Anecdotally I'm the opposite. I personally know dozens of meat eaters who have had major health problems because of their diet.

A varied diet is often promoted because it gives you the most chance of getting the nutrients your body needs, but it fails abysmally when it comes to excluding things your body doesn't need.

If you also start to consider the environmental impact and animal abuse that comes from 'just eat everything', then it becomes very compelling to put a small amount of effort into reducing meat/dairy consumption and aiming towards a whole food plant based lifestyle. Small steps aren't difficult for most people.
