I'm not a very good one yet. I still eat stuff that's tainted with meat (e.g. baked beans) and about once a week I even eat a meal that contains meat because the vegetarian or fish options available suck. That's ok, though, because it's still compatible with my reasons for changing my diet.
I know it's amazing that I've given up all of the following: hamburgers, Thanksgiving turkey, a nice juicy steak, and even bacon. I've made the change for health reasons. I was inspired by Thu, who has already lost 25lbs partially due to diet changes, and my own lack of weight loss from shall diet changes combined with moderate exercise. Pescatarianism seems like a good compromise too. I really like fish and some studies show evidence of health benefits.
There's a lot going against me, though. Winnie hates fish and loves meat. I also love bacon. vegetarian and pescetarian friends have told me that the meat cravings go away, but I always figured this was confirmation bias (since I never discussed this with my friends who tried vegetarianism and gave up on it).
I decided to give it a shot. It's been about a month now and I'm already observing some positive health benefits and I'm enjoying food just as much. I've already lost 5 pounds, which is not an amazing feat, but I've done it while eating ice cream and exercising less. The rate of weight loss is still accelerating too. I bet I'll lost at least another 5 pounds before I reach my new steady state.
Unlike other diet changes, where I gave something up and replaced it with nothing, I seem to be filling my diet with food I enjoy almost as much as meat. I'm eating more deserts and drinking more beer. It seems that meat was, by far, the highest calorie density part of my diet. Best of all, I'm eating sushi like every week now.
Lets see how long I can keep this up before the bacon monster reclaims me.
