I did a liquid diet once called the Cambridge Diet. I also tried Slim-Fast as meal replacements. I weighed around 145 when I did the first one and about 160-180 all the times I tried the second one.
Here I am over 200 and trying to get back
down to my previous high weights.
Do drastic, simplistic "I just won't eat!" diet plans work in the long run? You do the math. But I think you know that even though you posted here. I'm afraid you won't find much appreciation for your chosen plan, although if you decide to go with a more realistic, livable plan, you'll certainly find plenty of support here.
There are a lot of ways to get you where you want to go: low-carb, counting calories, Weight Watchers, Ideal Protein, some vegetarian/vegan plans, you name it. I have yet to see a poster here who lost significant weight or maintained a weight loss on any liquid diet that was not medically supervised like Oprah and her Optifast back in the late 80s.
Oh, yeah--and Oprah regained the weight she lost from THAT, too--even though she's rich and had a cadre of doctors helping her. That's how well liquid diets work long-term.
