Is it possible to live off of a meal replacement powder like Myoplex?

A liquid diet isn't impossible by all means, but if you're considering doing what "The Rock" did in his new movie where he is a dad, by blending fish and other stuff together, I'd say go for it. Our body doesn't need to actually CHEW something, per say, but it does need all the nutrition that we get from eating the things we usually do. Just make sure you are DRINKING a balanced diet of nutrition, protein, vitamins, fiber, etc. Just because V8 says it "has everything you need" doesn't necessarily mean it's going to sustain your body. good luck.
