<human>: Please no insensitivity- my sister is very important to me and I don't have time for assholes with rude jokes. 
Anyway, with that said, my sister is 22 years old. She has struggled with her weight since pre-pubescence while watching me grow up to be a 5'4" skinny blonde. This has not been easy for either of us. I think about her all the time. I worry she won't be loved (even though she should find a man that loves her for who she is) and that her weight will cause her problems. I've seen her try to diet and exercise time and time again and nothing is sticking. I love her to death and she is so beautiful, hilarious, and fun to be around. I just want the world to see her like I do. She has SO much potential, and I feel like she's running out of time to make this big change in her lifestyle. I'm wondering if Reddit has any information about the most effective ways to lose a lot of weight (HEALTHILY!). If I had the money I'd get her a personal trainer, sign her up for those specialized meal programs, ANYTHING. But I don't. Help me help her, Reddit. I'm worried for her health and future, as diabetes and high blood pressure runs in our family. I know she wants to change.

Our relationship is very awkward. I can't go shopping with her, I can't talk about guys with her, I can't workout with her without feeling horrible guilt; I see that it bothers her. It's so heartbreaking and I need it to change. (Also important, we live 2 hours away from each other so I can't take on anything that requires me to be close by.)

Can you give me a shortened version of the text?
<bot>: My sister is obese and it is effecting our relationship because we can't relate to each other anymore. What are some cheap, effective weight loss methods I can encourage her to try?
