It's clear that you care, but I have to agree with the others that this isn't a good approach.
Perhaps she doesn't see herself as being able to lose weight with the way her life is. Obesity, her other physical health issues, and the mental health issues you've alluded to may mean that she isn't able to lose weight without other things being resolved first. The impression (perhaps incorrect) that I get from reading your posts is that you view this mainly as a lack of willpower on her part. Given the other things you mentioned, my own experiences, and the posted experiences of many of the other people on here, I would be surprised if that were true. And even if it were true, she is an adult who is responsible for managing her own health and making her own decisions. Also, unless your mother is fairly mentally subnormal, it's absurd to think that she isn't aware of the basic relationships between her weight and her other health issues.
If you want to help her, hold off of the judgement and condescension and offer her some real aid and support (telling her she should keep a food journal that you'll use to "hold her accountable" and remind her of what she "should" be doing ain't it). Since physical pain and possibly depression are issues that you think might be driving her poor eating and apparently aren't being controlled that well, perhaps you could offer to help her find and pay for treatment with a specialist in pain management and/or counselor. And since those are real and debilitating problems in themselves that may be having a major impact on her quality of life, there's no need to even get into your desire to have her lose weight.
And if you offer and she doesn't take you up on it? That's her prerogative.
Best of luck.
