I was vegetarian for several years. I tried going vegan 3 times. I did plenty of research on a balanced diet and did it slowly so my body could adjust. Each and every time, my body couldn't handle it. My skin was dreadful, my iron levels plummeted and my blood pressure always got higher. I love cooking so was making lots of lovely vegan meals from scratch but my body still couldn't handle it. In the end, my body started craving meat like crazy so I gave in.
Now, I eat local, high welfare, grass fed meat from a nearby butcher, and organic dairy.
I don't eat a ton of meat (rarely have it for breakfast/lunch), mostly for dinner and honestly, find half a chicken breast sufficient for me. They're huge though, and not pumped full of water than shrinks on cooking. Not massively bothered about cheese or eggs, though I do enjoy them when I do eat them. I do, however, love yoghurt, proper butter and chocolate so I'd struggle to give them up. I love a lot of foods that happen to be vegan - peanut butter, falafel, hummus, homemade bean burgers, chickpea and mushroom curry.
In theory, I love the idea of being vegan but I've tried several times and it just doesn't work for me. So I do try to minimise the amount of meat/dairy I consume but wouldn't do it completely.
