Glad to hear that the check up went well. My female Camille weighed from 130 to 140 depending on how much I gave her to eat and the type of feeders. Worms put allot of weight on her. If you post some photos of Yuki we will be able to tell if she looks fat or not.
Everyone at the vet loved her. They don't handle exotic reptiles at all, so I wouldn't be able to bring her there if she got ill, but it's still more than enough for X-Rays and fecal tests. It's also local, so easier for us to reach for something so small. Apparently she smiled while getting her X-Ray too! I think she was trying to bite the vet, but everyone seemed to like her X-Rays.
I very rarely feed her worms, when when I do it's rose beetle larvae

She loves those fat worms. Have to cut their mouth mouth parts off though, since they look like they could really bite hard.
1 sometimes 2 times a week she gets fed. Usually a mixture of crickets, grasshoppers and roaches, gutloaded of course and calcium/vitamin/d3ified depending on the week. If I have phoenix worms she'll get some of those, but they're kinda small for her so I don't buy them often (Marimo wouldn't touch them at all). When I have some of her favourite fruits and veggies at home, she gets a bit of those too!
I'll post some pictures when I get home and TRY to get some measurements... but she usually doesn't do anything other then puff out and ball up when I try to measure her, which makes it fairly difficult to get proper measurements!
::EDIT::
Here's a recent post with some pictures of her (and Marimo too)

Now you can easily see why I think she might be fat

Her legs just look really stocky, not sure if that's how they should be or not!
