I don't think there's anything you can do at this point but lead by your own good example. Unless people are ready to change, they're just not going to, no matter what you do. My wife's a type II diabetic, significantly overweight, has chronic knee pain, etc., etc. We've been eating Paleo for about two and half weeks now, and the things that finally convinced her to give it a real try were: 1) she's sick and tired of feeling sick and tired, and 2) watching a good friend of ours slowly go down hill health wise, to the point that she may have to leave work on disability, and my wife not wanting to end up like that. I doubt your Mom will be open to making a real change until she has that kind of epiphany of her own. In the mean time, I'd say keep doing your thing, and don't push your Mom, or she's just going to resent you for it. I think it's perfectly reasonable to have a discussion with her about your concerns, but if you've already done that, drop it. And threatening to cut her off from her grandkids would be about the worst thing you could do. You may not like her dietary choices, but it's not like she's smoking crack, even though you may feel like the end result isn't much better.

It's been my experience that the best "advertisement" for a nutritional path is the health and success of the people who are on it. Especially where family members are concerned, there is usually a lot of history behind family members and their resistance when ANOTHER family member wants to change a cherished pattern like eating.

I'd suggest figuring out what some of her favorite things are, and then, when she visits or you visit her, bringing paleo-friendly versions of her favorites. If she likes processed-meat-and-white-bread sandwiches, Try bringing roast beef or turkey "roll-ups" instead.

I can't suggest anything for the candy. As long as she's still eating sugar, maybe you can slowly move her towards carrying, say, something with 65% or better dark chocolate content -- at least as a starting point.

Invite her to come do outdoor PLAY things with you and the kids... and encourage her to participate. Yes, it might mean that you and the kids will have to slow down to her pace, but the point is to get her to choose for herself to be more active and participate more in the process.

Sometimes, it's just about giving people the chance to feel like they have control over their own choices. In the end, she'll have to make changes because she WANTS to make changes--forcing her won't produce lasting change, and manipulating her will only cause resentment and true anger, and drive her even FURTHER from desiring to make any beneficial changes for herself.

Any time you see her making positive changes, reward them. Provide her with tools -- cookbooks, information to manage her 'gas' (and maybe some articles to show her that the gas may actually be from the grains, not the veggies)... basically, guide her along the path, but don't try to push her along it... let her see because you lead by example. And don't let dad nag, either -- that won't help, and could seriously impede her progress.

Hope this helps. Maybe, at some point, she'll be willing to join a community where she can ask questions and maybe get some more encouragement -- we'll be happy to help then, too.

The best thing I did was to get my sister to read robb wolfes book.

My mom is type 2 as well and all she ever does is cut me off. She's also an alcoholic, so she never remembers anything I say to begin with.

She's also a big comfort food person, so what did I do? I bought her the Primal Blueprint and Paleo Comfort Foods. She's on board with "low-carb" diets but is still lipidphobic. All you can really do is let parents explore on their own. If you push them too much, they'll probably get antsy about it and push back more. :/
