I don't think it was discussed before, though personally I think that while it might effect it slightly, being on a high protien diet wouldn't account for a temp as low as in the 97's.
When you say it was 97.7 was that your waking temp? does it stay steady in that range throughout the day or does it try go up a bit as the day goes on?
I almost forgot in the posting of the links, here is another valuable website to help figure out the temperature problem.
Wilson Temperature Syndrome
I'm really having excellent results with the raw adrenal and raw thyroid I'm taking now. I've seen a huge temperature increase and in doing so also have seen a huge jump in my metabolism, which means I can stop being so obsessive with what I do and don't eat! In fact I'm going to have to add in some extras to stabalize my weight, since I don't want to loose any growth and since my temp went up I'm waking up each day anywhere from .5 to 1 pound lighter this week! It's nice to get rid of the few extras I put on during the holidays, that's all I want gone. So far, I haven't lost any in the chest it's just been from the tummy pouch I've been annoyed with.
I guess I started looking into the raw glandulars since I'm using BB and know first hand that glandular therapy can work really really well, so it just made sense to me to go that route. It took 2 weeks of the adrenal pills to see an increase and then I added in the thyroid this week to see if it would help get it up the rest of the way. Since adding it, is when the weight began falling off, and my temp has increased some more. I'm still waking with about 97.7 temp, and it's a very gradual increase throughout the day, but by night, it's 98.6 for the last 2 days!
