A Month of Eating Vegan

Kale Plant Closeup

Kale: A common food during my vegan month.

While I was doing the Paleo Diet last year, an acquaintance suggested that I try eating vegan. In his opinion it was healthier, and he pointed out that some top athletes are vegan.

So last month I finally gave the vegan diet a try, and something happened that I never expected (more on that later).

Although the vegan diet can arguably be healthy, it’s of course possible to eat a very unhealthy vegan diet also.  The only requirement is to eliminate animal products; there’s no requirement to eliminate junk food.  So I could have eaten nothing but Oreos for the month and my diet would still have qualified as vegan.

But I decided to eat a mostly healthy vegan diet based on the book “Thrive” by Brendan Brazier and monitor the effects.  I didn’t do a detailed analysis involving blood tests like I did with the Paleo Diet, but instead just weighed myself and observed how I felt.

The Effects

I felt no different eating vegan than I did eating my regular (also healthy) diet.  I felt good off the vegan diet, and I felt good on the vegan diet.  No difference.

Sticking to the diet was easier than I’d anticipated.  I didn’t feel like I was missing anything important and didn’t have any cravings for meat, milk, butter, or anything else that I’d eliminated.  Of course it would have been nice to eat those things, but not because I felt I “needed” them.

I felt less deprived eating vegan than I did eating paleo, but the comparison isn’t really valid because when eating paleo I ate 100% healthy (nothing remotely processed) whereas on the vegan diet I allowed myself to eat some less than 100% healthy food – like Oreos.

According to the scale, I dropped 3 pounds. It’s possible that in normal circumstances I would have lost more than 3 pounds, because when I weighed myself at the start of the month I’d just been mostly sick and not exercising for a week so my weight may already have been down a bit.

Due to the small weight difference and my non-precise fat calipers (that I bought while eating Paleo), I’m not quite sure what types of flesh I lost. I’m going to guess that I lost some fat, some muscle, and maybe a little bit of brain also. Just kidding about the brain.

Ethical Issues

I decided to try eating vegan primarily out of curiosity – to see what it would be like and what effects it would have on my health.  However, I think MOST vegans follow their diet primarily for ethical reasons rather than health reasons. So to have a more complete experience of eating vegan, I decided to investigate some of those ethical reasons more thoroughly.

Cow Photo In Loblaws Tells A Lie

The photo of grazing cows above the meat tells a blatant lie. I took this photo at my local grocery store (Loblaws). The dead cows sold at this store didn’t live lives anything like the cows in the idyllic photo above the meat.

I started by watching the movie “Earthlings” after a couple weeks of eating Vegan (you can watch it for free online at Earthlings.com). The movie has some major flaws (one example: they discount all animal testing as useless, claiming that results of animals tests aren’t relevant to humans). But despite its flaws and its unpleasant images, I think it’s an important movie, because if we have choices about how to eat, dress, etc (as we do), then I think we have a moral obligation to make ourselves aware of what we’re participating in. And “Earthlings” does a good job of making that clear.

After watching the movie, I spent many hours researching how accurately the movie had depicted the reality of how animals are treated. And I spent many hours thinking through what I’d learned, and debating with myself to decide how to eat going forward. For a few weeks there was quite a war happening inside my head. Below I’ll explain some of the issues I was considering.

In the end, I made a decision that I never expected would happen when I first started eating vegan – I decided to stick with it (mostly). I’m not eating 100% vegan now (more on that in a bit), but am pretty close.

Here’s some of the debate that I had with myself:

Meat Is An Unnecessary Luxury

Leo Tolstoy pointed out that if humans can live healthy lives without eating meat (and we can – just look at the millions of vegans who do it), then meat can be considered a luxury. If you like, you can check out this excerpt from an essay Leo wrote on that topic.

Can I justify killing an animal simply so that I can enjoy food that tastes good? I don’t think I can. To put it more broadly: Is it ok for me to cause suffering so that I can enjoy a luxury that I don’t need? I don’t think it is.

But the situation isn’t that simple…

Vegans Kill Animals Too

I learned from the Wikipedia article on Veganism that a guy called Steven Davis pointed out that vegans cause animals to die also.  Many small animals (field mice, gophers, etc) are accidentally killed during the production and harvesting of the crops that vegans eat.

If you look at the numbers of animals that are killed, it can be reasonably argued that certain types of omnivorous diets cause less overall deaths than a vegan diet. For example, Steven Davis calculated that killing and eating pasture-raised cows likely results in fewer animal deaths than eating vegan.

“Pasture-raised” is important here, because typical cows sold in grocery stores were fed unnatural diets of grain, and that grain needs to be harvested. So eating grain-fed cows would have killed many more small animal deaths than a vegan diet, in addition to the killing of the cow.

Davis’s argument brings to light an unfortunate reality: We can’t live without causing death and suffering. But that fact doesn’t justify causing suffering willy-nilly. Of course it’s important to minimize the suffering we cause.

I think Davis’s argument is a strong one, and I think it comes pretty close to justifying the eating of some meat. Furthermore, I think slaughterhouse deaths are probably shorter and less painful than the deaths that those same animals would experience in nature at the teeth of their predators.

But again there’s more to the story…

Considering Not Just Death, But Quality Of Life

When we eat meat, I think it is necessary to consider not only the fact that we’re causing animals to die, but also the conditions in which we’re forcing animals to live.

A field mouse lives a happy natural life before it accidentally gets sliced up in a farming combine. A typical beef bull on the other hand goes through dehorning, castration, and branding all without anesthetic, and then spends most of its life on an overcrowded feedlot living and sleeping in a carpet of its own manure, before being slaughtered at about 10% of its natural lifespan.

As Davis pointed out we’re going to cause animals to die whether we eat meat or not. So I think the new question to consider is: “Can I justify causing animals to live miserable lives so that I can enjoy food that tastes good?”

Again I don’t think I can. I think causing them to live terrible lives may be even worse than killing them.

So, if I can find meat from animals that I know:

      • lived happy lives, and
      • lived in such a way that they didn’t cause the deaths of other animals

…then is it ok to eat it? I think this is getting closer to the right answer. But there were a few more issues that I considered, including…

Levels Of Consciousness

I think most people would agree that the more advanced/complex a life form is, the worse it is to destroy it. So for example it is worse to kill a dog than it is to kill an ant.

I think what makes us more averse to killing dogs than ants is the fact that we’re aware that dogs have access to a wider range of experience and emotions. To put it another way, I think you could say that a dog is “more conscious” than an ant. And I think we have a natural aversion to destroying consciousness.

So if we’re going to be killing animals, I think it is best to kill less conscious animals (i.e. lower life forms). So if we have a choice between eating a pig and eating a fish, it’s probably best to eat the fish, all else being equal.

Humans Are Designed To Be Omnivores

Before I decided to try eating vegan, my primary justification for eating meat (which I’d never thought about deeply) was that eating meat is just the way things are meant to be. It’s natural. In nature, animals eat other animals. Looking at the human body, there are compelling signs that we’re designed to be omnivores.

Those facts led me to previously conclude that “there’s nothing wrong with killing and eating animals”.

After having thought through all the issues more thoroughly, my current response to those facts is: “Yes, I agree that humans were designed by an at least somewhat random process of evolution to eat meat, but so what? Society has advanced to the point where we do have feasible alternatives to torturing and killing animals in order to survive. And as a species we’ve not only evolved to eat meat… we’ve also evolved to the point where we can reflect on whether our evolutionarily-designed urges lead us to the most ethical and compassionate outcomes, and to the point where we have the freedom to choose our actions based on those reflections.”

The Environment

The production of meat does many times as much harm to the environment as producing an equivalent quantity of plant foods. ’nuff said. You can do some searching online to confirm this for yourself. Environmental harm was another factor that I considered when deciding how to eat.

A Few Other Considerations

And there were a few other issues I considered that I still haven’t mentioned yet. For the sake of brevity, I’ll just list them off here in point form:

      • Is it morally worse to intentionally kill an animal in a slaughterhouse (or require someone else to do so) than it is to accidentally kill an animal when harvesting crops?
      • If I wouldn’t kill a pig or a cow in a slaughterhouse myself, can I justify requiring someone else to do it for me?
      • What is the meaning and implications of Leo Tolstoy’s statement that “as long as there are slaughterhouses there will be battlefields”?
      • What if there is a God who intended us to eat meat?
      • As a vegan I might need to drive farther to get my food, and I might buy more plastic (i.e. vegan protein powder comes in big plastic jugs). The plastic and driving both harm the environment, which indirectly causes animals to die.
      • How extreme is too extreme? For example – How far can one go with attempting to analyze the precise level of harm caused by every action before doing so just becomes ludicrous? Should I wear a mask over my mouth 24/7 to avoid killing bugs or microorganisms by unintentionally inhaling them? (I think not)

The Final Decision

After pondering the issues for a few weeks, these are the foods that I’ve decided to eat going forward:

Anything Vegan – Of course.

Fish – A relatively low life form that lived a “happy” life in its natural environment.

Dairy & Eggs from happy animals – But happy cows & chickens are pretty rare. Even “free-run” chickens usually spend their lives crowded warehouses walking around in their own feces and never see sunlight. So although I’d eat milk and eggs from truly “happy” cows & chickens, they’re so hard to come across that I probably won’t do so anytime soon.

Earthlings Again

Despite its flaws, I have to credit the movie “Earthlings” with motivating me to more thoroughly research the implications of my diet, and to think deeply about how to eat in the future. I knew before watching the movie that I was causing animals to die and live unnatural lives, but I didn’t really know. To put it another way: my head knew, but my heart did not know. The movie helped my heart to know.

I’d encourage anyone who watches the movie not to make any knee-jerk emotional decisions about how to live, but to take the time to do more research and consider all relevant issues.

I Might Have The Wrong Answer

I’m not certain that I have the right answer about the best way to eat, and I don’t think everyone should eat exactly how I’ve decided to. I’m very open to new points that I haven’t considered yet, and to changing my diet in the future. So if you have anything to add to what I’ve written here (or have any disagreements), please let me know in the comments below.

    Great article, love your writing style. Informative and entertaining. Will be coming back to your blog to read some of your other posts. Will your month long escapades eventually turn into a collected work? as in book?

    Thanks for sharing.

    Hi Justin

    Your post is very well written. I am from India and have been mostly vegetarian throughout my life and turned vegan a little over a year ago. I did eat all kinds of meat for 4 years of my childhood when we lived in Germany (I gave it up after returning to India).

    In India, the general opinion is that meat eating is morally wrong. Those who do, acknowledge it as a vice and many choose to be vegetarians on certain days of the week at least. So the belief is that God never meant us to eat meat and it is not good for our bodies or our minds. You can research Hindu or Buddhist philosophy a little more to understand this different take on the topic.

    Some reading material on humans being omnivores can be found here http://michaelbluejay.com/veg/natural.html

    About your comment on vegans using too much plastic- You and I might have come to veganism from different starting points but that is not how it happened for me. Since so many processed food options went out of the window after turning vegan, I was forced to source more fresh vegetables rather than buy boxed foods. My trash bin took 4 times longer to fill up after I turned vegan. I also would have never gained so much environmental awareness had it not been for reading material on veganism.

    There is a spiritual angle to it that has left me with such compassion and gratitude for my life in this world. I have so much respect for this world and everything in it, that I cannot go on using plastic mindlessly.

    May I suggest that as part of your research and discovery phase, you should try to visit a farm sanctuary. You have experienced how it feels to take a life for your food. It would also be worthwhile to experience how it feels to give someone the gift of a free and long life and how that experience can make you feel.

      Hi Sonl,

      Thanks for your comments. About the idea of what God intended, we’d first need to define “God” and determine whether he/she/it exists. This is certainly a topic I’m interested in and enjoy discussing, but since I think it’s too extensive to cover in these comments, I won’t get into it here.

      Thanks for the link to the evidence for humans being herbivores – the information looks both thorough and concise – I’ll read through it, and of course to form a balanced opinion I’ll also look for evidence supporting the opposing view. I’ve heard evidence in the past supporting the omnivore argument, but this isn’t something I’ve researched thoroughly yet.

      About vegans using too much plastic, I’m not sure if that’s actually true, and I’m sure I could survive without buying protein powder in plastic jugs if I chose to. I just mentioned the “plastic” and “driving” examples to point out that in general there may be additional consequences to diet choices that aren’t immediately apparent (such as the harvesting of crops killing small animals).

      Thanks for the suggestion to visit a sanctuary. It isn’t something I have thought of doing, but I agree that for the learning experience it is probably worth doing.

        It’s actually not that difficult for me to get all my vegan groceries within a couple miles of my house. And I live in a fairly typical working class neighborhood in a fairly typical mid-sized Midwestern city. And since I cook a lot from scratch I have very little waste. Less than the typical omnivore for sure.

        That said, I can see how under different circumstances it would be easy to generate a lot of plastic waste.

        Either way, this is a great article. I eat almost exclusively vegan but if a friend started raising chickens and offered me some eggs I think I’d have a hard time turning them down.

    I linked over from G+. Earthlings was pretty huge for me. I had no idea about most of those things before I watched the film. Even though it was hard to watch I stuck it out because I felt like I needed to know the truth.

    Awesome blog. I’ve subscribed.

  4. says

    You said that you didn’t notice much of a difference, you should try quitting smoking, a vegan diet and starting to exercise at the same time. I did and for lack of a better term; COWABUNGA! I feel so good.

    Oh, and great blog by the way. :)

      Hi Catherine, thanks for the information about bycatch. I agree with you that both bycatch and the pain that fish feel as they die are important things to consider when deciding how to eat. Also important to consider, I think, is suffering of the small mammals that were killed (in a sense “bycatch”) when the wheat was harvested to make the flour that was in the pancakes we ate this morning ;)

      Thanks I’m enjoying my April challenge – learning about evolution – it’s interesting to know that some of my great great great etc… grandparents were fish :)

    Hi Justin,

    Thanks for posting. It’s thoughts like this that most people never consider. I went through a similar thought process that led me being vegan… although I have never actually watched Earthlings! I just have a few comments I’d like to share, let me know what you think!

    In regards to eating fish; are you eating farmed or wild-caught fish? Farmed fish are raised on “fish factory farms”, crammed together, similar to how chickens are raised. These farms release huge amounts of pollutants into surrounding waters. And wild-caught fish is hurting the oceans biodiversity, and reducing numbers of endangered species from by-catch. Even if you do not take into account a fish’s ability to feel pain and (limited) ability to suffer, the environmental damage done by procuring fish is on some levels greater than other types of meat.

    Regarding Davis’s paper on the number of animals killed to produce food; it is clear that everyone causes the deaths of other beings (although some vegans think they do no harm whatsoever, but they are “out-there” vegans!). Anyways, did you read the original paper by Davis? He used kill numbers from two studies done on crop harvesting; one from sugar cane in Hawaii (http://www.jstor.org/discover/10.2307/3799612?uid=3739568&uid=2&uid=4&uid=3739256&sid=21102303962437), and the other from grain harvest in the UK (http://www.sciencedirect.com/science/article/pii/000632079390060E). There were many small mammal deaths in the Hawaii case (77% killed by harvest) and the UK case (53% killed). In the Hawaii case, the animals were mostly killed by the harvest machines. However, in the UK case, only one out of the 32 tracked mice died from harvest machines; sixteen of the seventeen mice killed were killed by predators (owls, weasels) due to lack of cover. Like you, I think that both the quality of life of an animal and it’s death is important. It seems as if these animals suffer much less than an animal in a factory farm.

    I thought you may be interested in this analysis of the number of animals killed to produce calories for human consumption (http://animalvisuals.org/projects/data/1mc#n1). The analysis breaks down number of deaths into those killed directly and those killed indirectly (during harvest). Unfortunately, it does not include fish, but that is due to how much harder it is to quantify those numbers. It assumes that animals are raised conventionally (in a factory farm). You can see that the number of animals killed can be drastically different for different types of animals. It also does not incorporate the amount of suffering inflicted per calorie; it is a judgement call on this issue, but I would say that the animal industries inflict much more suffering than plant farming.

    Have you thought about how non-food choices affect some of these same ideas (animal treatment and the environment)? Products such as wool and leather financially contribute to the profits of companies that mistreat farm animals. I avoid buying these products because they are so intertwined with factory farming. In addition, leather is treated with a whole range of toxic chemicals to keep it from breaking down. There are several SuperFund sites in the US on old tanneries. (Although, I am not sure the process to create leather substitutes; I should look into this).

    Sorry this is so long, but I had one last thought. Just because a product is vegan, does not make it ethical. My main example of this is the case of palm kernel oil (aka palm oil or palm fruit). It’s cultivation in Indonesia is directly leading to huge losses in the number of endangered Orangutan. This is due to clearing the the rainforest for plantations, and because the Orangutan find palm fruits irresistible; they are often killed if found to be eating the fruits.

    Thanks for your time, and thanks for writing this post. Cheers!

      Hi Brent, great comment. I’ll respond to each thing you mentioned…

      Farmed VS Wild Caught fish: I buy wild caught fish, and investigated the company whose fish I buy and am satisfied that they’re fishing in a sustainable way.

      Davis’s paper: Yes I did read it. Thanks for the additional info – interesting.

      AnimalVisuals article: Thanks for the link. Haven’t read it yet (I’ll get around to it at some point). The chart at the top looks interesting – too bad they left out fish.

      How non-food choices affect animals & the environment: Yes, I’ve thought about this and agree with you that it’s important to consider. I’m more careful about what non-food products I buy now also.

      Vegan products aren’t necessarily ethical: Good point – I agree!

    Interesting article for sure, thanks for posting. Though, I don’t mean to rain on anyone’s parade, but as someone who’s studied various fields of philosophy for years, the vegan ethical claims irk me somewhat. I was here primarily out of curiosity for the health effects of the diet, as I’ve heard widely differing claims. It seems to me that not everyone can actually be vegan, and that some handle it much better than others. Some can’t handle it at all apparently, and they get very sick even eating ‘healthy.’ I believe it’s genetic, as some ethnicities have historically relied largely or exclusively on meat and may be genetically predisposed to a meat-based diet—natives of arctic regions in particular come to mind, as plants don’t grow there at all. All this aside, the dietary evidence I’ve seen points to two facts: one is that there is no one-size-fits-all diet, so I’m instantly wary of any claim of an ideal diet as vegans often suggest. People are too different, and not everybody can be healthy or happy on any given diet. The second is that the diets that are GENERALLY (see point 1) considered the best overall are well-balanced diets that include fruits, vegetables, meats, dairy, et cetera in balance and moderation. The Mediterranean diet and DASH diet are good examples. Though, one thing does stand out to me, that being the evidence that fish is exceptionally good for you—in general. None of this ever seems to be applicable to everyone.

    As for the ethical claims of veganism—I get it. It’s compelling. However, the arguments are entirely emotional in their basis. I seldom ever see an argument for veganism relying entirely on logic, reason, or objectivity. And that’s not to say they’re invalid, but… as a philosophically-inclined person, I understand those arguments don’t hold much weight. Yet, it seems ethically wrong to kill animals or inflict pain, but do we only assume that to be the case because we feel emotionally stirred by it? Isn’t this a case of improperly projecting human values onto non-human entities? What makes anyone so sure pain is always unethical? Perhaps unnecessary pain, but food is pretty necessary, and we’re not technologically or economically advanced enough as a planet to eliminate pain from all food production yet—even plant-based foods. As for pain itself, well, even some plants feel pain, so you’re not going to get very far with that one. Pain is felt by some very, very, very low lifeforms, and I’m not sure you can make the claim that—beyond our emotional inclinations—pain is inherently a bad or unethical thing. What makes anyone so sure the goal of the animal is to live for a long time? Evolutionarily speaking, animals prioritize reproduction and the continuation of the species over individual lives. The same cannot be said of humans. The only two relevant arguments I currently see in regards to this topic are that of evolutionary survival, and that of biodiversity. Neither are hurt, and both are in fact aided by farming and cultivation of animals and animal products. Take, for example, the chicken. Chickens outnumber their predecessors probably a million to one, they’re extremely prolific. Evolutionarily speaking, they’re a huge success. And even if the junglefowl goes extinct in the near future, the chicken will survive for millennia to come. If that comes at the cost of what one might call unethical farming practices, isn’t that still much preferred from an evolutionary perspective? Chickens and humans therefore have a symbiotic relationship—even if farming practices turn your stomach, there are truly much worse things to be found in nature. At least this situation is mutually beneficial for both species.

    As for biodiversity—and tying into the prior statement—people rarely mention the fact that global veganism would bring about the extinction or near-extinction of most of the world’s domesticated species. Is that really better than keeping the emotionally upsetting farming practices? Emotions are subjective, extinction is a cold, hard fact. Domesticated species generally can’t survive in the wild. If sheep are never sheared, their wool grows so dense that their legs collapse beneath the weight, and they die. Chickens have lost the ability to fly, which their ancestors had. They don’t have the same defenses of others flightless birds like ostriches, which can fend for themselves physically. Pigs are much fatter and slower than their wild ancestors were. These animals have all adapted to the farm—that is their natural habitat, regardless of what people feel about the practice of farming on an emotional level. Taking them out of their natural environment will lead to swift deaths. They literally need to be farmed to survive long-term. The solution, then, is definitely not to stop eating animal products. If you don’t like the farming practices in use, the solution is to create a market for whatever you consider to be more ethical farming practices. Only buy meat, eggs or cheese from farms that meet your standards. If such a thing doesn’t exist yet, if you spread enough of an interest in it, it will happen. Though, it already does exist, if you know where to look. Small local farms are usually ideal for that sort of thing, with some being particularly better than others.

    Anyway, just food for thought. I’ve struggled back and forth with this for quite a while myself, as you can see. But if I’m going to do something for ethical reasons, I have to make sure they’re real, rational reasons, and that I’m not contradicting the goal with ‘unintended consequences.’ :)
