What was considered to be the cause of Chris McCandless's death?

• A. Starvation
• B. Hypothermia
• C. Poisoning
• D. Dehydration

Answer: (A)

In this situation, the underlying issue is not having enough calories to meet the body’s energy needs. When someone in a survival setting cannot obtain adequate food, the body first uses stored fat, then breaks down muscle, and eventually systems fail because essential energy and nutrients are missing. In Chris McCandless’s case, his prolonged caloric deficiency in the harsh Alaskan environment led to a gradual physiological breakdown and death from starvation. While cold exposure can worsen conditions by increasing energy demands, it acts as a contributing factor rather than the direct cause here. There’s no evidence of poisoning, and while dehydration can accompany starvation, the core problem remains the insufficient caloric intake.
