Me, neither. I've been a chubby 20 BMI (it looks chubby on me), but never fat. But I don't miss a single thing about being chubby. Not even the slightly larger boobs (in fact, I'd rather have C cups instead, TBH). It sucked being chubby. I hated feeling my thighs rub together. I hated feeling fat in my belly. I hated the way my arms looked. I hated the fact that, in spite my knowing otherwise, I was still being called skinny and that I looked fine.  No, I didn't look fine. I looked fat. I felt fat. For me, I was fat. There's nothing wrong with hating your body if it means you'll improve yourself.
