Input: Consider Input: Question: Does the methionine-choline deficient dietary model of steatohepatitis exhibit insulin resistance?
Answer: GTT, ITT and QUICKI confirmed the absence of insulin resistance in the MCD fed mice. This model causes fibrosing steatohepatitis and may help delineate the non-insulin resistant mechanisms involved in human steatohepatitis.

Output: no
