All sugar is the same for me, if we needed fruit then I would have died 5 years ago, and my skin certainly wouldn't have cleared up. In my experience even a little bit of sugar throws me off balance because the body starts using a different fuel source (sugar as opposed to fat), which takes time and energy to switch back-and-forth. While this is happening, it's party time for all hormones (good and bad) because our liver is far too busy dealing with the sugar to check the guestlist.
Avoiding sugar is not an issue for me now, because I don't crave it. I certainly used to though, because my body thought I needed it. This kind of craving is normal for anything that gives us a temporary energy boost.
Refined or unrefined has no difference. In fact I prefer straight alcohol to sugar because it goes through your system faster.
All I know is that in the 80's every bodybuilder drank milk like crazy, like 1 gallon every day and no one had even one pimple..
Hah, man. I can't speak for the 80s but all the bodybuilders I know today have terrible skin and their hair is falling out. Of course there's more to blame now than milk, but it struck me as an odd example.
You prevent stress by not preventing stress. Figure out what's important to you (this will be different to anything you read, different to anything anybody will tell you), and focus on that. You chose to be a teacher so helping kids feel better is part of who you are it doesn't mean it will be easy but you'll be doing the right thing. Sometimes if you get fired up it just means you care. You shouldn't have to apologise for that or feel guilt, embrace it and suddenly that energy will be a good thing. Sweat isn't bad either do you think athletes worry about that? I sweat 12 hours a day sometimes hauling lumber and my skin doesn't care. It's normal. Humans would be extinct today if we never broke a sweat.
Health and all that is obviously good too, but it just gives you more energy and it's your choice what to do with it.
If poor health doesn't affect your hormones it affects something else, whatever part of your body is most vulnerable. This is always going to be different. It's like being in a car crash and asking why you lost your leg, and the other guy lost his arm.
There's probably an overweight forum somewhere with someone asking "Why doesn't this person with acne gain weight? HOW DO THEY DO IT?"
