After about 12 to 24 hours without food, your body switches gears into what’s called ketosis. It starts breaking down stored fat to create energy, producing molecules called ketones.

This process helps you survive longer periods without food, but you may experience headaches, fatigue, and difficulty concentrating as your body adapts.

If you continue not eating for several days, your body starts breaking down muscle tissue for energy. You may feel extremely weak, mentally foggy, and emotionally drained.

Over time, the lack of nutrients can damage organs and suppress your immune system, making you more vulnerable to illnesses.

Listening to your body and providing it with regular, balanced nourishment is key for maintaining both physical and mental health.
