I say NO to any liquid or extreme diets. What is the hurry?! There isn't any reason to rush.
Drastic calorie reductions reduce muscle mass, metabolism, heart strength, etc. And can cause gallbladder
and liver damage extremely quickly (i.e. in DAYS in some cases!).
If you do feel the need to lose weight, just eat reasonable portions of reasonable foods, and do as much exercise as you can reasonably do. That is good advice in any case and for any weight.
