What might prolonged fasting result in for the body's systems?

Prolonged fasting can lead to disruption of thermoregulation due to several physiological changes that occur when the body is deprived of food for an extended period. When fasting, the body's metabolism slows down as a survival mechanism to conserve energy. Additionally, the lack of food intake can affect hormone levels, such as those regulating body temperature, including thyroid hormones. This disruption can lead to an impaired ability to maintain a stable internal temperature, making the body more susceptible to fluctuations in environmental temperatures.

In contrast, prolonged fasting does not typically result in increased energy levels because the body is running low on fuel sources. Similarly, while fasting may impact muscle recovery due to insufficient nutrient intake, it does not generally lead to enhanced muscle recovery or stable bone density, as both processes require adequate nutrition for optimal function and maintenance.
