I disagree. There’s not a single excuse in the world for being fat. I do t give a fuck about big ass fat cells or hormones or whatever bullshit people like to peddle; the simple solution is to eat less and work out more. Keep bringing me excuses and I’ll keep telling this simple truth.Fat cells or adipocytes are permanent. They can be shrunk with weight loss, but they'll always be there. Worse, the shrunken cells may send out hormones and proteins to increase appetite and fat storage. That's why weight loss is so difficult to maintain.

Worse, people who are fat as children get a double whammy because they've been growing fat cells all their lives making it harder for them to lose weight and keep it off than people who got fat as adults. Source: fighting the obesity epidemic. Oxford [Oxfordshire]: Oxford University Press.
tl;dr Amber's doomed.
