Book recommendation for dealing with weight gain or self love?

Hi!

My 26 yr old sister has gained weight and is having trouble dealing with it. We come from a family where everyone is above their average weight but for some reason my parents are only coming after her. My mom tells her things like “when do you plan on losing weight, you should take better care of yourself” and so on. Although she never says it out of a bad place or with bad intentions, she says it often and it is annoying for my sister. On the other hand, my dad is more direct and nonchalantly tends to tell her “look at what you look like, you’re like a pig, a girl your age should not allow herself to look like that” and so on. It’s very, very hurtful and it’s hurtful for me to look at her in so much pain as everyone is telling her directly or indirectly that she is not good looking. I am telling them to stop but all they say is “it’s nothing personal”.

I, unfortunately, am not much help since I’ve been through the same thing and I’ve always been so sensitive about it. When I was going through it, nothing and no one could comfort me so now I don’t know how to comfort her. I have eventually decided to try and accept myself for what/who I am and that’s when change happened.

However, for her, she is not that much into self love/self help. When discussing eating healthier, for the sake of her health, she says she tried, doesn’t like it, doesn’t feel like it and so on. Although she says she hates the way she looks and lost the will to buy nice stuff for herself as she says she doesn’t look nice in anything.

So, now I am at a point where I think the only way I can help her is by recommending a book on how to deal with things like this. We’re also searching for a good therapist so we’re already working on that. Whether it’s a self love book on accepting yourself, a kinder approach on losing weight, or basically ANYTHING to help her and help her feel prettier I’m up for it. Thank you in advance.
