Of course. But isn't methamphetamine a mix of dex and levo (50/50 split?). Still completely a different medication but may have some similarities if I'm not mistaken. So the OP was speaking about dex (Ritalin?).
Not sure what you mean by upegulated, are you saying BDNF is induce when low in blood sugar? Is it because "something" kicks in when the brain is low on sugar? I'm still not getting it. Is it sort of like adrenaline; when in a dire situation, it kicks in? BDNF kicks in when the body lacks food/sugar (i.e. fasting)?
Since you say it varies individually, how does one notice the effect if obvious at all? One thing I noticed though regarding fasting, some Muslims I know when on their Ramadan, they seem a bit better than their usual selves. Not sure if they "achieved" BDNF. AFTER Ramadan, it's another story. LOL. Then again not sure if that is "true fasting" considering they still eat something for the day at certain times and when they do eat, it's a binge.
At what length of time is it considered fasting? Considering there's only 24 hours in a day. If a person sleeps for 8 hours, is that enough of a fasting? So if a person works for 8 hours a day without any food, is that enough time to be considered fasting? So 8 hours sleep and 8 hours work, that's 16 hours of no food. There's still that 8 hour left over to make up 24 hours...
Regarding your quotes:
1) Take up a physical or artistic hobby with which you have no prior experience, or which you have not done since early childhood. It doesn't matter if it is running, martial arts, skiing, sculpting, tai chi, archery, knitting or carpentry. It should not be too social an activity - I would not recommend a team sport. Force your brain to learn something radically new.
I play guitar but have not done so regularly as I used to when in my teens. Would playing daily for a few minutes help? I'm a right handed, so if I buy a left handed guitar (which I want to experiment with either way), would this be a good example? A right handed playing a left handed guitar.
2) To the extent your academic activities allow it, fasting. Only hydration and maybe basic vitamins during the day, and enough food at night to allow you to sleep. Fasting has been shown to increase bdnf expression. If time allows it explore unfamiliar territory - visit nearby towns, neighborhoods you have not been to before, explore nature near your home. Trick your brain into thinking you are starved and exploring new territory looking for food.
When you say "starved" did you mean in terms of just food or other things as well? Like starving for knowledge or what?
So get on a water diet only?
Your quote #2 I may have done a part of it already by completely moving to an unfamiliar territory/city twice already in the past 5 years. I moved to cities I have no business being in, completely strange, etc. by choice. It had nothing to do with the BDNF at all since I've just heard of that word on this thread. The experience certainly opened up new territories but of course I'm still looking for more.
Our bodies and minds have tremendous capacity for growth, adaptation and regeneration, but often they do not do so on their own.
The brain part seem to be the hardest? Maybe I haven't tried harder. The body I think I have figured some out regarding growth, adaptation, and regeneration. There's always something new.
BDNF is upregulated by low blood sugar for some reason. How much you need to fast to notice an effect is probably individual. As for desoxyn - that is not dexamphetamine. Desoxyn is methamphetamine. Not the same medication.
