Heh, I don't "bother" with vegetables and fruits either...
its no bother to crack open some nuts, bite into a crisp apple, or enjoy some fresh greens.
What happens is, when I constantly eat meat, I start craving plants.
Then when I eat too many plants, I crave meat.
I also think humans are omnivores too. You don't need to know any science just LOOK at a human, do they look like an obligate carnivore? No way, look at our HANDS, the way our teeth and faces are, we look like omnivores...Humans remind me of monkeys, apes, pigs, raccoons and bears, which are all omnivores. We do not have the bodies and stomachs of herbivores, nor do we have the stomachs and bodies or carnivores either (ie. cats digestive systems are different then humans, shorter, more acidic), we are right down the middle, mix and match, anything goes...we are pigs lol
The biggest clue is how our jaws can move from side to side and the way our teeth look, totally different from all mammalian carnivores I know.
Another clue is that humans can live a long time on a vegan diet (a carnivore would not be able to do that)....
Not to say human can't live as carnivore at all...its like with dogs if you know what you're doing you can feed dogs omnivore diet and they will live on it, but they thrive on carnivore because they are carnivore.
It seems to me the people that do well as carnivore are the ones that were eating vegan OR had sugar problems before OR they have no choice (season, location etc). Correct me if I am wrong, but I know of no human that was on a successful omnivore diet that just decided to go carnivore just for the hell of it (I mean long term exclusive carnivore, not "this week I just ate meat cause I wanted to" type of deal). Its always cause they had some issues when eating carbs, but the MAJORITY of healthy people have no issues with carbs, meat or anything paleo, they have issues with eating crap junk foods though. People go carnivore to address issues they had, its like a treatment - and I am not saying that in a bad way at all.
Thats my speculation on the whole carni-omni deal
