In short, yes, if she sticks to it. The point of the 'liver
shrinking diet' is just that, to shrink the liver....this is achieved by reducing fat/carb intake so the glycogen (energy) stores in the liver get used up, which also removes a vast quantity of stored water at the same time, as it takes 4 molecules of water to store every one molecule of glycogen. This reduces liver size for ease of access & maneuverability, as the stomach lays behind the liver, and reduces risk of injury to the liver, which could lead to undetected bleeding, thus potential serious complications. Any weight loss is incidental & a bonus.
