Final answer:
Morgan Spurlock's liver likely experienced damage resembling fatty liver disease due to his 30-day McDonald's diet, highlighting the potential risks of frequent fast food consumption.
Step-by-step explanation:
The question is regarding the health impact of eating exclusively at McDonald's for a period of time, similar to what was documented in the 'Super Size Me' documentary.
While the exact changes to Morgan Spurlock's liver are not described in your excerpts, it is known from the documentary that Spurlock experienced a significant deterioration in his health, including liver damage that resembled non-alcoholic steatohepatitis (NASH) or fatty liver disease as a result of his 30-day experiment. Such dietary habits lead to the accumulation of fat in liver cells, causing inflammation and potential damage to liver tissue.
Consuming fast food frequently, high in calories, saturated fat, sugar, and salt, but low in nutrients, could potentially lead to harmful health effects such as obesity, diabetes, cardiovascular disease, and liver issues.
