When you go without food for a while, your body goes through several physiological changes to adapt to the lack of nutrients. Initially, your body will use up the energy stored in the form of glycogen in the liver and muscles. This glycogen serves as a quick source of energy.
However, once this glycogen is depleted, which typically happens within 12-24 hours, the body starts breaking down fat stores to provide energy through a process called ketosis.
Ketones, which are byproducts of fat breakdown, become the primary fuel for the brain and muscles.
After a prolonged period of fasting, the body enters a more energy-conserving mode. Your metabolism may slow down, and this can result in fatigue and a feeling of weakness as the body tries to conserve remaining resources. Prolonged fasting can also lead to muscle breakdown, as the body begins to use protein for energy, which can result in muscle loss and a decrease in muscle mass.
In addition to metabolic changes, a lack of food can impact your blood sugar levels. Low blood sugar (hypoglycemia) can lead to symptoms like dizziness, irritability, confusion, and difficulty concentrating. Without adequate nutrition, the immune system can weaken over time, making the body more susceptible to infections.
Overall, the effects of not eating for extended periods depend on the duration of fasting, the individual’s overall health, and the amount of body fat and muscle mass they have. While the body can survive for a limited time without food, prolonged periods without nutrition can have serious consequences, including organ damage……READ ORIGINAL & FULL CONTENT HERE
