I probably should have clarified a bit more, so here it goes.
TL;DR: Going vegetarian and losing weight had nothing to do with one another, but have combined to really change the way I eat.
I have known for a long time that a vegetarian diet was better for the environment, and then early this year I heard a story from a family I served (I had funeral services for their dad) that really drove home ethical points about eating meat that I also pretty much knew in the back of my mind anyway. So all year I had been cutting back on meat, mainly with our four HelloFresh dinners each week. Started with some vegetarian choices here or there, then a solid 2 or 3 a week, and then usually all 4 most weeks.
It was Aug. 15 I think that I hit 270lbs and started losing weight. Then at the end of August I decided, completely unrelated to that, to try and give up meat completely. It has thus far worked out and I am now a month and a half without meat. But while my diet is about losing weight and being healthier, my going meatless is 100% environmental and ethical.
Getting specifically to Beyond Meat, I will say I wasn't looking for that. We have enjoyed finding good recipes that just don't use meat, but Beyond Meat opens things up, especially when other people are involved. The biggest success was having the in-laws over and cooking burgers, and having my father-in-law, who is the furthest thing from a vegetarian you can imagine not only loving the Beyond Burgers and complimenting them, but going so far as to have the second with no condiments or bun, just straight patty to enjoy how good it was. It allows us to occasionally just cook how we used to more easily when we want, and cook for others more easily without worrying they'll be turned off at all.
I've personally never cared if something is processed, and compared to meat at least their formula seems plenty healthy to me. My only real gripe with the company is that they claim to care about the environment and yet proudly talk about how they don't have GMOs, which have the ability to be more environmentally friendly and feed more people.
