Does weight loss help reduce the size of breasts?

I am 31 and after having my last child 2 years ago, I’ve been wanting to start a daily workout routine. Easier said than done, but I’m at a point now where I’ve been eating better and doing a little bit of exercise here and there. I’m big boned and I have a big chest. Unfortunately, my breasts are saggy, so I’m sure I could benefit from a lift as well. For now though, I just want to know if there are any recommended weight loss programs to help reduce the size of my breasts.
