(I apologize in advance for a downer of a comment, especially for the parts that are poorly argued.)

In general, I think the risk of important but unknown nutrient deficiencies from cutting out a whole class of foods is probably much more important than the animal welfare benefits if you are spending much of your life working on good projects. This is a concern with vegetarianism, but it seems much more severe for veganism.

I haven't looked into the literature in creatine in any depth (largely because my diet is long on creatine), but the evidence for material cognitive effects looks weighty enough that I would want to be careful before considering returning to a low-creatine vegetarian diet. It seems like this should probably get more weight, unless everyone else knows something I don't.

Based on rough estimates it seems like being a vegan is not going to be worth it on consequentialist grounds, at least for those who would e.g. be willing to pay an additional factor of 2 premium to eat meat periodically. For such people the question is: if raising an animal generates $X of economic value, can you generate a welfare offset for a small multiple of $X? It would be quite surprising to me if this weren't possible (e.g. just subsidizing the creation of a small number of more humanely raised substitutes should work, which I would guess is orders of magnitude less effective than realistic approaches). I haven't thought about this at too much length, largely because I think that the effects on animal welfare today are not too important either on contractarian grounds nor on utilitarian grounds (since they seem to have a minimal long-term impact, and the direct impacts are small compared to long-term considerations). But I do think that given the basic economic logic the burden of argument rests with the vegetarian advocate.

If it's a bad idea on consequentialist grounds, I'm not convinced it's a useful signaling exercise. Alternatives like "cut out the worst offenders," "reduce consumption by 90%," and "buy humanely produced products" seem much better both on consequentialist grounds and (consequently) also signaling grounds.

I second the recommendations for powersmoothies elsewhere (though I drink mine with milk, which I find more delicious and seems probably better health-wise).

Creatine is cheap and readily available as a supplement. Ultimately, foods are made up of chemical building blocks, and it seems arbitrary to consider the division "animal/non-animal" as especially nutritionally salient.

Also, "caring about lesser minds" is a good meme to promote, especially considering FAI, CEV etc.

Could giving good vegan food to poor people compete with other effective charity?

The idea: A charity develops or purchases nutrition-complete vegan food, ships it to areas of global poverty, and distributes it to the poorest for free.

The positive impact would be: Improved practical knowledge and demand to make nutrition-complete affordable vegan food, improved nutrition and purchasing power for the poor, reduced farm animal use without appeals to values or emotions toward animals (because the incentive is in-built into the wealth transfer).

It might be less effective in pure wealth transfer than, say, GiveDirectly, but the other upsides could make up for that.

I didn't see a charity quite like this listed. (A Well-Fed World advocates an approach like this, but supports a diversity of groups and it's not clear how homogenous and scalable they are.)

There's also a charity called Vegfam - - not sure how effective they are though.

Thanks for posting this Topher. When I was vegan, my diet was very similar to the one you described, and all in all I didn't find it that difficult. You'll notice the "was" in that sentence though - the thing that got me was eating out or eating socially with friends - I found it very difficult to maintain a vegan diet then, and so I found myself slipping. I'd be interested in how you deal with this - do you stick to a vegan diet even when eating out or going to friends houses, and if so, how difficult do you find it?

My solution for a while was to have a strict rule that I am entirely vegan in what I cook and by for myself, and vegetarian in other situations - like eating out - where being vegan is very difficult or inconvenient. This worked pretty well for a while. It's harder now because I'm living in a house with people who frequently cook together - which has a lot of benefits of saved time, money, and being more enjoyable and sociable - but aren't vegan. So I've slipped back to just being vegetarian across the board, but I feel somewhat uncomfortable about it.

For eating out, it's nearly always possible to get a vegan version of a non-vegan dish, even when there isn't anything vegan listed on the menu (e.g. pizza without cheese). However, it does perhaps take a bit of effort/practice to get over the "I'm being difficult" feeling - keep in mind that veganism is a positive thing, not something to feel guilty about. Failing that, chips and salad is a fallback option :-) As for eating at friends houses, I guess it's similar: you have to feel comfortable with requesting vegan food (or otherwise limiting your options). I've never been that into food, so these things don't bother me that much.

Protein, which will take more effort

Vegans can easily get arbitrarily high levels of protein by supplementing with pea or soy protein isolate.

As long as you aren't feeling hungry most of the time, you're probably getting enough protein. So I would say it doesn't really take any extra effort. e.g. If all you eat was bread, you'd be getting enough protein. I think most people in the west probably eat more protein than they need.
