Real men may not eat quiche, as the 1980s book informs us, but they clearly can be vegetarian. And even the manliest of men at that. The Norwegian Armed Forces announced that it plans to put troops on a vegetarian diet once a week.

Armed with the knowledge that livestock farming accounts for 18 percent of greenhouse gas emissions worldwide, according to the UN Food and Agriculture Organization, the country’s defense ministry decided to make Mondays meatless.

"It's a step to protect our climate. The idea is to serve food that's respectful of the environment," spokesman Eystein Kvarving told AFP.

The new plan has been initiated at one of the main bases, and will soon be introduced to the rest of the stations, including its international units. The army estimates it will slash meat consumption by 150 metric tons per year.

"It's not about saving money," said Kvarving. "It's about being more concerned for our climate, more ecologically friendly and also healthier."
