Meat-eaters, also known as carnivores, are individuals who primarily consume meat as their main source of protein. Another synonym for meat-eaters is "carnists," which is derived from the Latin word for flesh. Some vegetarians or vegans may refer to meat-eaters as "non-vegetarians" or "omnivores," as they consume both plant-based and animal-based foods. The term "pescatarian" can be used to describe individuals who consume fish as their primary source of protein, while "flexitarians" are individuals who consume meat in moderation and primarily focus on a plant-based diet. Lastly, the term "carnivorous" describes animals that consume meat as their primary source of nutrition.
