First world problems; there is so much food that we can make lifestyle choices around it. You can pretend to be a caveman and eat "paleo" since meat is neatly wrapped in plastic at the store and you didn't have to hunt it down. (And if you study the Hadza tribe who are one of the last paleo-bros on the planet you'll find that meat is a small part of their diet). You can forgo certain meats and call your self pescatarian since you can find fish in the middle of a city. And you can intermittently fast since you know that you can quit anytime and stuff yourself full of food.
We as a modern society have to be the most smug of all. Think about every predator in the world. We constantly pay to exercise, to burn off EXTRA calories, where as every other animal on the planet conserves them or expends a vast amount to obtain more.
