If you’re a former vegetarian who’s back to eating meat, you’re not alone. A recent study by Psychology Today reveals that most vegetarians fall off the wagon occasionally. Some of them do a permanent 180, and turn into complete carnivores. Why? Partly because sticking to a strict vegetarian or vegan diet is tough, and partly because people who gave up meat for ethical reasons have found “humane” ways to eat meat again.

Like one 29-year-old man we read about. He became a strict vegetarian at age 12, boycotting companies he believed were mistreating animals. He even had the word “vegan” tattooed on his neck. Today, he’s an “ethical butcher,” and believes that educating customers about organic, humanely-raised, grass-fed animals is the best way to protest animal cruelty.

If you’re a former vegetarian who’s back to eating meat, know this: Words on food labels like “natural,” “organic,” “certified humane,” and “cruelty-free” mean different things to different people. Like “free-range” to you might mean a calf raised in a huge, green pasture, while “free-range” to them might mean 10 minutes outside a cage a day.
