The body stores fat for the exact purpose of surviving limited access to food. Most Americans could go weeks without eating, and they'd be mostly fine. Sudden refeeding is an issue, of course, because of electrolyte balance. But we have a misunderstanding of how long the body can go without food, by design. What we mainly need is water during periods without food. After about 3 days without food, the body stops telling you your hungry and switches to fat metabolism.
