For the past 6 months or so I have been drinking tons of soy milk. After reading up on it so more I realized I was wasting my money since I’m not lactose intolerant and switched back to dairy last week.
Now, two wierd things are happening. I feel like I am in a state of overtraining and I am losing weight rapidly- I am 5’11" and was 193 two days ago and now I am at 189. I know weight typically fluctuates a few pounds in either direction, but in this case it’s fluctuating only in one direction. And yes, I do weigh myself the same time every day wearing, well, nothing.
I am not complaining about losing weight - I would like to get down to about 180-185, but what bothers me is that I suddenly feel overtrained. I know there is evidence that soy can slow down your metabolism - would it be crazy to think that switching back to dairy has sped up my metabolism in the course of just one week and thus increased my need for calories? I consume 3200-3500 a day, that hasn’t changed.
I am not a doctor or a nutritionist so take this with a large dose of electrolytes,
but I’ve been in a similar situation (my wife is lactose intolerant so I rarely have milk)
You may have lost much of the gut bacteria that breaks down dairy over the last 6 months.
This will mean you are not able to digest the milk as well as you used to, which may be the cause
of the weightloss and the overtrained feeling.
Don’t worry, over time the bacteria should build back up to strength again, you might be able to
help them on the way by taking some pre- and pro-biotics

Good luck !
Interesting - kind of makes sense to my very unscientific ears. Also worth noting - I am right now on Keflex, a pretty potent antibiotic, for a skin infection that I had several weeks ago. It went away, and then came back literally right after I switched to dairy. I am not blaming the dairy for the relapsed infection, but if I were suddenly not getting enough calories it would make sense that I would be more vulnerable to an infection. But yeah, it all feels very strange!

Bingo.
You are on antibiotics. They don’t tend to distinguish between the different bacteria and attack them all - that includes those handy ones in your digestive system. Plus as the last poster said you might be in short supply due to your previous diet already.
My initial thought is that soy milk has more sugar - but I’m not sure if that’s the case. Regardless, soy milk more higly processed so that could be a factor. Also, I know there are studies that show that a lot of soy can have adverse affects on the body - perhaps messing with your fat regulation is one of them in your case.
“After the rBGH milk is consumed, IGF-1 is not destroyed by human digestion. Instead, IGF-1 is readily absorbed across the intestinal wall. Additional research has shown that it can be absorbed into the bloodstream where it can effect other hormones.”
I’m probably a bit of a johnny-come-lately here but what is wrong with soy milk? I pretty much gave up regular milk and drink the Silk Light Soy Milk (regular and chocolate) a lot. I thought this was a good thing.

“The activity of SHBG was an average of nearly 9 percent greater on the soy diet. Since the extra SHBG tied up circulating testosterone, that led to a relative dominance of estrogen over testosterone.” Habito, R.C., et al. (2000).
