This is just my opinion but I think she should learn to love herself for who she is first, self-love is so important. I'm not the thinnest of people and I've put weight on over the past 2 years due to medication, poor diet and very little movement but I'm honestly not concerned what other people think of my weight, I've managed to manifest a guy into my life who isn't bothered either, it's all about the love you have for yourself.
