Is it possible to go vegan if you love meat?

I was vegetarian for a decade, then pescetarian for over a decade, and started eating meat again quite recently, when I started craving it badly on starting strength training.

I am fully aware of what goes on in the slaughterhouses, but also aware that this is not going to change because a small % of the population shun meat and dairy. In fact, I could almost think of it as my being wasteful of the horrible death these animals did suffer, by avoiding the product. As it is, a load of meat goes to waste, so in essence, that animal suffered and died needlessly because no-one consumed the end product. There are many ways to view the ethical and moral side of things, I suppose. If I were in the position, I would hunt my own food and use every part. As is, I aim for free range, organic, grass fed etc.

I've been a vegan for over 7 years so I'll add my opinion

To address your specific questions:

Soup: use vegetable broth (a low sodium variety!) and to make it creamier you can add soy milk soy creamer, almond creamer, coconut cream, rice cream, hazelnut cream, etc... You could also soak and puree your own nuts to make a "cream" or even just add in a pureed potato (I make a yummy "creamy" soup with just broth, sweet and white potatoes leeks, carrots, and onions)

Milk substitutes: soy, almond, coconut, hemp, rice, etc... Tons of possibilities! There are good vegan cheese options too (daiya, tofutti, teese, etc) and omgggg there are some amazing ice creams. I also eat vegan yogurt, either coconut milk based or almond milk based.
Egg substitutes: vary depending on the use of eggs (scramble, baking etc) but they are all out there and easy to find too!
Meat: There are so many options! You can go for packaged products like Boca or Gardein (which I love!) or more whole products like seitan, tempeh, tofu, etc. As you gain experience with plant-based meals you'll stop thinking of meals as the traditional "animal protein+sides" and get more creative too. Keep in mind all food has protein so instead of having a slab of meat you can have roasted veg+chickeas+quinoa and more than fill all your requirements!

Supplements: I've only rarely had to take supliments and never for reasons related to veganism. I had to take iron supplements as a teenager but anemia ran in my family (of omnivores) and since then I have gotten more than enough iron from my diet. Other than that I take a multivitamin when I remember but that's it. People will try to scare you about protein or B12 but if you eat a healthy balanced diet that includes some enriched foods you'll have no problem.

Expense: Like any diet, it depends on what you buy. If you purchase whole foods and cook from scratch it's so cheap (think about what the poorest people in the world eat, it's rice and beans usually!) In that case, veganism usually works out cheaper than an omnivore diet because eggs/milk/cheese/meat are expensive. If you opt to buy more organic food or packaged and prepared foods it will be more expensive of course but still favourably comparable to an omnivore's grocery bill. If you meal plan then you can save a lot on groceries by not wasting perishable produce.

In terms of liking meat, I used to but I didn't think that a superficial desire like taste was worth the pain eating animal products caused. I have no desire to eat meat at all these days. My husband is still an omnivore and is completely satisfied by the vegan dinners I cook at home.

If you're interested you can look into the movies Forks Over Knives and Vegucated for more info on vegan diets (Vegucated is great for a lot of the questions you had and shows meat-lovers trying out veganism). There's a good website on fitness and veganism called http://veganbodybuilding.org which you might want to check out too? If you want cookbook suggestions just let me know what you like and I can tell you some of my favourites.

Hope that helped! Let me know if you have any more questions!
