Ukrainian model Valeria Lukyanova became crazy-famous in 2012 for undergoing insane amounts of plastic surgery to look like a live version of a Barbie doll. But now, the model claims she has a new strategy for maintaining her shape: She recently told the International Business Times that she practices a diet called Breatharianism. How it works: Rather than eating and drinking food and water (like a human), you "live off of" air and light, otherwise thought to be "cosmo micro-food" absorbed from the environment.

Just to be TOTALLY CLEAR: This is complete and total nonsense and also incredibly dangerous. Anyone who tries it could literally starve to death (not to mention, forgoing water can lead to a very rapid death via dehydration). That's why the British Dietetic Association roundly condemned the Breatharian diet in December for not providing the essential nutrients and fuel you need to stay healthy. Yeah, we'll say. (Check out the other top five celebrity diets that don't work.)

Ultimately, what Lukyanova is describing is nothing more than a glorified eating disorder, and we hope that she gets the help she needs to stay healthy. In the meantime, for anyone who is hoping to maintain a certain weight or lose weight in a healthy and sustainable way, our best advice is to make healthy eating a lifestyle choice. Load up on nutritious and nutrient-dense whole foods, and minimize the amount of processed foods you take it. Eat plenty of fruits, veggies, and nutritious sources of protein and fiber, and drink lots of water (try these 10 tricks to boost your water intake).
