The conscious decision to refuse food or fluids to achieve a goal or set of demands is a hunger strike. Fasting is a method of protesting injustice. From the medical view, in the first 3 days, the body is still using energy from glucose. After that, the liver starts processing body fat, in a process called ketosis. After 3 weeks the body enters a starvation mode. At this point the body “mines” the muscles and vital organs for energy and loss of bone marrow becomes life-threatening. There are examples of hunger strikers dying after 52 to 74 days of strike.
