The Rapid Loss ‘Fullness’ Shake has everything you would expect from the best Meal Replacement Shake, but with a very important twist. Rapid Loss is so much more than just an ordinary meal replacement as, for the first time; it also includes an ingredient that works on the same principle as gastric band surgery. By making you feel so full you simply can’t eat as much, Rapid Loss automatically lowers your calorie intake, reducing the need for willpower.
