>Why would your body breakdown your organs when you still have plenty of adipose stores ?

Most people are not "fat adapted" meaning their body/brain primarily run off of glucose.

When you fast and your body runs off of glucose, it still goes into ketosis and burns fat, but the brain still needs glucose because that its accustomed primary fuel source (think of marathon runners hitting the wall, that is their body conserving remaining glucose in the body for the brain to function). When their is no dietary glucose the body breaks down protein (muscle and organs) to convert into glucose to keep the brain working (gluconeogenesis).

This will still occur but to a far lesser degree to people who are fat adapted and primarily use fat for energy.
