The human body is remarkably resilient, but when food intake is severely restricted, it initiates a series of survival mechanisms. This process moves from using readily available glucose to breaking down fats and, eventually, muscle tissue, demonstrating a profound shift in metabolism to conserve energy.

Records exist of individuals surviving without food for several weeks, with one of the most famous cases being an obese patient who lived for over a year under medical supervision. This incredible resilience leads to the critical question: how long to live if there is no food? The answer depends on crucial factors, including hydration and initial body fat reserves.
