What is flexitarian? Take Away English|BBC Learning English
A flexitarian diet involves eating plant-based foods and only occasionally eating meat and fish. You might think this is a halfway house to being a vegetarian by not completely abstaining from meat. But if vegetarianism is hard to swallow and you fancy chomping on the occasional lean steak, then this could be the choice for you.
This eating style allows you to supplement some ingredients that you wouldn't get in a stricter vegan diet – another trend growing in popularity. And like veganism, flexitarianism isn't about eating carefully to help you lose a few pounds - it's something people choose for ethical reasons, to help the planet. And a study into the global food system and how it affects the climate, has found that eating mainly plant-based foods is one of three key steps towards a sustainable future for all by 2050.
