I'm sorry you feel like hell but I'm totally confused by what you've written.
You say you're severely dehydrated but also that you haven't lost any weight. Water weighs 8 pounds per gallon. When I let myself get even slightly dehydrated, I can easily notice a 1 to 2 pound weight loss. And drinking a quart of fluid - which I can easily do in one sitting - puts 2 pounds on me instantly. It HAS to because that's how much the fluid weighs.
You say you haven't lost any weight OR size but also say you look leaner and you think you've lost water and fat. Basically the human body is made up of bone, water (fluids) muscle cells and fat cells. If you think you've lost water and fat but you still weigh the same amount, the only possibilities are that you've added muscle cells or grown more bone. And the latter is highly unlikely. So, lets assume you've added some muscle cells.
Muscle is more dense than fat so, if you replace a given volume of fat with the same volume of muscle, you'll be the same size (volume) as before but you WILL weigh more.
If you replace a given mass (weight) of fat with the same mass of muscle, you will weigh the same thing as before but you WILL be smaller.
Sorry but the laws of physics say that it is impossible to remain both the same size and the same weight while replacing fat with muscle. Can't happen.
Its like, if you take a stretchy sock and fill it partially with with wiffle-golf balls and partially with real golf balls and then measure it size (volume) and weight. (Wiffle golf balls are those plastic balls with holes in them that are the same size as golf balls. Golfers use them to practice their golf swing.)
Now, take some of the whiffle-golf balls out and replace with them an equal volume of real golf balls. Since wiffle-golf balls and real golf balls are the same size, you would replace 1 for 1. Obviously, the sock will remain the same size but it will weigh more.
Conversely, if you take a bunch of wiffle-golf balls out and replace with an equal weight of golf balls, you'll only need about 1 real golf ball to replace about two dozen of the wiffle golf balls. Obviously, the sock will now weigh the same amount as before but it will be much smaller.
Take out a half-dozen wiffle balls and replace with a single real ball and the sock will be both smaller and heavier than before.
There is no way you can swap out any amount of wiffle balls for any amount of real golf balls and keep the sock weighing the same amount AND being the same size that it started out. The only way to have the sock be exactly the same size and weight that it started out is to keep exactly the same number of pingpong balls and golf balls that you started with.
As I said, I'm confused. Did you lose weight? Did you get even marginally smaller? Are you dehydrated? Do you look leaner and trimmer? What REALLY happened?
I'm also confused by your mention of having read somewhere that extreme low carb can cause Aromatase issues. Aromatase is an enzyme that catalyzes the production of estrogen from androgen. Women who STARVE themselves can, after a long period of starvation, inhibit aromatase so that they wind up with less estrogen...eventually with the noticable effect that they stop having periods. But a month of low carbing is definitely not going to have that effect. A month of totally starving usually won't if a woman is of normal weight to begin with. It takes a long period of anorexia nervosa for there to be any noticible inhibition of aromatase.
And, while men do have a small amount of aromatase, for a healthy male 30 year old male, inhibiting aromatase from producing estrogen for a month shouldn't have any dire health effects. It might possibly cause a very slight rise in your testosterone levels but probably less so than the amount your testosterone levels would rise from watching your favorites sports team beat a competitor.
Furthermore, I did a google search for documents containing both the phrase "low carb" and the term aromatase (search: +aromatase +"low carb") and it pulled up exactly one document and 3 advertisements across the entire web! I don't know that I've ever before run any search for anything that resulted in fewer hits. Here is the link
to my search. Perhaps you could tell us WHERE you read about a connection between extreme low carb and Aromatase.
I would also mention that searching on: +adrenal +"low carb" pulls up a plethora of articles discussing how a low carb diet helps to CURE adrenal fatigue. I went thru multiple pages looking for something - anything - suggesting that a low carb diet could cause adrenal problems. Finally gave up after looking thru the top 30 or so hits. Again, perhaps you could send us a link to whatever you read saying that low carb could cause adrenal issues.
I do wish you well and hope that you feel better soon. But whatever your problem is, I strongly doubt that it was caused by a month long experiment with eating under 30g of carbs per day.
