot of things playing into the dreaded yo yo effect but the fact that it is much easier to refill emptied cells than to make new cells via division is definitely a big factor.
(“Truth” is in “” because I dislike this term in a scientific context but english is my third language and it’s pretty late over here so I am struggling to find a better suited word)
Good luck on your weight loss journey. It is an incredibly hard and brave one to take and I admire that you are trying.
