How long can a person live with only eating one quarter cup of ice cream and drinking 4 to 6 ounces water if they weigh 105 lbs?

It is not possible to survive on such a restrictive diet. A person needs a balanced diet of carbohydrates, proteins, fats, vitamins, and minerals to stay healthy. A diet consisting solely of ice cream and water would lack many essential nutrients, leading to malnutrition and eventually death.
