When I first wanted to eat less meat, I began with meat-free Mondays. It was easy enough — just one day out of seven — and I started finding simple vegetarian meals I could make after work. Next, I tried going meat-free on weekdays, reserving my pork dumplings and grilled salmon for weekends. Eventually, I went pescatarian, then totally vegetarian for a little over a year.
At the moment, I'll eat meat when I'm dining out or ordering in, but don't buy it from the grocery store or cook it at home. Life is constantly changing, so it makes sense that your food choices will too; don't beat yourself up if you can't give up meat all together, or do, then go back to eating it again — it's fine.
