What Drinks Help You Lose Weight? Drinks That May Actually Help

The drinks that help you lose weight are mostly the boring ones: water, unsweetened coffee, plain tea, and low-calorie homemade drinks that replace sugary options.

No single weight loss drink melts fat, but the right swaps can make a real difference. In a 2015 trial, adults who drank 500 ml of water 30 minutes before main meals lost 1.3 kg more over 12 weeks than a comparison group.

A large Harvard-led analysis of over 100,000 people found that each extra daily cup of unsweetened coffee was linked to about 0.12 kg less weight gain over four years, while adding one teaspoon of sugar wiped out that benefit.

Meanwhile, a popular 2024 apple cider vinegar weight loss study was retracted in September 2025 after its results were judged unreliable.

Here’s what actually works, what doesn’t, and simple homemade weight loss drinks you can make today.

Can A Drink Really Help You Lose Weight?

A drink can help you lose weight, but usually not in the way social media suggests. The biggest benefit comes from what a drink replaces, not from any fat-burning magic.

Think about it this way. A large sweetened coffee, a bottle of soda, or a glass of packaged juice can each add hundreds of calories to your day.

Swap them for water or plain tea, and you’ve cut those calories without eating less food.

Some drinks can also help indirectly by:

• Making you feel fuller before meals
• Curbing cravings between meals
• Giving you a small, short-lived bump in energy use (caffeine)
• Replacing late-night snacking with a warm, low-calorie ritual

What no drink can do is “cut fat” from your belly while you sit still. Weight loss still comes down to taking in fewer calories than your body uses over time.

What Are The Best Drinks That Help You Lose Weight?

Here’s a quick comparison of the most popular drinks for weight loss, ranked by how well the evidence supports them.

Drink	How It Might Help	Strength Of Evidence	Calories (Plain)
Water	Replaces caloric drinks, may reduce meal size	Good	0
Unsweetened black coffee	Linked to slightly less weight gain, may curb appetite	Moderate (observational)	Near 0
Plain green tea	Small possible effect on metabolism	Weak to modest	Near 0
Plain black or herbal tea	Calorie-free swap for sugary drinks	Indirect	Near 0
Low-fat milk or buttermilk	Protein may help fullness	Indirect	Moderate
Homemade lemon, ginger, or spice water	Low-calorie, flavorful swap	Indirect	Near 0
Apple cider vinegar drinks	Popular, but key study retracted	Weak	Near 0
Diet sodas	Fewer calories short term	WHO advises against for weight control	Near 0
“Detox” or “fat cutter” teas	Mostly marketing	Little to none	Varies

Let’s look at each one more closely.

Is Water The Best Weight Loss Drink?

Yes. Water is the best weight loss drink for almost everyone, because it has zero calories, costs next to nothing, and has actual trial evidence behind it.

In a randomized trial in Birmingham, England, 84 adults with obesity were split into two groups.

One group drank 500 ml of water 30 minutes before their main meals, while the other was asked to imagine feeling full.

After 12 weeks, the water group lost 1.3 kg more. The researchers described this as preliminary evidence of moderate weight loss.

How to use water for weight loss:

• Drink a large glass (about 500 ml) 30 minutes before lunch and dinner
• Keep a bottle on your desk as a visual reminder
• Drink water when you feel snacky, since thirst is easy to mistake for hunger
• Replace at least one sugary drink a day with water

Does Coffee Help You Lose Weight?

Plain coffee may help a little, as long as you skip the sugar.

A study published in the American Journal of Clinical Nutrition in 2023 tracked more than 100,000 adults across three long-running U.S. health studies.

Each additional daily cup of unsweetened coffee, caffeinated or decaf, was associated with about 0.12 kg less weight gain over four years.

But adding a teaspoon of sugar per day was linked to about 0.09 kg more weight gain, cancelling out much of the benefit.

Two important points:

1. The effect is small. Researchers noted it works out to roughly 30 grams of avoided weight gain per year.
2. It shows a link, not proof. This was an observational study, so it can’t prove coffee caused the difference.

Interestingly, adding cream or milk wasn’t linked to extra weight gain in that study, but sugar clearly was. So if you love coffee, keep it plain or with a splash of milk, and skip the syrups.

Is Green Tea A Fat Burning Drink?

Green tea is often called a fat burning drink, but the evidence is much weaker than the hype.

The NIH Office of Dietary Supplements has reported that some studies show modest weight loss with green tea supplements, but the effect is small and unlikely to be clinically meaningful.

Plain brewed green tea is still a great choice because it’s calorie-free and pleasant to sip. Just don’t expect it to burn belly fat on its own.

One safety note: concentrated green tea extract supplements have been linked to rare cases of liver damage. Brewed green tea is a different story and is generally considered safe for most people.

Does Apple Cider Vinegar Help With Weight Loss?

Apple cider vinegar drinks became hugely popular after a 2024 study suggested daily vinegar helped young people with overweight lose 6 to 8 kg in 12 weeks.

That study has since been retracted. In September 2025, the BMJ Group retracted it after statistical experts reviewed the data.

The publisher said the results were unreliable and asked journalists to stop citing it. The trial also hadn’t been registered before it began, which broke the journal’s own rules.

Retraction Watch also noted that other research doesn’t support the claim that apple cider vinegar raises metabolic rate.

Bottom line: there’s no strong evidence that apple cider vinegar causes weight loss. If you enjoy it diluted in water, it’s fine in small amounts, but it’s acidic and can irritate your teeth and stomach. Never drink it undiluted.

Are Diet Sodas Good For Weight Loss?

Diet sodas cut sugar and calories, but they’re not the weight loss shortcut many people hope for.

In May 2023, the World Health Organization released a guideline recommending against using non-sugar sweeteners for weight control. WHO’s review found no long-term benefit in reducing body fat in adults or children.

WHO labeled this a “conditional” recommendation based on low-certainty evidence, and it doesn’t apply to people with diabetes.

Still, the message is clear: plain water or unsweetened drinks are better long-term choices than artificially sweetened ones.

Practical tip: if you’re hooked on regular soda, switching to diet soda can be a stepping stone. Aim to move toward sparkling water or plain water over time.

What Is The Best Morning Drink For Weight Loss?

The best morning drink for weight loss is one that’s low in calories, hydrating, and easy to stick with. Good options include:

• A big glass of water right after waking up
• Black coffee or coffee with a splash of milk (no sugar)
• Plain green or black tea
• Warm lemon water for flavor
• Ginger tea if you prefer something warming

There’s nothing magical about drinking these on an empty stomach. The benefit is starting your day without a sugary drink and staying hydrated.

What to avoid in the morning:

• Sweetened coffee drinks and flavored lattes
• Packaged fruit juices, even “100% juice” in large glasses
• Sugary energy drinks
• Milkshakes or smoothies loaded with honey, sugar, or ice cream

Is There A Metabolism Booster Drink That Actually Works?

Caffeine can give your metabolism a small, temporary nudge, which is why coffee and tea often show up on lists of drinks to boost metabolism.

But the effect is modest and shouldn’t be your weight loss strategy.

Many so-called metabolism increase drinks rely on caffeine, chilli, cinnamon, or ginger. None of these has been shown to create meaningful long-term weight loss on its own.

Caffeine safety: the FDA says up to 400 mg of caffeine a day, roughly four to five cups of coffee, isn’t generally associated with dangerous effects in healthy adults.

Too much can cause jitters, anxiety, a fast heartbeat, and poor sleep. Poor sleep, in turn, can make weight loss harder.

Drink	Approximate Caffeine (FDA Figures)
Coffee (8 oz / 240 ml)	80 to 100 mg
Green or black tea (8 oz / 240 ml)	30 to 50 mg
Cola (12 oz / 355 ml)	30 to 40 mg
Energy drink (8 oz / 240 ml)	40 to 250 mg

Watch out for “metabolism booster” supplements and powders. Many contain high doses of caffeine plus other stimulants, and their weight loss claims usually go far beyond the evidence.

If you’re considering a powdered tonic like Nagano Tonic, check the ingredient amounts and the evidence before you buy.

What Should You Drink To Lose Belly Fat?

There’s no drink that targets belly fat specifically. You can’t choose where your body burns fat from.

When you lose weight overall, belly fat shrinks along with fat from other areas, in a pattern largely set by your genes and hormones.

That said, these drinks support overall fat loss, which includes your belly:

• Water instead of sugary drinks
• Unsweetened coffee or tea
• Low-calorie homemade drinks like lemon, mint, or cucumber water
• Buttermilk (chaas) without added sugar, which is light and filling

And these drinks can work against you:

• Sugary sodas and packaged juices
• Alcohol, especially beer and sweet cocktails
• Sweetened coffee and tea
• Large smoothies with added sugar

Can You Lose Belly Fat In 1 Week With A Drink?

No. If you search “what to drink to lose belly fat in 1 week,” you’ll find lots of bold promises, but real fat loss doesn’t happen that fast.

What you can change in a week is bloating. Drinking more water, cutting salty processed foods, reducing fizzy drinks, and avoiding foods that upset your stomach can make your belly look and feel flatter within days.

That’s mostly less water retention and gas, not fat loss. For actual fat loss, think in months. Steady weight loss is generally around 0.5 to 1 kg per week.

Is There An Instant Or Fast Weight Loss Drink?

There’s no safe instant weight loss drink. Products sold as a fast weight loss drink or instant weight loss drink usually work in one of three ways:

1. They’re diuretics. They make you urinate more, so you lose water weight that comes right back.
2. They’re laxatives. Some “detox” or “slimming” teas contain herbal laxatives. You lose water and stool, not fat, and frequent use can upset your digestion.
3. They’re just marketing. Some are simply flavored drinks with big promises.

If a drink promises dramatic weight loss in days, be skeptical. The FTC has long warned consumers that there are no miracle weight-loss products.

Do “Fat Cutter” Drinks Really Work?

“Fat cutter drink” is a popular phrase, especially in recipe videos, but no drink literally cuts fat.

Most fat cutter drink recipes combine ingredients like lemon, ginger, cumin, cinnamon, or vinegar with warm water.

These drinks can still be useful because they:

• Have almost no calories
• Replace tea with sugar or other sweet drinks
• Help you stay hydrated
• Give you a pleasant routine that supports healthier habits

Just enjoy them for what they are: tasty, low-calorie swaps. The fat loss comes from your overall eating habits, not the drink itself.

How Do You Make A Weight Loss Drink At Home?

Homemade weight loss drinks are cheap, easy, and free of the added sugar found in many store-bought options.

Here are simple recipes you can try. None of these burn fat directly, but all of them are low-calorie alternatives to sugary drinks.

Lemon Ginger Water

• 1 glass warm water
• Juice of half a lemon
• A few thin slices of fresh ginger

Steep the ginger for 5 minutes, then add lemon. Skip the honey, or use just a little if needed.

Jeera (Cumin) Water

• 1 teaspoon cumin seeds
• 1 glass water

Soak the seeds overnight, boil for a few minutes in the morning, strain, and sip warm.

Cinnamon Tea

• 1 small cinnamon stick
• 1 cup water

Boil for 5 to 10 minutes and strain. It has a naturally sweet taste, so you won’t miss the sugar.

Mint And Cucumber Water

• A handful of fresh mint leaves
• A few cucumber slices
• 1 litre cold water

Leave it in the fridge for a couple of hours. This is a refreshing summer drink and a great soda replacement.

Spiced Buttermilk (Chaas)

• 1 part plain curd
• 3 parts water
• Pinch of roasted cumin powder, salt, and chopped coriander

Blend and serve chilled. It’s light, filling, and provides some protein.

Homemade Drink	Best Time	Why It Helps
Lemon ginger water	Morning	Hydrating, flavorful, nearly calorie-free
Jeera water	Morning	Warm, satisfying swap for sweet tea
Cinnamon tea	Evening	Naturally sweet taste without sugar
Mint cucumber water	Daytime	Refreshing soda replacement
Spiced buttermilk	After lunch	Light, filling, with some protein

What Is The Best Weight Loss Drink For Females?

The best weight loss drink for females is the same as for anyone else: water, unsweetened tea or coffee, and low-calorie homemade drinks.

Women don’t need special “female” weight loss drinks, despite what marketing suggests.

A few points are worth highlighting, though:

• Pregnancy: experts generally advise limiting caffeine to 200 mg per day during pregnancy. Avoid herbal “slimming” teas and supplements unless your doctor approves them.
• Breastfeeding: keep caffeine moderate and check with your doctor before trying weight loss products.
• Iron levels: tea and coffee can reduce iron absorption when taken with meals. If you have low iron, try drinking them between meals instead.
• PCOS or thyroid conditions: these can affect weight. Talk to your doctor about a plan that suits you, rather than relying on drinks.

Which Drinks Should You Avoid When Trying To Lose Weight?

Cutting these drinks can make a bigger difference than adding any “weight loss drink”:

Drink To Limit	Why	Better Swap
Regular soda	High in sugar, no fullness	Sparkling water with lemon
Packaged fruit juice	Concentrated sugar, little fiber	Whole fruit plus water
Sweetened coffee drinks	Sugar and syrups add up fast	Black coffee or coffee with milk
Sweetened tea	Easy to add several teaspoons of sugar	Unsweetened or lightly spiced tea
Energy drinks	Sugar plus high caffeine	Plain tea or water
Alcohol	Calories plus lower willpower around food	Soda water with lime
Milkshakes and dessert smoothies	Very high in calories	Plain buttermilk or a small fruit smoothie
“Detox” or slimming teas	Often laxatives, no fat loss	Plain herbal tea

Remember the coffee study: even a single teaspoon of daily sugar was linked to extra weight gain over time. Small amounts add up across weeks and months.

How Do Weight Loss Drinks Fit Into A Complete Plan?

Drinks work best as one piece of a bigger plan. To lose weight steadily, combine smart drink choices with:

• A modest calorie deficit from smaller portions and fewer processed foods
• Protein at every meal to help you stay full
• Plenty of vegetables and fiber
• Enough sleep, since poor sleep increases cravings
• Daily movement, even if it’s just walking

If working out isn’t realistic right now, our article on how to lose weight without exercise shows how to build a calorie deficit through food and sleep alone.

Here’s a sample day of drinks that supports weight loss:

Time	Drink
Wake up	Large glass of water or lemon ginger water
Breakfast	Black coffee or tea with a splash of milk, no sugar
Mid-morning	Water
30 minutes before lunch	500 ml water
After lunch	Spiced buttermilk
Afternoon	Green tea or mint cucumber water
30 minutes before dinner	500 ml water
Evening	Cinnamon tea or caffeine-free herbal tea

Who Should Be Careful With Weight Loss Drinks?

Most simple drinks like water, plain tea, and lemon water are safe for nearly everyone. Be more cautious if you:

• Have acid reflux or ulcers: lemon, vinegar, and coffee may worsen symptoms
• Have heart rhythm problems or high blood pressure: watch caffeine intake
• Are pregnant or breastfeeding: limit caffeine and avoid slimming teas
• Take medications: some herbal drinks and supplements can interact with medicines
• Have kidney problems: check with your doctor before drastically increasing fluids
• Have a history of eating disorders: avoid laxative teas and restrictive “drink only” plans

If you’re unsure, ask your doctor or a registered dietitian.

What Is The Bottom Line On Drinks That Help You Lose Weight?

The best drinks that help you lose weight are simple: water, unsweetened coffee, plain tea, and homemade low-calorie drinks.

Their real power lies in replacing sugary sodas, juices, sweet coffees, and alcohol, which can quietly add hundreds of calories a day.

Skip “instant” weight loss drinks, laxative teas, and fat cutter promises, and be wary of trends built on weak or retracted research.

Pair smart drink choices with balanced meals, good sleep, and daily movement such as a simple 3-minute interval walking routine, and you’ll see steady, lasting results.
