The liver accounts for roughly what percentage of body weight?

The liver weighs about two percent of total body weight. In an average adult around 70 kg, that’s roughly 1.4 kg to 1.6 kg, which fits the idea of a large organ but still only a small fraction of body mass. This proportion explains why two percent is the best pick: it’s large enough to reflect the liver’s metabolic demands, yet not so large as to be inconsistent with typical body size. If it were as low as one percent, the liver would be around 0.7 kg, and if it were five or ten percent, the liver would be unrealistically heavy (several kilograms).
