Water is essential for life, making up a significant portion of our bodies and playing a crucial role in various bodily functions. But with so many types of water available, from tap to bottled to distilled, it can be challenging to determine the best choice for hydration and overall health. Recently, distilled water has gained attention for its potential weight loss benefits. This article dives into the science behind distilled water, its effects on weight loss, and whether it's a healthy choice for everyday hydration.
What is Distilled Water?
Distilled water is a type of purified water that has undergone a distillation process. This involves boiling water, collecting the steam, and then condensing it back into liquid form. This process effectively removes impurities, minerals, and contaminants, resulting in highly purified H2O.
The Distillation Process
The distillation process is fairly simple. The water is boiled until it becomes steam, and then it is cooled down to its original liquid state. During this process, contaminants such as heavy metals and inorganic minerals are left behind. Basically, they’re too heavy to turn into steam. So once the steam is cooled and turns back into water again, it’s much cleaner than it was at the start of the process.
Purity and Uses of Distilled Water
The purity of distilled water makes it ideal for various applications where contaminants can be detrimental. Common uses include:
- Medical tools and procedures: Hospitals use distilled water to clean equipment and avoid contamination and infections. Kidney dialysis machines rely on ultra-pure water to filter waste from the blood.
- Lab tests: The absence of minerals in distilled water ensures that it does not interfere with or affect the accuracy of lab experiments.
- Cosmetics: Distilled water is often used as an ingredient in moisturizers, deodorants, and shampoos due to its purity.
- Automobiles: Distilled water won’t corrode metal engine parts or interfere with batteries, making it suitable for use in vehicles.
- Infant formula: It can be mixed with infant formula if your baby has weak immunity.
- CPAP machine: Many manufacturers recommend distilled water to extend the humidifier's life.
- Neti pot: It can be used to clear your sinuses.
- Iron: It can be used in your clothes iron to prevent scale buildup.

Hydration and Metabolism
Staying hydrated is crucial for overall health and can indirectly support weight loss. Water is essential for various bodily functions, including metabolism, digestion, and waste elimination. Drinking enough water can help the body function optimally, which may contribute to weight management.
Distilled Water's Role in Hydration
Distilled water can hydrate you, as it is primarily composed of pure H2O without any dissolved minerals or contaminants. When you drink distilled water, it enters your body and helps maintain hydration levels, just like any other form of water. It is absorbed by your cells, replenishing fluids lost throughout the day and supporting essential bodily functions.
Potential Mechanisms for Weight Loss
- Reduced Calorie Intake: Drinking water before meals can help reduce calorie intake by creating a feeling of fullness. One small study found that drinking water before meals helped naturally reduce calorie intake, which may in turn support healthy weight management.
- Increased Metabolism: Some studies suggest that increasing water intake can help speed up metabolism by promoting lipolysis, the breakdown of fats.
- Detoxification: Distilled water's purity may help flush out toxins from the body, supporting natural detoxification processes.
The "Water In, Fat Out" Concept
The concept of "water in, fat out" suggests that drinking water can help the body eliminate fat and toxins. When the body is in "fat-burning mode," it breaks down fat lipids in fat cells and releases their energy. Water helps transport and eliminate the byproducts of this process, such as hydrogen, carbon, and oxygen.
Steve Zim's Perspective
Steve Zim, a celebrity trainer and author of "Super Hero Nutrition," emphasizes the importance of water in weight loss. He suggests consuming at least two liters of water a day, noting that many times people feel hungry when they're actually thirsty. Zim also recommends avoiding sugary drinks and fruit juices, as they can spike blood sugar levels and hinder fat loss.

Controversies and Misconceptions About Distilled Water
Despite its potential benefits, distilled water has faced several controversies and misconceptions.
Mineral Leaching
One common myth is that distilled water leaches minerals from the body due to its lack of minerals. However, our bodies primarily obtain minerals from food, not water. As long as a balanced diet is maintained, drinking distilled water should not pose a risk for mineral depletion.
Taste and Hydration
Some people find distilled water to be "flat" or "tasteless," leading to the misconception that it is less hydrating than other water sources. However, the absence of minerals does not affect its ability to hydrate.
Electrolyte Balance
There's a belief that drinking distilled water alone could lead to an imbalance in electrolytes and dehydration due to its lack of sodium, potassium, and magnesium. While distilled water doesn’t contain electrolytes, this is not an issue for short-term hydration, especially when coupled with a balanced diet and electrolyte supplementation.
Long-Term Consumption and Mineral Deficiency
Concerns exist that long-term consumption of distilled water could lead to mineral deficiencies, particularly for those who rely on it as their main water source. Drinking only distilled water over long periods could, in theory, contribute to mineral imbalances if the individual’s diet is inadequate in providing essential minerals. However, this risk is low for most people who maintain a well-balanced diet.
Distilled Water as a "Magic Solution" for Weight Loss
Some believe that distilled water is a "magic solution" for weight loss due to its purity. While distilled water can support weight loss by keeping the body hydrated and preventing water retention, it's not a miracle drink. Weight loss still depends on a healthy diet and exercise routine.
Practical Tips for Incorporating Distilled Water into a Fitness Routine
If you choose to incorporate distilled water into your fitness routine, here are some practical tips:
- Use for Mixing Supplements: Distilled water provides a neutral base for making sports drinks, protein shakes, and recovery drinks, ensuring consistency without altering the taste or affecting the effectiveness of your supplements.
- Rehydrate After Workouts: Distilled water is quickly absorbed into the body, making it ideal for rehydration post-workout. Pair it with an electrolyte supplement for balanced hydration.
- DIY Hydrating Drinks: Create your own healthy, low-calorie drinks using distilled water as a base. Add herbal teas or natural flavorings to stay hydrated without added sugars.
- Support Detoxification: Distilled water helps flush out toxins due to its purity. Use it to aid your body’s natural detox processes alongside a clean diet.
Potential Downsides of Distilled Water
While distilled water offers several benefits, there are potential downsides to consider:
- Lack of Essential Minerals: Distilled water lacks essential minerals like calcium and magnesium, which are naturally found in other water sources.
- Acidity: The distillation process can make water more absorbent, causing it to absorb carbon dioxide from the air and become a carbonic acid solution. Drinking this solution can increase the acidity of your body.
How Much Water Should You Drink Daily?
While there's no specific amount of water recommended for weight loss, general guidelines suggest:
- Men: 15.5 cups (3.7 liters or 124 ounces) per day
- Women: 11.5 cups (2.7 liters or 92 ounces) per day
This includes water and fluids from food.
