Does Mint Water Help With Weight Loss?

DetoxWater Editorial Team•Published November 3, 2026

Partly: mint water may support weight loss if it replaces higher-calorie drinks without extra calories elsewhere, reducing overall calorie intake. Mint itself has no proven weight-loss effect in people; relevant research has tested mint extract in mice, not mint water. Make it without added sugar, refrigerate it, and use it as part of an eating pattern you can maintain.

Does mint water help with weight loss?

Mint water can be a useful substitute for a sweetened drink, but it is not a weight-loss treatment. Its potential benefit comes from the swap: if you consume fewer calories overall as a result, that can support weight loss over time.

The swap will have less effect if you add sugar to the mint water or compensate by eating or drinking more elsewhere. If you already drink mostly plain water, switching to mint water is unlikely to make a meaningful difference to your calorie intake. Choose it for the flavor, not because it has a special effect on body fat.

How could mint water help with weight loss?

Fresh mint gives water flavor without the need for a sweetened mix. Steeped, unsweetened infused water is usually under 10 kcal per glass, although the exact amount depends on what you add and whether you consume the ingredients. Adding sugar changes the calorie content.

If the flavor makes water more appealing, mint water may help you choose it instead of a higher-calorie drink. Hydration also supports normal bodily functions, but drinking more water on its own does not guarantee weight loss or reliably suppress appetite.

The same principle applies to detox water for weight loss: the useful change is generally replacing a higher-calorie drink, not a detoxifying ingredient. The liver and kidneys do most of the body's detoxification, while the lungs and gut also help eliminate waste.

What does the evidence show about mint and weight loss?

The available evidence does not establish that mint water causes weight loss in people. In a 2023 study in mice, researchers gave an ethanol extract of Mentha canadensis to mice fed a high-fat diet. The extract group had lower body and fat-tissue weights than the comparison group.

That finding is preliminary animal evidence, not proof that a drink made by steeping fresh mint leaves has the same effect. The study did not test mint water in people, and an extract is not equivalent to a lightly infused drink. It also cannot tell us how much mint water someone would need to drink to affect their weight.

How can you use mint water for weight loss?

Make a pitcher of unsweetened mint water and use it in place of a drink that normally contributes calories. For example, have it with a meal when you would otherwise choose a sweetened drink. You do not need to drink it at a particular time of day.

Ingredients

  • 1 L water (about 4¼ US cups)
  • 8–12 fresh mint leaves (about 5 g; roughly ¼ cup loosely packed)

Method

  1. Wash the mint leaves under running water.
  2. Add the leaves and water to a clean pitcher.
  3. Refrigerate for 2–4 hours to infuse.
  4. Serve unsweetened, straining out the leaves if you prefer.

Keep the mint water refrigerated and drink it within 24 hours for the best flavor. Discard it after 2 days, or sooner if it becomes cloudy, slimy or sour-smelling; do not leave it at room temperature for more than a few hours.

Drink according to your thirst rather than forcing large quantities. If mint triggers heartburn, avoid it; if you have been advised to limit fluids, ask your clinician before increasing your intake. Use culinary mint leaves, not mint essential oil, in the water.

What results can you realistically expect?

There is no reliable amount of weight loss to expect from mint water. Results depend on what it replaces, whether that changes your overall calorie intake, and the other eating and activity habits you maintain. A pleasant drink can make a lower-calorie choice easier, but it cannot compensate for every other part of your routine.

Consider whether the swap is practical for you: keep a refrigerated pitcher available, choose it when you want a flavored drink, and notice whether you are replacing a sweetened option rather than adding another drink. You can use mint water alongside meals and snacks that help you feel satisfied; it does not need to replace food.

If you have unexplained weight changes or concerns about your weight, speak with a healthcare professional. They can help you consider your circumstances without relying on an infused drink for a result.

Frequently asked questions

Can I make mint water with sparkling water?

Yes. Use unsweetened sparkling water and fresh culinary mint, and keep it refrigerated. It may lose some carbonation while it infuses.

Can I use dried mint instead of fresh mint?

You can use dried culinary mint, although the flavor will differ. Strain it if you prefer and follow the same refrigeration and storage guidance.

Does mint water break a fast?

Unsweetened mint water contains very few calories, but it may not be allowed during a strict fast that permits only plain water. For a medical test or procedure, follow the instructions from your healthcare team.
