Like, I do think in an ideal world everyone would be vegan and all animals would be free not to be our food...
...Buuuttt I've been eating their products for my entire life and they constitute the vast majority of my favorite foods/drinks and foods/drinks I just like in general, and am thus unwilling to give them up even if I know it would be the better thing to do.
I mean, I probably could if I really, really wanted to, but I just don't want to.
Losing weight can be really hard and being obese is WAY more of a risk factor than eating meat for heart attacks. Don't be an idiot.
Anecdata: I lost 100 pounds in the first year of being vegan, with no other lifestyle changes.
