It's never been truer that we are what we eat. The next time you’re at a dinner party and someone identifies themselves as a climatarian, don’t look shocked.

1. Become a climatarian A climatarian is someone who eats with climate change in mind, generally by cutting out food whose cultivation contributes to global warming. Here's how The New York Times defined the term in its list of new food words from 2015: CLIMATARIAN (n.) A diet whose primary goal is to reverse climate change. This includes eating locally produced food (to reduce energy spent in transportation), choosing pork and poultry instead of beef and lamb (to limit gas emissions), and using every part of ingredients (apple cores, cheese rinds, etc.) to limit food waste.

The New York Times published its list of the top new food words for 2015. Words and phrases that made this year’s list range from “beer o’clock,” one’s personal assessment of the right time of day to start drinking, to “hangry,” the state of being so hungry that you become angry or irritable. But, the one word most relevant to the environmentally conscious is “climatarian.” The New York Times defines it as “a diet whose primary goal is to reverse climate change. This includes eating locally produced food (to reduce energy spent in transportation), choosing pork and poultry instead of beef and lamb (to limit gas emissions) and using every part of ingredients (apple cores, cheese rinds, etc.) to limit food waste.”

If you try to eat locally sourced food, limit food waste, and avoid the most energy-consuming of meat products, your CO2-conscious dietary habits may have earned you a new label: “climatarian.”

Climates is calling on meat eaters to make their New Year resolution to ‘go climatarian’ for an easy way to make a big impact on climate change and help save paradise island communities from extinction.

As conservation charity WWF launches its new LiveWell range of 'sustainable' meals. Edie.net notes that 'LiveWell is not the first campaign to attempt to reduce the environmental impact of people's food choices. Earlier this year Climates - a new environmental social networking site - launched its Climatarian diet which it claims can save up to a tonne of CO2 per year for each person.'

Climatarian, a diet designed to help meat eaters cut their carbon footprint, could also help tackle world hunger and achieve United Nations’ sustainable development goals (SDG).

Climate change is probably not uppermost in your mind as you stuff your face, but there is now a diet that benefits not only your health but also the planet. Might you consider going climatarian?

Climates and the Climatarian diet was the topic of discussion with Harriet Scott and Tim Arthur on BBC Radio London.
