Are there people who are just plain lazy?

Yeah, I would definitely say the weight is the main problem- it makes you sick at that point, it's not just about how you look. It hurts to move, it hurts to breath... she's got a real health problem and you need to encourage her to address it. If she feels better in her body (again, it's not vanity, it's about being able to walk with ease), she will have more energy to do the basic things- she's probably stuck on facebook games because it's a distraction from feeling like crap all the time. Close to 400 lbs is seriously obese and she's going to end up bedridden if there isn't some intervention soon. Approach the subject with sensitivity and support- consider offering to take family walks after dinner or small changes that you can all do.
