what will happen if you dont eat for 72 hours?

 

 If you don’t eat for 72 hours (3 days), your body undergoes several metabolic and physiological changes. While most healthy individuals can survive a 72-hour fast without serious harm, here’s what typically happens:

---

0–24 Hours:

• Glucose depletion: Your body uses up stored glycogen (stored form of glucose) in the liver and muscles for energy.

• Mild symptoms: You may feel hunger, irritability, low energy, headaches, or dizziness.

• Insulin drops: Insulin levels fall, and the body starts shifting to fat as an energy source.

---

24–48 Hours:

• Ketosis begins: The liver starts producing ketones from fat to provide energy to the brain and body.

• Increased fat burning: Fat becomes the primary energy source.

• Muscle breakdown: Some lean tissue is broken down to provide amino acids for essential functions.

• Mental clarity or fog: Some people report improved focus; others feel sluggish.

---

48–72 Hours:

• Deepened ketosis: Ketone levels increase significantly.

• Autophagy ramps up: The body may intensify the process of breaking down and recycling old or damaged cells—a potential benefit of fasting.

• Muscle preservation attempts: Growth hormone levels may increase, which helps preserve muscle mass.

• Electrolyte imbalance risk: Without food (or supplements), potassium, sodium, and magnesium levels may drop, leading to cramps, heart palpitations, or weakness.

---

Risks:

• Dehydration: Especially if you're not drinking enough fluids.

• Electrolyte imbalance: Can become serious if not managed.

• Low blood pressure or blood sugar: May cause fainting or dizziness.

• Exacerbation of medical conditions: Especially in diabetics, people on medications, or those with chronic illnesses.

---

Who should not fast for 72 hours:

• Diabetics (especially on insulin)

• People with eating disorders

• Pregnant or breastfeeding women

• Those with chronic illnesses

• Individuals under 18 or over 65 (without medical supervision)

If you're considering a 72-hour fast:

Make sure to:

• Stay hydrated (water, electrolytes)

• Avoid intense physical activity

• Break the fast gently (start with light, easy-to-digest foods)

• Consult a doctor if you have any medical conditions
