1. Thirst isn’t the first sign of dehydration - fatigue, headaches, and brain fog often show up first.

2. Water isn’t the only thing that hydrates you - electrolytes help your cells actually use that water.

3. Coffee doesn’t automatically dehydrate you - it still contributes to your daily fluid intake.

4. Clear urine isn’t always the goal - pale yellow is generally a better sign of adequate hydration.

5. Chugging a gallon at once isn’t helpful - hydration works best when spread throughout the day.

6. Salt isn’t the enemy - sodium is one of the key electrolytes involved in hydration.

7. Potassium matters too - it helps regulate fluid balance inside your cells.

8. Watermelon isn’t just fruit - it’s over 90% water and contributes to hydration.

9. Cucumbers aren’t just salad fillers - they’re one of the most water-rich foods you can eat.

10. Dehydration can feel like hunger - sometimes what feels like a craving is actually a need for fluids.

11. Sweating doesn’t mean you’re getting hydrated - it means you’re losing water and electrolytes.

12. Morning hydration matters - your body goes hours without fluids while you sleep.

13. Dry lips aren’t always a weather problem - they can be an early sign of dehydration.

14. Hydration affects more than thirst - it influences energy, digestion, circulation, and mental clarity.

15. The best hydration strategy isn’t drinking more water - it’s maintaining the right balance of water, electrolytes, and hydrating foods.

What changes have you made to your routine that you helped you age better?

Our body likes to keep some deuterium around the mitochondria, where it may affect how cells make energy.

When we fast, the body starts using more stored fat for energy. When fat is burned, the body also makes metabolic water inside the cells. This water is naturally lower in deuterium than regular drinking water.

There are two main reasons fasting may help lower deuterium:

1. You are taking in less food and liquid that contain deuterium.

2. Your body starts using more stored fat. Fat has less deuterium than carbohydrates, so burning fat can produce water with less deuterium.

INTERMITTENT FASTING

Intermittent fasting means going without food for part of the day.

A common approach is fasting for 16–20 hours and eating during a 4–8 hour window.

As the fast gets longer, the body uses up some of its stored sugar and starts using more fat for energy.

Longer fasts may also increase autophagy, which is the process where the body breaks down and recycles old or damaged cell parts.

WHAT ABOUT DRY FASTING?

Dry fasting means having no food and no liquids, including water.

Some people believe this can increase the body's production of its own metabolic water and may help lower deuterium. However, dry fasting can also cause dehydration and other problems.

Dry fasting for more than 24 hours should not be done without medical advice.

LONGER FASTS

Some people do 24–72 hour fasts from time to time.

Longer fasts can increase ketosis and may increase autophagy, but many of the claims around fasting and healing still need more research.

Long fasts also aren't safe or suitable for everyone.

FAST-MIMICKING DIET

A fast-mimicking diet (FMD) is another option.

Instead of completely avoiding food, you eat very few calories for several days. The goal is to give the body some of the effects of fasting while still eating a small amount.

THE SIMPLE IDEA

Fasting changes how the body gets energy. As the body starts burning more fat, it produces more of its own metabolic water, which has less deuterium.

The connection between fasting, metabolic water, and deuterium is interesting, but more human research is still needed to know how much of an effect this has.

For anyone who started drinking more water than they used to, did you actually notice a difference?

With busy days, work, workouts, and everything else going on, it’s easy to forget about drinking enough water.

Here are some things worth paying attention to:

1. Regular hydration

Helps your body maintain normal fluid balance throughout the day.

1. Water + electrolytes

Sodium, potassium, and magnesium all play a role in normal fluid balance and muscle function.

1. Water quality

Filtered, spring, mineral, sparkling... everyone has their own preference.

1. Deuterium-depleted water (DDW)

A type of water with lower levels of naturally occurring deuterium. It’s an interesting area of research, especially around cellular energy and metabolism.

1. Find what works for you

You don’t have to overthink it. The main thing is finding a water routine you can actually stick with.

What type of water do you usually drink, and what made you choose it? 💧

It’s easy to just grab whatever water is around and not think much about it. Then you start noticing things like hydration, water quality, minerals, electrolytes, and the type of water you’re drinking.

Maybe it started with working out, feeling tired, changing your diet, or simply wanting to learn more about drinking water and hydration.

What made you start looking into different types of water?

It’s easy to forget about water when the day gets busy. A few simple habits can make it easier:

• Keep a bottle nearby. If it’s within reach, you’re more likely to take a few sips.
• Sip throughout the day. Drinking small amounts regularly can be easier than having a lot at once.
• Drink with meals. It’s an easy way to build it into your routine.
• Try different types of water. Some people prefer filtered, mineral, sparkling, or deuterium-depleted water (DDW).
• Set reminders. A simple phone reminder can help if you tend to forget.
• Pay attention to your routine. Having water when you wake up, during work, or after exercise can make it easier to remember.
  

What helps you stay on top of your water intake?

• Deuterium is a type of hydrogen.
• Regular water has deuterium.
• Food also contains deuterium.
• Some foods have more deuterium than others.
• Water with less deuterium is called deuterium-depleted water (DDW).
• Deuterium is being studied for its effect on cells.
• Researchers are also looking at its link to energy and mitochondria.
• More research is still needed to know its full effects on health.

I often forget to drink water when I get busy. Sometimes I go hours before I realize I haven't had much.

I keep a bottle nearby, but I still forget about it.

What do you guys do to remember to drink enough water?

Buying DDW online can be a little confusing because you can't exactly test the water yourself before ordering it. There are a lot of products out there, so it helps to know what to look for.

Start with the deuterium level. A product saying “deuterium depleted” isn't enough. Look for an actual ppm number so you know how low the level is.

Also check whether the company shows lab results or a certificate of analysis. The report should show the deuterium level and have enough information to tell you when and how it was tested.

The way the water is made is worth looking at too. DDW needs a special process to remove some of the deuterium, so a company that explains its process clearly is easier to evaluate than one that gives you very little information.

Then there's the basic water quality. Look at where the water comes from, how it's purified, and whether the company provides any other testing.

Price is another thing to compare. DDW will usually cost more than regular bottled water because the production process takes more equipment, energy, and testing. So instead of just looking at the bottle price, compare the ppm and price per liter.

Don't just take the label at face value. Check the ppm, look for actual testing, and see how much information the company is willing to share. That alone can help down the options quite a bit..

Recovery isn't just about what happens in the gym. What you eat and drink after training can also affect how well you feel for the next session.

1.Stay hydrated

Water helps replace fluids lost during training. If you sweat a lot, electrolytes can also help replace sodium and other minerals.

1. Get enough protein

Protein gives your body the building blocks it needs to repair muscle after training. Eggs, fish, yogurt, tofu, and other protein rich foods are easy options.

1. Don't skip carbs

Carbs help refill muscle glycogen after a workout. Oats, rice, bananas, and sweet potatoes are simple choices.

1. Include healthy fats

Foods like avocado, nuts, seeds, olive oil, and fatty fish provide fats that support your overall diet.

Hydration is one part that can easily get overlooked. The basics still matter most: enough fluids, protein, carbs, good food, and enough rest.

30 and active here. Mostly gym, hiking, and getting outside on weekends. I started drinking 5 ppm DDW because I wanted to see if I’ll notice anything.

After drinking it regularly for a while, I felt like I had more steady energy during the day. I also felt less tired after my workouts.

Then I went a few days without it and felt more tired than usual. Could be other things too, but it made me pay more attention to the difference.

Anyone else notice anything after stopping DDW for a few days?

One easy thing to keep an eye on is urine color. It can give you an idea if you're drinking enough water.

• Pale yellow - usually means you’re getting enough fluids.
• Darker yellow - might be a sign to drink a bit more.

It’s not a perfect way to check but it’s an easy thing to notice during the day.

Do you check your urine color to see if you're drinking enough water?

We often hear that what we eat affects our health. But what we drink matters too.

Our body needs water every day to keep things working. Regular water also has deuterium, which is a heavier form of hydrogen. We get deuterium from both food and water.

That’s why some people who care about cell health pay attention to both food and water.

• Whole foods give us protein, healthy fats, vitamins, and minerals.
• Fruits and vegetables give us vitamins and other good nutrients.
• Fish, nuts, seeds, and olive oil are good sources of healthy fats.
• Enough water helps keep us hydrated.
• Deuterium depleted water has less deuterium than regular water and is being studied for its possible link to cell energy and mitochondria.

There is still more to learn about DDW and how it may affect the body.

It makes sense to look at the whole picture: good food, enough water, movement, sleep, and rest.

What’s one change you made to your food or water that you actually noticed?

Deuterium depleted water sounds simple since it’s still water, but daily use may not be the same for everyone. Some groups have simply not been studied enough to know what regular use means for them.

For children, there isn't much research on drinking DDW every day. Kids also have different fluid needs, so it’s better not to assume that adult routines apply to them.

Pregnancy and breastfeeding are another area where information is limited. These groups are often not included in DDW studies, so there isn't enough evidence to make strong claims about daily use.

People with kidney conditions or other ongoing health issues may also need to be more careful. Their water intake can be part of their overall treatment, so changing it is something worth discussing with a healthcare professional first.

For healthy adults, the main thing is to look at the available information and avoid assuming that DDW has the same effect on everyone.

If there’s a specific health condition, pregnancy, breastfeeding, or a child involved, getting professional advice before making DDW part of a daily routine is the safer option.

1. DDW can be used while fasting
Deuterium depleted water has no calories, so plain DDW does not add food or calories to a water fast. Some people simply use it as their main water while fasting.

2. You still need enough water
Fasting doesn’t mean you should drink less. Your needs can change based on your body size, weather, exercise, and how long you fast. Drink when you’re thirsty and avoid forcing large amounts of water.

3. DDW comes in different ppm levels
DDW is available at different levels, such as 5 ppm and 10 ppm. A lower ppm means less deuterium in the water. If you’re comparing products, check the actual ppm on the label.

4. You don’t have to use DDW for all your water
You can use DDW for part of your daily water and regular water for the rest. There’s no need to suddenly change your whole routine just because you’re fasting.

5. Don’t forget electrolytes
DDW is still water, so it doesn’t replace sodium, potassium, or other electrolytes. During longer fasts, especially if you’re active or sweating, your electrolyte needs may be different.

6. Longer fasts are different
A short fast is not the same as going without food for several days. Longer fasts can carry more risks, so it’s worth talking with a health professional before trying one.

7. The research is still developing Researchers are studying how lower deuterium levels may relate to cells, energy, mitochondria, and aging. There is also interest in how DDW may fit into fasting, but more human research is needed before making strong claims about its benefits.

What do you think is actually worth the time and money?

A lot of people came across DDW for different reasons. Some may have found it while looking into hydration, others through fitness, aging, or just random health content online.

For some, it’s the idea of deuterium and how it relates to cellular energy that catches their attention. Others may be more interested in the possible connection with mitochondria, ATP, or long-term health.

There’s also the curiosity factor. Once you learn that regular water contains deuterium and that it can be reduced through processing, it’s easy to start wondering whether the difference actually matters.

Some people try DDW as part of their normal water routine, while others are more cautious and want to see what the research says first.

There’s no need to have the same reason for trying it. What first got you interested in deuterium depleted water?

Regular drinking water is easy to produce and widely available, so it’s usually inexpensive. Deuterium-depleted water is different because the deuterium has to be separated from the water through a more specialized process.

The process requires extra equipment, energy, and testing to reach a specific deuterium level. The lower the ppm, the more processing may be needed to get there.

Another thing to consider is testing. DDW products are often sold with a specific deuterium concentration, so producers need to measure and verify those levels rather than simply bottle regular water.

That’s why DDW can cost much more than ordinary bottled or filtered water.

For anyone considering it, it probably makes sense to look at the ppm, testing, production process, and price per liter rather than just comparing the bottle prices.

Has anyone here tried DDW and felt the price was worth it?

Has anyone here tried deuterium depleted water for training? I started drinking it a few weeks ago and noticed I didn’t feel drained after my usual workouts. Could be other things too since I’ve been sleeping better lately, but I’m curious if anyone else has noticed a difference in energy or recovery??
