Around the holidays there's typically a lot of food pretty much everywhere you look. From holiday parties to family dinners to the endless cookies, it's unavoidable. That's why Chloe Moretz announcing a huge diet change right now is pretty impressive, because the temptations are endless.

On Twitter, Chloe announced that she's becoming a vegetarian. She said she's pretty much eliminated all meat from her diet, but she still sometimes eats fish so she's not totally there yet. Even though it must be hard to do this time of year, Chloe said it's the best thing she's ever done.

"Going vegetarian was probably one of the best decisions I've ever made," Chloe tweeted.

She then got deeper into the details of her dietary restrictions, noting that in addition to eliminating meat, she's also dairy-free. That would make her semi-vegan, but Chloe still eats fish sometimes. Technically, Chloe says she's a pescatarian, but the goal is to eventually eliminate fish too.

According to the American Heart Association, going vegetarian can reduce your risk for all kinds of health issues. Studies have shown vegetarians typically have a lower risk of diabetes, obesity, coronary heart disease, and more. Vegetarians do have to be careful, though, to plan their food intake so they're getting all the nutrients you would miss out on without meat. That includes iron, protein, B-12 and others.

The American Heart Association also warns that going vegetarian alone isn't enough to keep you healthy. You can be vegetarian and eat nothing but tofu and Doritos, and that's not so great. Like we mentioned, a vegetarian diet has to be planned so you're consuming the right kinds of foods to give you proper energy and nutrition.

Since Chloe seems so happy with her dietary changes, it's safe to say she's probably doing vegetarianism (or pescatarianism) the right way. Congrats to Chloe for doing something that makes her happier and healthier!
