Water is an essential molecule for our life, which plays a fundamental role in numerous biological processes. However, comprising about 60% of the human body, it serves as a solvent for biochemical reactions, regulates body temperature through sweating and respiration, and transports nutrients and waste products throughout the body. Besides, this human biology, water is vital for ecosystems, serving as a habitat for countless species and playing a crucial role in maintaining biodiversity.
Also, its unique properties, such as high surface tension and thermal stability, contribute to its significance in shaping the Earth’s climate and geography.
Also, did you know that allowing access to clean water is a global challenge, with millions of people lacking safe and reliable sources, underscoring which is importance of conservation and sustainable management practices?
However, if you are planning for the Three-week water fasting then this article is for you. Water fasting for 21 days is an extreme fasting protocol and is rarely advisable for all.
A 21-day water fast is a 3-week water fast, which that means for 21 full days, you will only consume water, non-caloric beverages, and electrolytes, but no food or calorie-containing beverages. No carbs, no protein, no fats, no anything! Isn’t it difficult?
What Is 21 Day Water Fast?

Prolonged fasting can be safe but it is not examined water fasting for such a long period, 21 days.
Water-only fasting for 21 days may result in adverse health and metabolic change and also side effects such as dehydration, a loss of lean muscle mass, hyperuricemia, hyponatremia, protein-sparing, sodium and potassium-sparing, decreased serum calcium and magnesium levels, and acidic urine.
Even shorter water fasting for 2-3 days periods can lead to symptoms such as headaches, nausea, vomiting, constipation, the inability to regulate body temperature, muscle loss, lightheadedness, shakiness, poor healing, blurry vision, difficulty sleeping, mood instability, and dangerous nutritional deficiencies.
21 days, water fasting would be neglectful and potentially dangerous not to make it abundantly clear that a 21-day water fast is contraindicated for most people and should never be attempted without medical clearance, guidance, and proper medical supervision.
However, there are usually healthier, less severe alternatives for water fasting for 21 days for weight management and perceived health and wellness benefits, including shorter fasts, an intermittent or alternate-day fasting diet, and a well-balanced diet and exercise program if it is done with a good diet plan.
Even in some cases, doctors would approve for this to try 21-day water fasting, you need to work closely with your provider during and afterwards to ensure that your body is handling the prolonged abstinence of caloric intake.

What happens if we do 3 Week Water Fast for our body?
Initial Phase (Days 1-3):
- Glycogen Depletion: Your body uses up stored glycogen (the form of carbohydrate stored in the liver and muscles) for energy. This can lead to fatigue, irritability, and headaches.
- Hydration: You might experience increased thirst and the need to drink more water to stay hydrated.
- Ketosis: As glycogen stores are depleted, however, your body begins to enter a state of ketosis, where it starts breaking down fat for energy. This process can cause bad breath, dry mouth, and a metallic taste.
Intermediate Phase (Days 4-10):
- Increased Ketosis: Your body relies more on ketones from fat for energy. You may experience decreased hunger and a more stable energy level.
- Muscle Loss: The body might begin to break down muscle tissue for protein, especially if protein intake is very low.
- Metabolic Changes: Also, metabolism slows down to conserve energy. You might experience dizziness, weakness, and difficulty concentrating.
Extended Phase (Days 11-21):
- Nutrient Deficiency: Prolonged fasting can lead to deficiencies in essential vitamins and minerals, affecting overall health. Symptoms might include hair loss, skin problems, and weakened immune function.
- Muscle Degradation: If you continue fasting can lead to significant muscle loss, which might affect physical strength and overall health.
- Organ Strain: The body might begin to strain vital organs, particularly the heart and kidneys, as it adapts to prolonged fasting.
Refeeding Phase:
- Refeeding Syndrome: After a prolonged fast, reintroducing food must be done carefully to avoid refeeding syndrome, a potentially dangerous condition caused by rapid shifts in electrolytes and fluids.
General Considerations:
- Mental and Emotional Effects: Extended fasting can impact mood and mental clarity. Some people report feeling euphoric initially, but others may experience irritability or depression.
- Medical Supervision: Fasting for such an extended period should be done under medical supervision to monitor health markers and ensure safety.
