"proper temps, humidity, and hydration should eventually take care of the obesity."
I used to think the same thing, except I even added "exercise" in the form of diggable substrate and other forms, but I've found out otherwise.
You can try reducing feed, high temps, halt feeding, treadmill, and anything else you can think of, but the sav will remain obese until the day it dies. I've tried it all on a 4yr old obese female and since last August she's only lost fat deposits within her tailbase, front & back leg areas. Her midsection mass remains the same size, just a little bit looser. In other words, she lost body mass (muscle), not fat mass.
From my limited experience with 3 savs, if caught early on, obesity can be turned around at the first signs. It's my belief that once they stay fat for any length of time, though, they're fat. I don't know if their bodies can't burn fat bodies within their midsections or if they just don't, but it seems to remain on every one that I've seen & heard of.
Granted, I didn't withold food from my female to the point of death, so I suppose there's a slim chance that she could've lost some fat had I pursued it longer, but my heart couldn't take it any more.
One thing I haven't tried that some people believe could help reduce obesity is an all-invertebrate diet. I'm still experimenting and may one day give it a try, but I've got my doubts.
As far as a sav getting sick from switching food sources, I seriously doubt it. These things have a cast iron stomach.
Have a good one!
