Americans eat as much meat as ever, preparing beef and chicken at home at least four nights a week. Yet consuming less meat is one of the best ways to reduce the environmental impacts of our food, commonly known as our foodprint. And while adopting a vegetarian diet is one approach, some people may find this choice extreme or overwhelming.

But are you aware of other reduced-meat movements, like reducetarian, demitarian, and flexitarian? Any of these options can help you reduce the amount of meat you eat at a pace that feels more comfortable than giving up meat outright.

What Is a Reducetarian Diet?

If you’re at the beginning of your journey to reduce the amount of animal protein you consume, a reducetarian diet might be a good choice.

Movement founder Brian Kateman coined the term as a way to carve out a space for people who want to “go at their own speed […] instead of diving headfirst into plant-based eating.” With a reducetarian diet, “the act of trying is encouraged,” which means the diet is not dietarily or morally restrictive.

“Anyone making small, positive changes to their diet is a reducetarian, and that’s something we should celebrate,” Kateman says.

Because reducetarians naturally go at their own pace, the climate or carbon impact is unclear and depends on individual commitment. That said, regular reducetarian choices make a difference; for example, choosing a soy- or pea-based burger can mean as much as 87% less water, 96% less land, and 89% fewer greenhouse gas (GHG) emissions than a beef burger.

What Is a Demitarian Diet?

If you’ve been regularly looking for plant-based alternatives, you might already be a demitarian even if you didn’t know about this label before.

A demitarian is someone who makes a conscious effort to reduce their meat consumption for environmental reasons. A recent UN report applied the term to mean the practice of halving your meat and dairy consumption. It found that if Europeans halved their meat and dairy consumption, “harmful greenhouse gas emissions from the continent’s agriculture would fall by between 25% and 40%.”

If you’re looking to cut down on your consumption of the most carbon-intensive meats, some choices result in more carbon impact than others. Cattle raised for beef create by far the most GHGs at 59 kilograms of CO2-eq per kilogram of beef — roughly, 130 kilograms of CO2-eq per pound. This is over two times the carbon footprint of the next most carbon-intensive meats, lamb and mutton. These are followed closely by dairy cows, which means eating less cheese is also a foodprint-friendly choice. Farmed shrimp and fish as well as poultry also have a significant carbon footprint, but it is much lower than that of the ruminants.

What Is a Flexitarian Diet?

A flexitarian is a person with a primarily vegetarian or vegan diet who also occasionally eats meat, fish, and dairy. Flexitarians, as the prefix suggests, are “flexible” in their approach and may make exceptions for occasional dietary or cultural reasons (like health needs or travel).

We might compare flexitarianism to the inverse of “Meatless Monday”; instead of going without meat one day a week, a flexitarian might consume animal protein once a week. This diet can also help people who want to transition to a vegetarian diet avoid the pitfalls of going full-force, and then finding it difficult to maintain.

If vegetarians can expect to reduce their CO2 emissions by 3% to 30%, flexitarians should expect slightly smaller carbon savings, but significantly more than what demitarian and reducetarian diets save.
