Best Drinks for Weight Loss: 6 Practical Choices

Water, unsweetened tea and black coffee are the best drinks for weight loss because they can replace higher-calorie beverages without adding much energy to your day.

No drink causes weight loss on its own. The useful change is replacing a higher-calorie drink, rather than adding another drink to what you already consume. For more options organized around your needs, explore natural remedies by health goal.

6 best drinks for weight loss

The six practical choices are water, unsweetened tea, black coffee, unsweetened sparkling water, infused water and plain low-fat milk. This is a practical ranking, not a proven order of effectiveness: direct weight-loss evidence varies, and the best choice is one you can use consistently in place of a higher-calorie drink.

1. Water

How it may help: Plain water has no calories. Choosing it instead of a sugary drink can reduce the calories you consume, although the effect depends on what else you eat and drink. Water also supports normal hydration; it does not melt fat or remove stored calories.

How to use it: Keep water available at meals, at work or when you are out. If you regularly buy sweetened drinks, try replacing one you usually have with water rather than forcing yourself to drink when you are not thirsty.

Evidence: A 12-month analysis of women taking part in a weight-loss study found that increases in water intake were associated with weight and body-fat loss. The analysis was observational with respect to water intake, so it cannot prove that water alone caused the loss.

2. Unsweetened tea

How it may help: Tea brewed without sugar or other caloric additions contains very few calories. Its main advantage for weight loss is that it can replace a sweetened drink; there is no need to rely on claims that tea directly causes weight loss.

How to use it: Brew your preferred tea in water and drink it hot or chilled without sugar, honey or syrup. Check bottled tea labels, since a drink marketed as tea can still contain added sugar. If caffeine affects your sleep or makes you jittery, choose a decaffeinated option.

Evidence: The evidence listed here does not establish that unsweetened tea by itself produces lasting weight loss. Its practical benefit is primarily the possible calorie reduction when it replaces a higher-calorie beverage.

3. Black coffee

How it may help: Plain black coffee contains very few calories. Replacing a sweetened coffee drink with it can lower your drink's calories; any short-lived effect caffeine may have on appetite does not establish lasting weight loss.

How to use it: Brew coffee without sugar or syrup. If you prefer milk, add an amount you enjoy and account for it as part of the drink. Avoid using coffee to push through fatigue or as a substitute for regular meals.

Evidence: The studies listed here do not establish that black coffee itself causes weight loss. The more dependable reason to choose it is the potential difference between a plain coffee and a calorie-rich alternative.

4. Unsweetened sparkling water

How it may help: Plain sparkling water provides the bubbles some people enjoy in soda without the sugar or calories. Its value comes from what it replaces, not from the carbonation.

How to use it: Choose plain sparkling water or a flavored version without added sugar. Read the label: some sparkling drinks are sweetened, and products that look similar on the shelf can have different ingredients. A splash of juice adds flavor but also adds calories.

Evidence: No study listed here shows that sparkling water has a special weight-loss effect. Treat it as an alternative to still water or sugary soda, not as a weight-loss treatment. If carbonation makes you uncomfortable, still water may suit you better.

5. Infused water

How it may help: Adding fruit or vegetables to water can make it more appealing without needing a sweetened drink. The amount of calories and nutrients transferred into the water is not the same as the amount in the whole produce, so infused water should not be counted as though you ate all the fruit or vegetables.

How to use it: Try this simple cucumber infusion:

Ingredients

2 cups (480 mL) drinking water
2 tablespoons (30 mL) sliced cucumber

Steps

Wash the cucumber under running water and slice it.
Add the cucumber to the water in a clean, covered container.
Refrigerate for 1–2 hours to let the flavor develop.
Drink within 24 hours, keeping the infusion refrigerated until serving.

Evidence: No study listed here tests infused water for weight loss. It can still be useful if the flavor helps you choose water instead of a higher-calorie drink.

6. Plain low-fat milk

How it may help: Unlike the other choices, plain milk supplies calories as well as protein and other nutrients. It may be a practical choice when you want a nourishing drink, but adding it on top of your usual intake will not automatically support weight loss.

How to use it: Choose plain rather than sweetened or flavored milk, and consider it alongside the rest of your meals and drinks. If you avoid lactose, lactose-free milk or an unsweetened, fortified soy drink may be an alternative.

Evidence: The studies listed here do not establish that drinking milk causes weight loss. Whether it fits your plan depends on the amount you drink and what it replaces, as well as your nutritional needs.

Which drinks should you limit for weight loss?

Start with drinks that add calories without being particularly satisfying for you. These may include regular soda, sweetened tea, fruit drinks, sweetened coffee drinks and energy drinks. Check the full serving you actually drink, not just the number on a small labeled serving.

Juice and smoothies can provide nutrients, but they also contribute calories; a large smoothie is not automatically a lighter choice than a meal. Alcoholic drinks contribute calories too, and mixers can add more. Sports drinks can be useful in some exercise situations, but they are not necessary as an everyday weight-loss drink.

Be cautious with products sold as weight-loss or detox drinks. In a 12-week randomized vinegar beverage trial, participants receiving vinegar had lower body weight than those receiving a placebo, but this limited evidence does not make vinegar a proven or necessary weight-loss method. Drinking vinegar straight can irritate the throat and damage tooth enamel.

Similarly, a randomized trial of green tea kombucha found no additional weight loss compared with the control group when both groups followed a calorie-restricted diet. Kombucha is not a weight-loss requirement, and some products contain added sugar.

For more on detox for weight loss, the important distinction is that hydration supports normal body functions; the liver and kidneys do most detoxification, while the lungs and gut help eliminate waste. No drink needs to cleanse the body for weight loss to occur.

How much should you drink for weight loss?

There is no single amount of water that guarantees weight loss. Drink regularly with meals and when thirsty, and adjust for circumstances such as heat or physical activity. You may need more fluid when you are losing it through sweat or illness, but forcing large amounts of water in a short time can be dangerous.

The calorie change matters more for weight loss than a particular water target. Think about what you usually drink, identify a higher-calorie option you could replace, and choose an alternative you enjoy. Avoid compensating automatically with extra food or other sweetened drinks.

To estimate your daily calorie needs, consider your age, height, weight and activity level. The calorie calculator can help with that estimate; it is a starting point, not a prescription or a guarantee of weight loss. A sustainable eating and activity plan matters more than any one beverage.

Who should be careful, and when should you see a doctor?

Talk with a clinician before changing your fluid intake substantially if you have kidney disease or heart failure, have been told to limit fluids, or take diuretics. If you have diabetes and use insulin or other medication that can lower blood sugar, ask how changes to your eating and drinking routine may affect your care; do not stop or change medication on your own.

If you are pregnant, breastfeeding, or choosing drinks for a child, ask a clinician about individual nutrition and caffeine needs rather than starting a restrictive weight-loss plan. People with reflux, a sensitive bladder, anxiety or sleep problems may also find that caffeine makes symptoms worse.

See a doctor if you are losing weight without trying, are unusually thirsty, or have concerns about your weight or eating habits. Seek urgent medical help for severe thirst accompanied by confusion, repeated vomiting or trouble breathing.
