The dieting was pretty hardcore. I was losing 7lbs every week. I'd have a Diet Coke, two egg whites in the morning, a piece of chicken, then another Diet Coke.“I was always hungry, and irritable. My body resembled a little baby bird with its mouth open, crying, 'Feed me, feed me,' and you realise momma bird ain't going to feed you. It's hard."
