I used to know one. She used to be fit but then had a baby and gave up. (Pathetic.) I took her off my facebook feed because one of my friends asked her if she had some spare vegetarian recipes (since she likes to  cook at home) and she said "hur derp-- does bacon count as vegetarian?" And we were both like even if you're not a vegetarian, there's no need for that. I know plenty of omnivores who still eat mainly plant based. Then bacon became her thing. i bet she's fatter now...
