Liquid Meal Replacements, as part of a calorie-controlled diet, have actually been found to be quite successful for weight loss and weight maintenance.  In fact, Slim-Fast has 45 clinical studies to show it's success.  If you wish to view the abstracts for these studies, go to: www.medical.slim-fast.com/page_3_0.asp.  

Please note that the Slim-Fast 3-2-1 Plan is not a total liquid diet.  Total liquid diets should only be followed under strict medical supervision.

Hi i was reading in a book called burn the fat feed the muscle and in the book it says that liquid diets or diets that have you drink mostly shakes are not healthy. The book says that when people  eat mostly liquids they lose out on the thermogenic effect that solid food has. Also, it says that the human body's digestive system is not desinged to have mostly liquids.
