Answer 1

Before the modern world, Human body fat is suppose to be a resource for the body to use when there’s an absence of food during hard times, like winter. Fat is just stored energy for later use. Water is more important. 3 days without water/a hydrating liquid, you’ll be dead. Having 31% body fat and a good supply of water, you’ll live for a few weeks.
