Vegetarianism: it's cited as a sure-fire way to lose weight, live longer AND help the environment.

But not all veggies are created equally, it seems. 

In fact, an alarming number of herbivores are actually tucking into meat-treats while drunk.

The exact number? More than ONE THIRD.

Yes, 37 percent of vegetarians in one recent survey admitted that they're not so strict once they've had a few drinks.

The study, carried out by VoucherCodesPro and involving some 1,800 respondents, also discovered that the most popular cheat for wayward vegetarians was kebab meat, followed by burgers, rashers, fried chicken and sausages.

Although, an astonishing seven out of 10 never disclose their indiscretions to others.

VoucherCodesPro boss George Charles said in response: "It's important for friends of these 'vegetarians' to support them when drunk and urge them not to eat meat as I'm sure they regret it the next day."

Previously, another US-based study showed that American vegetarians are just as bad: 84 percent of them stray on ocassion too.
