Drink Water & Lose Weight Faster: Powerful Benefits You Need to Know

Let’s be real — you probably rolled your eyes when you first heard someone say that drinking water can help you lose weight. It sounds gimmicky, doesn’t it? Like one of those wellness blogs trying to turn something pointless into a full-blown diet strategy. BUT…the research is there, and it’s actually pretty wild. I’m not saying downing water suddenly burns crazy amounts of fat or magically stops you from eating. But water does affect your appetite, metabolism, and even the way your body stores fat in several surprising ways. If you’re starting a weight loss journey or have hit a plateau and need some new tips, keep reading about hydration’s impact on weight loss. We’ll talk about how water can control appetite, the best times to drink it, and how even athletes use water to blast fat.

Along with staying hydrated, choosing the right sweeteners matters—check out our post Is Honey Good for Weight Loss? to learn more.

How Drinking Water Helps With Weight Loss

Ever eaten a big meal and still felt… kind of hungry? Or found yourself snacking all day despite technically eating enough calories? Here’s a little secret: sometimes (or quite often, really) that hunger isn’t actually hunger at all. It’s thirst. Your brain has a weird tendency to interpret thirst as hunger when you’re mildly dehydrated. Instead of drinking water, we eat. And over time, those unnecessary calories add up. Thirst disguising itself as hunger isn’t the only way water impacts appetite, though. Drinking water before and during meals can actually help you eat less. How? Because water fills you up. Like, physically fills your stomach with something that isn’t food. When you drink a whole glass of water before eating, your stomach stretches slightly and tells your brain that it’s starting to get full. When you drink while eating, you pause to get water and trick your brain into thinking you’re eating less. Researchers at the University of Birmingham found that adults who drank approximately 500 mL of water before each main meal lost substantially more weight over 12 weeks than those who didn’t. Here’s the takeaway:

• Drinking water before meals can help you consume less food.
• Staying hydrated throughout the day can help you avoid mistaking thirst for hunger.
• Drinking water with your meals forces you to take breaks and slows your eating pace.
• Cutting out liquid calories and replacing them with water reduces your daily intake.

Water can be a great way to naturally control appetite without weird appetite suppressants or stimulants getting in the way. Your body is naturally programmed to feel full after eating a certain amount. Water simply allows that process to work without interference from extra calories.

Benefits of Drinking Water to Lose Weight

Aside from controlling your appetite, drinking water can also benefit your body fat loss in other ways.

It boosts your metabolism and calorie burning.

Here’s how water can directly cause you to burn more calories, even at rest: Drinking cold water boosts metabolism! Your body has to work to heat that water up to your normal temp, which takes calories. It’s a small number, but it’s legit. One study showed that drinking around 500ml of water increased metabolic rate by up to 30% for about half an hour.

It helps you burn fat.

If you’ve been dehydrated for longer periods of time, your kidneys aren’t able to do their job properly. So your liver jumps in to help. Sounds like a problem? It is. Your liver is responsible for breaking down fat stores into energy. When it’s working double-time, helping your kidneys, there’s less capacity to burn fat. So instead of storing fat, drink water!

Tips For Drinking Water

Soda contains around 140 calories and 39 grams of sugar per 12-ounce can.

Let that sink in for a second. How many people do you know who drink 2, 3, or 4 sodas a day? That’s 400–560 calories of sugar water your body hardly recognizes as filling. And your hunger won’t go down very much either.

But there’s good news. By replacing just ONE sugary beverage with a calorie-free alternative (you guessed it!), you could cut hundreds of calories per day. Here’s an example:

Drink Calories (approx.) Sugar (approx.)

Regular soda (12oz) 140 calories 39g
Sweetened icea (8 oz) (16oz) 180 calories 45g
Orange juice (8oz) 110 calories 21g
Energy drink (16 oz): 220 calories, 54 g. Water: 0 calories, 0 g.

*NOTE—we aren’t saying NEVER drink these things. Obviously, fruit juices and the like can be much healthier than soda. But if you’re drinking multiple a day consistently, water is almost always the better option.

How Much Water Should You Drink?

We recommend taking a look at your current diet and drinking habits. If you drink soda, sweetened tea, coffee, or juice with every meal and frequently get snacks that are sugary, drink more water! Your calorie intake will decrease dramatically by cutting liquid calories, and your body will thank you. If you’re already doing a good job with liquid calories, start using water as a way to fill up before meals. Most experts recommend drinking at least half your body weight (lbs) in ounces of water daily.

Make sure to drink water before meals, in the morning when you wake up, and during workouts! If you exercise, staying hydrated is essential for good performance and body composition.

Conclusion

Sure, drinking water alone won’t magically cause weight loss. But it is one of the easiest habits to integrate into your daily routine that can help you reach your goals. Not only can staying hydrated help with appetite control and suppress calories, but it can also slightly increase metabolism and help with the body’s ability to burn fat. Water can enhance your weight loss efforts in several ways:

It’s convenient. There’s no fancy powder to mix with water. Drink water instead of high-calorie drinks, and you’ll automatically reduce your calorie intake. Plus, drinking water at strategic times can help with appetite control.

It supports your body. Hydration is essential for your body to function properly and for you to perform at your best. When trying to lose weight, you want to ensure your body has what it needs to keep going and not feel deprived. Leading an unhealthy lifestyle can cause you to crash and burn. Focus on filling your body with what it needs: enough water, a balanced diet, and plenty of movement.

Frequently Asked Questions

Can drinking cold water help you lose weight?

Yes, cold water slightly increases calorie expenditure because your body has to warm it up before use. Plus, cold water tends to taste better to some people.

Can you drink too much water?

Yes. Although it’s relatively rare, you can have TOO much water. The condition is called hyponatremia, and it occurs when your blood’s sodium levels become too diluted by water. You’d have to drink an extreme amount in a short period of time for this to happen, though. Focus on spreading your water intake throughout the day.

What if I hate drinking water?

Add flavor to it! Natural flavors like lemon, fresh mint, cucumber, berries, or ginger can add zest to your water without adding too many calories. Another option is buying a waterproof water bottle that infuses flavors as you drink.

When should you drink water to reduce appetite?

Ideally, 20–30 minutes before a meal. This gives your stomach enough time to begin to fill with water and signals FULLNESS to your brain. You can still drink water WITH your meals, just not RIGHT before you take the first bite.

Does coffee or tea count as water intake?

Yes and no. Both beverages contain caffeine, a diuretic that increases urine production. However, studies have shown that the quality of hydration from coffee and tea outweighs the diuretic effect if you drink moderate amounts. Obviously, water is still better and should make up the majority of your intake.
