Mission: Heirloom is a cafe in Berkeley which is serious about paleo food. Their meat and eggs meet my ethical standards (no factory farmed animal products).
Their burgers are unusually tasty, and have a better texture than any other grass-fed beef I’ve tried.
They have a nice outdoor area in back – I recommend going there when it is warm outside.
The main drawback is limited variety in their entrees.
I wish there were more cafes like this.
I’ve recently noticed that dietary zinc/copper ratios may be important (e.g. may influence Alzheimer’s), and that my diet has had ratio which is too low (mine got down below 3 last year, when it should be more like 8 or 10).
The main contributors to lowering the ratio are chocolate, macadamias, and almonds. Each of those seems like a healthy food in moderation (i.e. as many nuts as I’d be willing to shell manually). But I often overeat them.
Animal products are about the only practical way to improve the ratio. Despite the stereotype of a paleo diet consisting of mostly animals, I’ve been getting most of my calories from foods that are fairly similar to what hunter-gatherers eat, while eating a below-average amount of animal products. Since that diet gave me more than the RDA for all nutrients except vitamin D, it seemed unimportant to eat more animals.
Oysters have by far the best zinc/calorie ratio. I find that adding oyster sauce to a stir fry is nicer than having whole oysters, but many brands have little oyster in them. Lee Kum Kee is a common brand that lists oysters as the first ingredient, so I’m using that regularly.
Should I take zinc supplements? I’m reluctant to trust nutrition from something that doesn’t resemble a whole food, but that would be the most convenient solution.
Alternate day calorie restriction seems to be one of the most effective ways of increasing my life expectancy, but it isn’t easy. I tried it about three years ago, but gave up because it interfered with my sleep. I started it again three weeks ago, and this time I seem to be adjusting to it.
One important difference is that this time I’m better informed about what it takes to adjust to the diet. I planned a strict induction phase of 7 down days (about 550 calories) and 7 up days (unlimited food), followed by a less strict pattern of 2-3 days per week on which I’m limited to around 1000 calories a day. (I ended up adding an extra up day after each of the first two down days, then switched to strict alternation for the remainder of the induction phase). The severity of the induction phase may be important at triggering adaptation to this kind of diet.
The second difference is that this time I’ve been obsessive about measuring my food intake to the nearest gram. I suspect that when I intended to eat 1200 calories a day in my prior attempt, I was actually getting at least 1400 calories and fooling myself into thinking I was following the diet. This time I’m using a good scale to weigh each serving.
After the first down day, I slept poorly (as expected), getting impatient for sunrise to bring me an excuse to get up for food. After about the fourth down day, waking with an empty stomach seemed normal enough that it doesn’t provide a motive to get out of bed, or to get food quickly when I do get out of bed. I hardly notice the feelings of hunger then, even though I ought to be hungrier than late in the previous day when I did notice some of the standard hunger feelings. My sleep isn’t quite back to normal, but it seems close to normal and improving.
I’ve been feeling full about 50% of the time. I felt noticeably hungry about 30% of the time at first, and now it’s more like 20% of the time. Hunger feels a bit less important now than it used to feel (i.e. it affects my attention less).
Weight loss wasn’t an important motive for changing my diet, but I hoped I would lose about 7 pounds. I lost at least 5 pounds by the end of the 5th down day (my weight fluctuated enough that it’s hard to evaluate it precisely). I couldn’t comfortably eat enough on the up days to make up for what I lost on the 550 calorie days, even when I became mildly alarmed at my rate of weight loss.
Then my weight rebounded within a few days, without any apparent change in my diet, to roughly what it was at the start. The obvious guess is that my metabolism slowed down to compensate for the reduced calories. I did feel noticeably colder in bed after down days. I also felt less mental energy, and when doing an easy hike on the day after the 6th down day I felt a need to take rest breaks that was unusual in that it wasn’t caused by anything like muscle fatigue.
During the induction phase, I practiced strict protein fasting (< 15 grams of protein per day) on down days due to guesses that protein restriction is more effective at causing beneficial metabolic changes, which might cause faster psychological adaptation. My results seem to provide weak evidence in support of this guess. My diet on down days was mostly sweet potato and lettuce, with modest amounts of other vegetables and sugar-free chocolate. This provided more bulk to fill my gut than is typical for this kind of diet, but that was likely offset by the lack of protein related satiety. I’m not restricting protein now that I’m out of the induction phase (although I expect to do so maybe once a month).
My heart rate variability mysteriously increased after the first down day, then declined to a much lower than average level after the fourth down day, and has fluctuated a lot since then (averaging somewhat below normal).
Why did I have enough willpower to get this far, when I probably didn’t have the willpower needed to do it right three years ago?
One factor is that I now consider the CFAR community to be an important tribe to belong to, so my sense of self-identity has changed to attach more importance to being able to make big changes to my life.
Another factor is having information that led me to be somewhat confident that by a specific, not too distant, date it would become a good deal easier.
A third factor is being more obsessive about measuring how well I was complying with the rules I set down.
The induction phase cost me a fair amount of productivity. For 17 days I wasn’t close to having enough willpower/ambition to start writing a blog post (and had similar problems with most other non-routine tasks). But now I feel that writing this post is easier than normal. It’s too early to tell whether that means I have more mental energy than before.
I don’t know how to get strong evidence about whether it is worth the effort. I seem to feel more self-efficacy. I now think I can set my weight to any reasonable target simply by changing my calorie target on 2 or 3 down days per week. But in order to be clearly worthwhile it needs to improve my long-term health. I won’t know that for quite a while.
I’ve seen some discussion of whether effective altruists have an obligation to be vegan or vegetarian.
The carnivores appear to underestimate the long-term effects of their actions. I see a nontrivial chance that we’re headed toward a society in which humans are less powerful than some other group of agents. This could result from slow AGI takeoff producing a heterogeneous society of superhuman agents. Or there could be a long period in which the world is dominated by ems before de novo AGI becomes possible. Establishing ethical (and maybe legal) rules that protect less powerful agents may influence how AGIs treat humans or how high-speed ems treat low-speed ems and biological humans [0]. A one in a billion chance that I can alter this would be worth some of my attention. There are probably other similar ways that an expanding circle of ethical concern can benefit future people.
I see very real costs to adopting an ethical diet, but it seems implausible that EAs are merely choosing alternate ways of being altruistic. How much does it cost MealSquares customers to occasionally bemoan MealSquares use of products from apparently factory-farmed animals? Instead, it seems like EAs have some tendency to actively raise the status of MealSquares [1].
I don’t find it useful to compare a more ethical diet to GiveWell donations for my personal choices, because I expect my costs to be mostly inconveniences, and the marginal value of my time seems small [2], with little fungibility between them.
I’m reluctant to adopt a vegan diet due to the difficulty of evaluating the health effects and due to the difficulty of evaluating whether it would mean fewer animals living lives that they’d prefer to nonexistence.
But there’s little dispute that most factory-farmed animals are much less happy than pasture-raised animals. And everything I know about the nutritional differences suggests that avoiding factory-farmed animals improves my health [3].
I plan not to worry about factory-farmed invertebrates for now (shrimp, oysters, insects), partly because some of the harmful factory-farm practices such as confining animals to cages not much bigger than the animals in question aren’t likely with animals that small.
So my diet will consist of vegan food plus shellfish, insects, wild-caught fish, pasture-raised birds/mammals (and their eggs/whey/butter). I will assume vertebrate animals are raised in cruel conditions unless they’re clearly marked as wild-caught, grass-fed, or pasture-raised [4].
I’ve made enough changes to my diet for health reasons that this won’t require large changes. I already eat at home mostly, and the biggest change to that part of my diet will involve replacing QuestBars with a home-made version using whey protein from grass-fed cows (my experiments so far indicate it’s inconvenient and hard to get a decent texture). I also have some uncertainty about pork belly [5] – the pasture-raised version I’ve tried didn’t seem as good, but that might be because I didn’t know it needed to be sliced very thin.
My main concern is large social gatherings. It has taken me a good deal of willpower to stick to a healthy diet under those conditions, and I expect it to take more willpower to observe ethical constraints.
A 100% pure diet would be much harder for me to achieve than an almost pure diet, and it takes some time for me to shift my habits. So for this year I plan to estimate how many calories I eat that don’t fit this diet, and aim to keep that less than 120 calories per month (about 0.2%) [6]. I’ll re-examine the specifics of this plan next Jan 1.
Does anyone know a convenient name for my planned diet?
0. With no one agent able to conquer the world, it’s costly for a single agent to repudiate an existing rule. A homogeneous group of superhuman agents might coordinate to overcome this, but with heterogeneous agents the coordination costs may matter.
1. I bought 3 orders of MealSquares, but have stopped buying for now. If they sell a version whose animal products are ethically produced (which I’m guessing would cost $50/order more), I’ll resume buying them occasionally.
2. The average financial value of my time is unusually high, but I often have trouble estimating whether spending more time earning money has positive or negative financial results. I expect financial concerns will be more important to many people.
3 With the probable exception of factory-farmed insects, oysters, and maybe other shellfish.
4. In most restaurants, this will limit me to vegan food and shellfish.
5. Pork belly is unsliced bacon without the harm caused by smoking.
6. Yes, I’ll have some incentive to fudge those estimates. My experience from tracking food for health reasons suggests possible errors of 25%. That’s not too bad compared to other risks such as lack of willpower.
I recently tried larger-than-normal methylfolate supplements. I had known that my genes caused problems with processing folate (MTHFR T/T), but hadn’t noticed any effects from supplementing at 800mcg/day.
Due to a report that several milligrams/day helped with depression, I changed from 400mcg/day to 2mg/day. I felt like my mind started working better within hours (although I haven’t seen much change in behavior). I saw a clear and large improvement in my heart rate variability starting after one day.
I’ve experimented for 5 weeks randomly altering my dose from 1 to 3 mg/day. On the week when I switched from 3 to 1 mg, my mood slowly got worse. I felt much better withing hours of switching back to 3 mg. I haven’t noticed any clear difference between 2 and 3mg.
I finally found a way to buy insects in enough quantity to satisfy my desire for nutrition from insects: World Ento, which sells dried crickets and cricket flour at a price per gram of protein comparable to seafood. (H/T Holden Karnofsky.)
According to Organic Value Recovery Solutions, crickets have impressive amounts of the nutrients I’ve found the hardest to get good amounts of. Here are examples of how much I’d get if I got my 2000 calories a day from crickets:
(using data for eggs from pastured chickens).
They have plenty of fiber and good amounts of most minerals and B vitamins.
The cricket flour tastes ok in brownies, but I’ll want some other recipe for regular use.
Update 2015-01-05: ThailandUnique has a better selection of insects. My favorite so far is the Big Cricket.
Yet another soylent competitor has appeared: Ambronite.
It’s higher quality and high price than Soylent or MealSquares. It has more B12 than MealSquares even though it’s vegan.
It’s low enough in saturated fat that I probably want to add an additional source of saturated fat to my diet, but that’s a nice problem to have – I’d want to add chocolate anyway. My biggest reservation is the high level of polyunsaturated fat – if I could get a version without the walnuts I’d probably be satisfied there.
Most ingredients look like what our ancestors evolved to eat, but the first two ingredients listed are oats and rice protein.
I’ve been thinking more about convenient, healthy alternatives to Soylent or MealSquares that are closer to the kind of food we’ve evolved to eat.
Here’s some food that exceeds the recommended daily intake of most vitamins and minerals with only about 1300 calories (leaving room for less healthy snacks):
Caveats: I’m unsure how accurately I estimated the nutrition in the processed foods (I made guesses based on the list of ingredients).
This diet has little vitamin D (which I expect to get from supplements and sun).
It’s slightly low in calcium, sodium, B12, and saturated fat. I consider it important to get more B12 from other animal sources (sardines, salmon or pastured eggs). I’m not concerned about the calcium or sodium because this diet would provide more than hunter-gathers got and because I don’t have much trouble getting more from other food. And it’s hard not to get more saturated fat from other foods I like (e.g. chocolate).
I don’t know whether it has enough iodine, so when I’m not having much fish it’s probably good to add a little seaweed (I’m careful to avoid the common kinds that have added oil that’s been subjected to questionable processing).
It has just barely 100% of vitamin E, B3, and B5 (in practice I get more of those from eggs and sweet potatoes).
It’s possibly too high in omega-3 (10+ grams?) from flax seeds in the Raw Chips (my estimate here is more uncertain than with the other nutrients).
The only convenient way to get oysters that keep well and don’t need preparation is cans of smoked oysters, and smoking seems to be an unhealthy way to process food.
Note that I chose this list without trying to make it affordable, and it ended up costing about $50 per day. I don’t plan to spend that much unless I become too busy to cook cheaper foods such as sweet potatoes, mushrooms, bean sprouts, fish, and eggs.
In practice, I’ve been relying more on Questbars for convenient food, but I’m trying to cut down on those as I eat more Brad’s Raw Chips.
There was a large shift in our ancestors diet about 3.5 million years ago to food derived from grasses and/or sedges. This has potentially important implications for what diet we’re adapted to. Unfortunately, the evidence isn’t specific enough to be very useful:
The isotope method cannot distinguish what parts of grasses and sedges human ancestors ate – leaves, stems, seeds and-or underground storage organs such as roots or rhizomes. The method also can’t determine when human ancestors began getting much of their grass by eating grass-eating insects or meat from grazing animals.
Book review: Paleofantasy: What Evolution Really Tells Us about Sex, Diet, and How We Live, by Marlene Zuk
This book refutes some myths about what would happen if we adopted the lifestyle of some imaginary hunter-gather ancestor who some imagine was perfectly adapted to his environment.
I’m a bit disappointed that it isn’t as provocative as the hype around it suggested. It mostly just points out that there’s no single environment that we’re adapted to, plus uncertainty about what our ancestors’ lifestyle was.
She spends a good deal of the book demonstrating what ought to be the well-known fact that we’re still evolving and have partly adapted to an agricultural lifestyle. A more surprising point is that we still have problems stemming from not yet having fully evolved to be land animals rather than fish (e.g. hiccups).
She provides a reference to a study disputing the widely held belief that the transition from hunter-gatherer to farmer made people less healthy.
She cites evidence that humans haven’t evolved much adaptation to specific diets, and do about equally well on a wide variety of diets involving wild foods, so that looking at plant to animal ratios in hunter-gather diets isn’t useful.
Her practical lifestyle advice is mostly consistent with an informed guess about how we can imitate our ancestors’ lifestyle (e.g. eat less processed food), and mainly serves to counteract some of the overconfident claims of the less thoughtful paleo lifestyle promoters.
