Answer 1

Everyone is talking about nutrition, but I am pretty sure drinking 2,000 calories of oil, or even just 1,500, would act as a pretty extreme laxative, resulting in you becoming dangerously dehydrated long before malnutrition became a concern. Remember the rule of 3, you can survive 3 minutes without air, 3 days without water, and 3 weeks without food. Water is a far more pressing concern, don’t mess with your ability to absorb it.
