I am utterly confused and frustrated. This is going to take some background explanation...
I have been calorie counting for the past several months with some success; I was able to steadily lose doing this and my normal cardio routine. I realized I was starting to get "skinny fat" though, so I added weight training and HIIT to my routine about two and a half or three months ago. It seemed to be working great for the first month - I didn't lose any weight, maybe even gained a pound or two from water, but my measurements and estimated body fat percentage dropped slightly.
Then I went on vacation and ate myself into oblivion. I was still getting plenty of exercise, but by the time I got home I had gained eight pounds. I lost five of those pounds pretty easily over the next few days so I'm assuming it was mostly water from all my salty snack indulgences over vacation.
I've been working ever since to get rid of the last three, and then continue on with my weight loss from there (I still want to lose another 20 or 30 pounds). But now, weight lifting and HIIT aren't giving me results! The scale has been creeping back UP, I have gained an inch around my waist and two around my chest. At first I chalked it up to the fact that I had measured before my TOM, but now that that's over, it's STILL THERE.
I have been calorie counting long enough to know when I'm estimating too much or being too lax in general, and I really don't think that's the case. I have stayed perfectly within my calorie range for the last three weeks, lifted weights and did my HIIT religiously, and even tossed a few steady cardio jogs in there for good measure.
I've read numerous times that women don't gain muscle nearly fast enough to cause this kind of weight gain (but I have PCOS with a little more testosterone than the average woman, so please tell me if this would make a difference). Even so, muscle gain wouldn't account for why my freaking gut keeps expanding like someone blowing up a balloon. I would also think that water weight would A) not account for the extra seven pounds that I am above my pre-vacation weight and B) not cause my measurements to be larger.
This seems like a lot of rambling but I guess my question is twofold: first of all, can weight lifting and HIIT cause this for any reason, and second, what do I do about it? Normally my reaction would be, as common sense dictates, to decrease my calories a little and step up the exercise, but I would really like to avoid adjusting my calories because I had success with this calorie range just two or three months ago, at a lower weight than I am now, and have no logical reason why it would not be working for me now... And, if we are throwing logic to the wind, if I increase my exercise, might I keep gaining?
By the way, just in case it matters for anyone's answer, I weighed 178 before vacation, I'm 185 now, and I eat between 1600-2000 calories daily (big range I know, but I get a lot of exercise and this has never given me a problem before).
ANY and all help would be appreciated.
