Liquid-only master cleanse: the wrong direction?

You may have heard of the "Lemonade Diet" that requires a bunch of beverage drinking and very little eating. Sounds like a plan to many of us, but to those knowledgeable about daily nutrition needs, the method immediately becomes suspect.

Does it work? For losing weight, sure (for many). For human health, I remain quite skeptical. But hey, in the age of immediate gratification, having weight loss yesterday is sometimes more important than actual health.

Once you see how many toxins are in everyday foods (mostly processed and fast foods), I agree with the Master Cleanse Detox Diet author that cutting back on these items (or jettisoning them completely) is a great way to return to health. But a liquid-first diet? Not sure about that unless you just puree all that normal, healthy food in a blender. What are your thoughts?
