Generally I'm a live and let live person and on seeing a thread like this my reaction would be "mind your own business" so I expect a lot of those answers.
But I've been doing that for the past 5 years with my sister (she's 25) and she's gained maybe 7+ stone in that time.
And that's with me losing weight in that time, getting her to come exercise with me (her idea to come, I never try and push her to anything as that always has the opposite effect with all female members of our family)
It's getting to the point with where it's making me worried for her health.
The tricky thing is she won't talk about her weight, ever, so I can't tell if she's given up hope and assuming she's just made big like our mum's side of the family and there's no point, or if she genuinely is happy. Problem is she's now not fitting into some seats, is turning down theme park days with her friends and I think it's because she got turned away from a ride etc.
She also travels long haul a lot with her job and I really can't see how she's comfortable in a plane seat.
I could really help her - if she asked. But she won't and I don't want to make her feel like I'm judging her etc.
Any words of wisdom? It's that balance of loving her too much to want to upset her, and loving her so much that it hurts to see her health deteriorating at such a young age.
