Re: Exercise Releases Brain-Healthy Protein
#52The connection between exercise and brain health has now been super conclusively and astonishingly shown, but what are some possible evolutionary reasons for this connection? Maybe the extra energetic investment in brain health is only justified when there is an energetic surplus, and doing exercise correlates with having extra energy available? (As opposed to starving and thus needing to conserve energy.) But that d…
A couple possible reasons: surviving to hunt, fighting/battle and celebration/training/building activities. If you have an elevated heart rate and exercising in the past that might mean going after food where you have to outwit, thus the brain needed to fuel/prepare for that. Additionally, exercise could be fighting, you might also need elevated brain performance during a battle for survival. It might also mean you a…
Also, you're probably learning during that time. Think about how young animals play: they practice a lot of the skills they need to survive. It builds dexterity, coordination, reflexes and strength.
Evolutionary speaking, those animals whose brains go into "extra learning mode" during exercise likely had a huge advantage over their peers whose brains didn't. Their brains picked up on skills related to hunting and survival and didn't waste energy building neural connections while they're sitting around not doing anything.

#53well im surprised to be the first person in this thread to ask this question (if i am not mistaken) but what about supplementing the protein instead of working out?
Generally, proteins you eat get broken down by the digestive system into their component amino acids. There are some notable exceptions where proteins can apparently get absorbed intact, but generally proteins are broken down upon injestion. Supplementing intra-venously might be the only option.
And even then this protein may provide negative feedback for the production of other unidentified proteins, which are kept in check by the exercise activity, meaning that flooding your system intravenously could lead to some undesirable or harmful results.

Or piss them off. Exercise is tiring and painful and time-consuming (especially if you count in after-exercise showers). Also, I don't like the whole culture around exercising and fitness. Gimme a damn pill or something. More seriously though, I really find no pleasure in exercise and would like to approach it in the most cost-effective way (i.e. maximum benefit for minimum time used). Any hints on exercise regime op…
Stronglifts. 3 days/week. Takes about 30-45 minutes. Alternate A/B each week. So week 1 is ABA, week 2 is BAB, repeating. A: Squats, Overhead Press, Deadlifts B: Squats, Brench Press, Barbell Row All exercises are five sets of five reps except Deadlifts which are one set of five reps. Ignore the marketing speak: http://stronglifts.com/5x5/ - has all the info you'd need and a free app to track your exercises. I highly…
That's very concrete advice, thanks! I'll look into that.

Interestingly, exercise itself actually helps get an energetically favorable type of energy to the brain in the first place: lactate.[1] Moreover, lactate in the brain triggers the release of BDNF, which causes neurogenesis.[2] I recorded a video conversation with the pioneer of the lactate shuttle theory behind this mechanism which may interest you. https://www.youtube.com/watch?v=lThFQM503EU [1] https://en.wikipedi…
Exercise also causes the release of endorphins in the brain that leads to a condition commonly known as "runners high".

Because an enormous chunk of the population still refuses to exercise and/or diet and articles like this help motivate some of that subset.

Wondering if you might have an undiagnosed medical condition.
I've been very a active exerciser my whole adult life. It's part of my identity.
Last year I started suffering from chronic fatigue. Exercise began to hurt. It hurt when I did it. It hurt afterward. I was tired all the time. I was gaining weight. I stopped exercising. It brought me no relief. Only resting did.
I knew something was wrong. Went to Doctor. Treated me like I'm a lazy ass who doesn't know how to care for myself. Fuck that dr.
I was on my own to figure this. I finally found out a treatment that works. Salt supplements and licorice root to address adrenal insufficiency. Day and night difference.
I feel bad for anyone who goes through something like that. It's not fair. And many people are dismissed by the medical establishment when they need help and compassion. It's awful how people get treated when they are sick but don't have the standard common diseases. The whole system sucks.
If it weren't for a long history of excellent health and fitness, I might thought I just don't like exercise. And never have the motivation to figure out how to get better.

Prehistoric humans likely exercised as a matter of course. They weren't sedentary. The brain evolved assuming the condition of exercise. naturally occurring byproducts of exercise were just always there for the brain to use.
This is my favorite explanation. It may be that the deficiencies of these chemicals are harmful and the release of them returns us to "regular" function, but since we are so sedentary it appears that we are getting a benefit.
Avoiding the teleological default misconception of "evolution means adding features to DNA," to boot.

Why do we care? Why cannot we just accept that some people have no desire/interest in exercise, and let them live the way they want to live. Anyone who likes exercise is already doing it. The constant drumbeat of "living healthy" that pervades the media and now the workplace is getting monotonous and annoying.
I can easily see somebody who isn't sufficiently motivated by being physically fit because they're too focused on intellectual persuits. This is now a(nother) reason for them to exercise.
And anyway, speaking for myself, I can see people being on the fence. Reading about articles or even comments online can be a tipping point to get (back) into a good habit.

It adds cost to the healthcare system and to health insurance that company pay when so many people are unhealthy.
Yes it does, but we've brought that on ourselves by insisting that pre-existing conditions (such as obesity, high blood presssure, etc.) cannot be cause to deny coverage or charge higher premiums. Smoking, interestingly, seems to be an exception to that standard.
There is no such insistence in the US. My insurer gives premium discounts to members who maintain a healthy BMI, blood pressure, cholesterol, and blood sugar level. So people with problems on those metrics do pay higher premiums than the rest of us.
