So this year I’ve stopped working out, and my grades have improved drastically, but at the cost of losing muscle mass and gaining fat, and becoming physically slower and lazier just as I became faster and more active intellectually. One effect I especially noticed was the disappearance of that perpetual state of happiness/satisfaction that comes from frequent physical exertion, which I think had a tendency to get in the way of a feeling of urgency regarding studies; why bother with tiresome and frustrating intellectual exercise when physical exercise yielded results and pleasure/satisfaction much more easily and reliably?
Anyway, this got me thinking: "I need to figure out a training that is optimized for intellectual performance. Aspects that might be interesting to work on would be:
-
getting as much blood (oxygen, nutrients) as possible to the brain, whenever needed.
-
minimizing the amount of other tissue (including muscle in excess of what is strictly needed for a comfortable daily life, and digestive organs in excess of what is needed to get the nutrients from the food).
-
optimizing the diet in order to feed the brain according to its needs while avoiding dietetical imbalances that would result in damage of some sort or another (too much sugar can damage the pancreas, too much protein and the kidneys can suffer, etc.)
-
something that is easy and quick to implement and follow, relatively inexpensive and straightforward; the idea is to save as much time, resources and energy as possible for the needs of studying/working.
These ideas I’m throwing around from a position of extreme ignorance. I’ve tried hiring nutritionists, but their diets were optimized for bodybuilding, not for intellectual efficacy, and were incredibly troublesome to follow. These involved about five to eight meals a day, large amounts of meat or meat substitutes, which is expensive to sustain, and me in a perpetual state of either hunger or digestive lethargy, plus permanent muscular soreness from the training regime that goes with it… and then there’s the supplements.
So, yeah, I’m no gwern, but I’d love to figure out a diet that allows me to work at maximum efficacy. Other concerns, such as feeling strong or looking attractive or even dancing well, are quite far behind in priority. How should I go about this? How about you lads and ladies? What’s your experience with dieting/working-out? More importantly, what does the research say?
P.S. I tried to read "Good Calories Bad Calories", but I never managed to finish it: it spent so much time attacking the current paradygm that I grew tired of waiting for it to actually list and summarize its recommendations. If anyone here finished reading that and drew out the conclusions, I’d love to hear them.
P.P.S. The main post will update as the discussion advances; once enough proper information is gathered, a top level post might emerge.
Are you sure there isn’t another factor causing improved grades? My impression was that it was pretty well-established that exercise improves mental performance.
Or possibly it’s the amount of time you spent exercising, which gave you less time to do other things? Were you spending a lot of time working out? If so, you may want to look into high-intensity interval training to get the benefits of physical exercise in as little time as possible.
Another idea: save your workouts for the end of the day, so you don’t have the post-workout feeling all day and will still feel like you need to get stuff done?
Comment
Yeah, I’ve noticed that sometimes I find it harder to do intense/hard thinking if I work out in the morning.
this is probably highly individual since I expect mood and stress effects to dominate minor physiological variation from different schemes.
Diet wise try intermittent fasting, lots of people see mental performance benefits. Be sure to get enough potassium and some saturated fats (whole milk is unambiguously good for lowering CVD rates). Vitamin D also has nootropic effects for people when recovering from deficiency. I recommend the version with K2, which lowers tooth decay incidence.
Comment
Even for people with lactose intolerance?
Comment
Lactose intolerance is easily and cheaply solved with lactase pills. Lactase is lactase, the pill form is chemically indistinguishable from the stuff your gut produces. I am lactose intolerant myself and average 2 cups of milk/day.
edit: I should mention that a small percentage of people show "true" lactose intolerance in that they get bad symptoms from ANY undigested lactose in their system, for these people lactase pills are not 100% effective. The majority of lactose intolerant people do have some tolerance.
Comment
Is there research on whether whole milk has the same good effects on lactose intolerant people that it does on lactose tolerant people? I’ve gotten cynical about theories based on the idea that the biology sounds plausible.
Also, when you say whole milk, are you including whole milk cheese, yogurt, etc.?
Comment
There’s nothing magical about milk that you can’t get elsewhere if you have concerns. http://consensus.nih.gov/2010/lactosestatement.htm#q4
In this particular case, the chemistry is simple enough that I would find it shocking to discover that drinking either lactaid, or regular milk with lactase pills would have any bad effects that overwhelm the benefits.
I’m not 100% sure about the micronutrient makeup of other diary products.
Comment
My concern is more that people who are lactose intolerant might have some additional features which mean that milk isn’t quite as good for them (or even slightly bad for them) which aren’t affected by taking lactase.
Comment
That would be very weird/unlikely IMO. It’s not like lactose is actually a variety of compounds the way, say, gluten allergies are actually an umbrella for quite a few things going on. In terms of n=1, I get regular blood panels and my system seems to be kicking ass on a milk heavy diet.
Good Calories Bad Calories is science journalism, not a diet book. Skip to the end if you want to know Taubes’ recommendations, or just get the New Atkins for a New You, which is a diet book. Short version of Taubes’ recommendations, which are essentially the same as Atkins, LCHF, Paleo, and other low-carb plans:
No sugar (including HFCS, Agave Nectar, honey, fruit juice, etc.)
No rice
No corn
No wheat or grains
No potatoes
Avoid all products labelled low-fat; e.g. skim milk, yogurt, cottage cheese, margarine, etc.
Different plans vary a bit—fruit or no fruit, milk or no milk, beans or no beans, cured meats or no cured meats—but that covers the essentials.
Comment
Minor correction: The paleolithic diet does actually allow potatoes and other tubers, as well as honey and fruit sugar (as those are all foods that were eaten prior to agriculture). They argue specifically against eating agricultural staples such as legumes, grains, and possibly dairy...not carbohydrates in general.
Comment
Thanks. I stand corrected.
Potatoes I can see, given the paleo diet’s motivations. Fruit and honey I find much more questionable, especially honey. But I suppose if you limit yourself to honey you’ve personally harvested from wild beehives without the benefits of modern technology like bee suits, you’ll probably be fine. :-)
The research on all of this is weak. There’s enough to justify elevating some form of low-carb to the null hypothesis. However I’m not aware of any studies that attempt to distinguish between the various flavors of low-carb diets like paleo vs. Atkins.
Comment
The main difference is that the organizing principle of LCHF/Atkins is just that—replacing carbohydrate with fat, sometimes even to the point of ketosis. Studies that compare fat/carb ratio in diets to health factors are applicable to the whole carb vs. fat debate.
The organizing principle of the Paleo memeplex is that there are a few key things about modern lifestyles that negatively impact health—some popular targets include shoe-wearing, chairs, sit-down toilets, sedentary lifestyles, and most famously high grain consumption.
It’s true that the paleo diet ends up being relatively low carb, since grains are the major carbohydrate source...but the central claim doesn’t actually make any testable predictions about carb/fat ratios. Rather, the major testable prediction of the Paleo diet is that the human body is ill equipped to digest ]large amounts of grain.
So the relevant studies would be those that look at the effects of grains and components such as phytates, gluten, lectin...etc, on leaky gut syndrome, digestive gut flora, inflammation, nutrient absorption, and such—there wouldn’t be much overlap between these studies and carb/fat ratio studies.
Maybe? It’s difficult to make broad prescriptive claims in nutrition, and I’m not sure "low fat" and "low carb" are precise enough categories. My guess would be that both low fat and low carb win out over the standard diet simply because cutting out either one is likely to cause some calorie reduction and a compensatory increase in vegetable consumption.
The argument from the Paleo-memeplex would be the "null hypothesis" for diet should be based off of what we ate prior to agriculture. In the absence of evidence, evolutionarily novel foods are guilty until proven innocent, while ancestral foods are innocent until proven guilty. (Of course, the question of what exactly constitutes an evolutionarily novel food is not simple)
Hehe—well, as a sweetener it’s certainly an improvement on straight sugar and as a calorie source it’s an improvement over starch.
Not sure what the objection to fruit would be, though. Fruit juice, maybe, since it’s easy to over-eat when your food is in liquid form.
Advocates of the Paleo diet would claim that that the ideal diet has near zero grain content. Sugar, on the other hand, is not intrinsically harmful...it’s just that we frequently overdose. The ideal diet does contain some sugars.
Comment
I think that the null hypothesis has to be based on the actual studies that have been done, not on poorly founded hypotheses about what our ancestors did and did not eat in the ancestral environment.
Fruits are probably only an issue for those of us trying to lose weight. However most of the fruits we eat have been bred over hundreds of years or more to be larger and sweeter (i.e. contain more fructose) than natural fruits. And some fruits are higher in starches than others, so if you’re trying to lose weight and failing, it’s worth cutting these out. Not all fruits are equal here. Berries are likely better for you (or at least less bad) than apples and bananas, for example. Again, this is not not really worth worrying about unless you want to lose weight.
I suspect a low fat diet actually does not win out over a standard diet, because low fat diets replace fats with carbs. Even worse, in practice they replace fats with simple carbs: pasta, bread, and the like. Low fat sweets are the worst of all because they replace fat with sucrose. Sugar and other simple carbs (and maybe all carbs) affect how your body stores and releases fat. The real story is much more complex than simply eating less and exercising more. You have to consider how and why our bodies produce and respond to insulin, glucagon, and other hormones that control fat storage and metabolism.
Basically no easy carbs. I had one diet that worked, and it was restricting easy carbs. Meats, vegetables, fruits, legumes, and small portions of easy carbs. No concern over fat, just no deep fried foods.
That’s kind of the opposite of every dieting advice ever… That it were right would be freaking scary.
Comment
Read Taubes. It’s actually not the opposite of every dieting advice ever. It’s the opposite of most dieting advice for about the last 40 years or so, but prior to that this was the standard weight loss diet going back into the 19th century (the first time in human history where obesity was actually a thing, or enough of a thing for doctors to worry about it.) For a long time Robert Atkins was widely viewed as a crackpot, but he didn’t actually invent the diet he put his name on. He was mostly just repeating what he had learned in medical school, and then used successfully in his clinical practice.
But yes it is scary, and Taubes explains in great detail how nutrition science went off the rails starting back in the 1930s and is only now beginning to recover.
Any thoughts about the intellectual effects of relatively simple (running, weight-lifting) movement vs. complex (martial arts, rock-climbing)?

Okay, giving stimulants a look:
Genistein: … I’m having lots of trouble interpreting that...
Modafinil: GAH! WALL OF TEXT! This is going to take some time… Luckily I’m on a holiday, but this is going to be interesting to research...
Comment
To a first approximation: modafinil has the same benefits and costs as methyphenidate and amphetamine, but with a better benefit to cost ratio.
You should give Juicing a try :] www.66dayhealthmastery.com Yes, I know, tacky site but it has worked wonders for me, my PCOS (Polycystic Ovary Syndrome), my skin and energy in general! :D I like this because she isn’t to the extreme everything-is-better-raw vegan and actually adjusted her beliefs when given sufficient proof AND backs up her articles with scientific studies and references. I still follow a high raw vegetalble diet, no milk and refined sugars but do occasioanlly indugle in some salmon, chicken or steak (I love steak too much to let it go) once or twice a week. She can go to the extreme though, in terms of buying a expensive water filtration system to make sure her water has the righ PH level and has no flouride, chlorine or any harmful chemicals in it but yeah that’s high level raw organic vegan tier hahaha, all you need really to start is fruits, vegetables and a juicer or blender. :D Just wanted to clarify that this diet only intends the fruit and vegetable juice as a supplament, not a replacacement to whole meals. I have enrolled to do Boxing or Muay Thai for physical excercise and before that I dancened, hula hooped, ran or did jumping rope for cardio and planking for core strengthening and it has worked but now I just want to achieve something elsewhile working out :p
Maybe, though, you just need to re-organize or be stricter with your schedule to include both working out and study time.
Edit: typing on a ipad is tricky
Comment
Many many "health" sites do this but actually have incredibly poor standards of evidence. Many are engaged in scientism, find any study that even tangentially links to what you’re talking about (many times even just rat studies!) and cite it, counting on the fact that pretty much no one follows up on reading through those studies.
I’m not saying you should stop doing something that has worked well for you, but beware generalizing.
Comment
I assumed she posted on her site the articles backed up by references she posted on her Facebook group but I can’t find them on her site and I can’t link you the facebook one (unless you make an account and like her page first), so I’m sorry for my assumption and poor writing that doesn’t do what she is all about justice.
She has a pretty straightforward and simple philosophy, it’s to alkalanize the body using only natural and organic means because cancer and tumors thrive on a acidic environment and it also reduces our body’s capability to absorb minerals and nutrients as well as impair a cell’s ability to repair itself. The body is naturally suppose to be in a slightly alkaline PH, around PH 7.3 to 7.4 and you don’t need to be part of her group to confirm that. Her philosophy states that the body is a wonderful natural machine capable of fending and fighting off most diseases and all that we need to do really is to not hinder it’s capability to working in optimum condition by eating the right things and avoding the bad. She does and offers a "juice cleanse", it’s what she’s famous or infamous for (you replace your meals with juice) but I didn’t and don’t reccomend her for that. I only reccomended her because Juicing as a supplement can do wonders in aiding alkalinizing the body as well as take in minerals and nutrients in a easy couple of gulps. I like her group because she is active in it and always answers questions I have like "Why don’t carnivores in the wild get more cancer?" And "so cow’s milk is bad for us because it is not meant for us what about about drinking human milk?" and always provides me with factual answers.
I aplogize for being unclear but I do not see how I am generalizing, fruits and vegetables are good for you and dairy (cow’s) and refined sugar is bad. Might have just gotten a wee bit teensy too excited on my first post because this is a health and fitness topic and I am sort of a healh and fitness buff :p
