Man goes viral after 13kg weight loss due to water fasting: Benefits & risks of this growing trend

Fasting has been a part of many major religions for centuries, and water fasting is a specific type where only water is consumed for a set period, typically between 24-72 hours. This method is embraced for various health reasons such as weight loss, detoxification, and spiritual enlightenment. While human studies on fasting are limited, the existing research indicates several potential benefits.

Addis Miller from Costa Rica made headlines recently with his unique approach to weight loss over 21 days – through water fasting.

In his YouTube video, Addis recounted his transformative journey, stating, “Earlier this year, I took on a 21-day water fast in Costa Rica. It was an incredibly life-changing experience, and I’m thrilled to share some of the highlights from my journey.” He detailed his fasting regimen throughout the three weeks, noting, “21-day water fast (No food, or salts). I shed 13.1kg (28lbs) and dropped 6% body fat. While this video showcases my body fat and weight loss, the fast was much more than that,” Addis also shared on Instagram.

Benefits of Water Fasting

The main advantage of water fasting is inducing nutritional ketosis, where the body shifts from burning glucose to burning fat for energy. This state may offer several health benefits:

May lower blood pressure:

A study involving 174 participants with borderline hypertension showed that medically supervised water fasting for 10-11 days normalized blood pressure in 90% of the subjects. This suggests potential benefits for those at risk of heart disease and stroke.

Potential to reverse Type 2 Diabetes:

Research involving 36 diabetic participants revealed that intermittent fasting over three months reduced the need for diabetes medications and led to remission in over half of the cases.

Improved heart health:

Fasting may protect against heart disease by reducing oxidative stress and inducing ketosis. Post-heart attack fasting has shown improvements in risk factors such as high blood pressure, cholesterol, diabetes, and obesity.

Reduced risk of disease:

Fasting stimulates autophagy, a process where cells break down old or damaged parts, potentially lowering the risk of diseases like cancer and neurodegenerative disorders.

Risks and Side Effects

Despite its benefits, water fasting isn't suitable for everyone and can pose risks, particularly for individuals with medical conditions.

Nutritional Deficiencies:

Prolonged fasting can lead to deficiencies in essential nutrients, causing weakness, dizziness, and severe health issues.

Dehydration:

While water is essential, excessive intake without electrolytes can lead to imbalances and dehydration.

Metabolic Impact:

Extended fasting can slow down metabolism, leading to potential weight gain post-fast.

Medical Considerations:

People with conditions like diabetes, cardiovascular diseases, or eating disorders should avoid water fasting or do it under strict medical supervision.

Is Water Fasting Right for You?

Water fasting might be suitable if you don’t have the conditions mentioned above and aren't on medication. However, the absence of regular food and electrolytes might cause fatigue and brain fog. Any weight loss during fasting is often water weight or muscle mass, not fat. Always ensure adequate hydration and electrolyte balance to avoid adverse effects.

When to Consult a Healthcare Provider

Before starting a water fast, it’s advisable to discuss it with a healthcare provider, especially if your job is physically demanding or you have any medical conditions. If you experience any negative effects during the fast, seek medical advice immediately.

Alternative Approaches

For those interested in fasting, intermittent fasting or medically supervised programs are safer alternatives. These methods provide health benefits without the extreme measures of prolonged water fasting.

Water fasting may offer several health benefits, but it's not without risks. If you're considering trying it, consult with a healthcare provider first and plan carefully to ensure your safety.
