Yeah, any diet you choose is a “thing” and don’t worry if it doesn’t have a name hahah. I don’t think it’s considered vegetarian by most people; I think the closest term you’re looking for is “flexitarian” which is loosely defined as someone who eats vegetarian sometimes.
If you wanted to sign up for the challenge for january though as that, feel free! It’s still cutting meat out of your diet and it can still be challenging! —Carolyn
