Is this possible?

She may not realize how much she's eating, especially if she's snacking. That was a big one for me. I would grab a bag of something thinking i'd only eat a little bit. Only to find i've eaten the whole bag while at the computer or reading because it didn't register what i was doing. I think the first step would be to get her thyroid under control, then talk to her doctor about weight loss. It'll be a slow process, but hopefully worth it to her.
