My sister is in her 40s and is morbidly obese. Her weight is badly affecting her health. She cannot walk for more than a few minutes at a time. I am very worried about her health, particularly as she has a minor heart problem. She wants to lose weight, but I think may be in denial about how much she actually eats. She knows her health is at risk. Jokes that she might just drop dead one day, but seems unable to do anything about it. I understand that, because all of my sisters have a difficult relationship with food. Question is, what can I do about it? She lives a long way from me so I can't drag her out for walks or cook her meals. I have seen these diet chef things where you basically subscribe and they send you all the food you should eat - do you think they are any good? I would be grateful for any ideas. I am happy to spend a fair bit of money on it. Talking to her about it is difficult because she is understandably very sensitive about it.
