How Many Calories Does Yerba Mate Have? The Truth About the Infusion and Add-ins

How many calories does yerba mate have? This question comes up often when someone swaps their morning coffee for a matero, or is looking for a drink that gives energy without weighing down their daily calorie balance. The answer is simpler than most discussions about this plant suggest: the infusion made from dried Yerba Mate leaves alone, brewed in water, has about as many calories as plain tea. Practically zero. The problem only starts with add-ins – sugar, milk, syrups or ready-made flavoured drinks, because these are what decide whether a glass of mate stays light or turns into a dessert.

How many calories does yerba mate have without add-ins

Dried Yerba Mate leaves themselves contain carbohydrates, a bit of fat and trace amounts of protein, just like any dried herb. But no one eats the dried leaves dry – we brew them with water and drink the infusion, and only a minimal amount of energy-providing substances passes from the submerged leaves into the water. In practice, a serving of pure mate infusion, without sugar or milk, is a few calories per whole glass – a negligible value in your daily balance. For comparison: black coffee without add-ins has similarly little, and so does green tea.

That’s why yerba mate has been part of diet conversations for years. It’s not that the infusion itself “burns” anything in some magical way, but that you can drink a lot of it, for a long time, without worrying about calories, while still feeling a real boost of energy thanks to the xanthines contained in the leaves. Anyone who swaps cola or sweetened coffee for plain matero really does save themselves several hundred calories a day – not because mate has miraculous properties, but because what they’re drinking simply stops being calorie-laden.

What really adds calories to a glass of mate

The infusion stays light only when it’s pure. In practice, we most often add something to it that changes the balance:

• A teaspoon of sugar is about 16 kcal, two already 32 kcal – for someone who drinks mate several times a day, this quickly adds up to several hundred calories a week.
• Honey adds a similar amount, about 20-22 kcal per teaspoon, though it also brings trace elements that sugar doesn’t have.
• 2% cow’s milk is about 50 kcal per 100 ml – if you make your mate with milk instead of water, the whole calculation changes.
• Flavoured syrups (vanilla, caramel) can add 20-40 kcal per serving, depending on the brand and amount.
• Ready-made energy shot drinks based on guarana and yerba already have their own calorie content, with sugar or a sweetener built into the recipe – that’s a different category from a classic infusion.

There’s nothing wrong with that, as long as you know what you’re doing. The problem arises when someone drinks “healthy yerba” with three teaspoons of sugar and wonders why their diet isn’t working. The calorie count comes from the add-ins, not from the leaf.

Yerba Mate vs. Coffee, Tea and Energy Drinks – A Real Comparison

If you’re looking for a reference point, here’s how it works in practice. Black coffee without sugar: a few calories per cup. Green tea: similarly, close to zero. Yerba mate with no additives: the same level. The difference only appears when you compare ready-made drinks – a can of an energy drink like cola or classic energy drink can have 100-140 kcal, mostly from sugar, and some light variants replace sugar with a sweetener, so there are fewer calories, but more caffeine and artificial additives. Yerba mate in its classic form, brewed in a matero, doesn’t have this problem, because you keep full control over the sweetness.

This is exactly why mate is often recommended as a replacement for energy drinks or sweetened coffee from a vending machine – not because it works miracles on your metabolism, but because it’s easy to keep it at zero calories while still getting a real boost of alertness.

Do flavored variants have more calories than classic yerba

Two things need to be distinguished here. Flavored dried leaves, meaning yerba leaves with added dried fruit, flowers or aroma (e.g. a variant with citrus fruits or hibiscus and blackcurrant), are still brewed in water on their own and don’t add significant calories – the addition of dried herbs or fruit peels in such a small amount doesn’t change the infusion’s balance. A different matter is a special blend, like Slim Fit, which was composed to support weight control – here too we’re talking about a water-based infusion, so the calorie count stays minimal, but the herbal composition changes.

The real difference in calories only appears with ready-made bottled drinks or flavored shots, because there the manufacturer adds sugar or a sweetening substance already at the production stage. Classic dried leaves brewed by yourself at home give you full control – you decide whether your glass stays at a few calories at most, or grows to over a hundred through additives.

How to Drink Yerba Mate to Keep the Calorie Count Low

A few practical rules that actually make a difference:

• Brew with water, not milk, if you care about keeping the calorie count low – mate with milk is a different drink, closer to a latte.
• If you need sweetness, reach for flavored dried leaves instead of adding sugar – the fruity aroma in the leaves gives the impression of sweetness without real calories.
• Watch your scoop-to-water ratio – the more dried leaves per water, the stronger the infusion, but the calorie count of the infusion itself stays negligible either way, so it’s a matter of taste, not diet.
• Avoid syrups and ready-made flavor mixes with a long list of ingredients – sugar often hides there under a different name.
• If you drink mate several times a day at work, it’s worth writing down once how many teaspoons of sugar you actually add over a week – the numbers can be surprising.

Mate in Your Diet – Where It Really Matters

If you’re counting calories throughout the day, the key is to treat mate like water, not like a liquid meal. This is a big difference compared to, say, coffee with plant-based milk and syrup, which can have more calories than a sandwich. People on a calorie deficit often discover that a few glasses of sweetened coffee or tea throughout the day eat up a large part of their daily budget before they even sit down for lunch. Swapping this habit for plain mate infusion, possibly with a bit of lemon or mint, can free up several hundred calories’ worth of room in your diet without any sacrifice in the form of hunger.

It’s also worth remembering that mate brewed several times throughout the day (as in the traditional ritual, where one matero passes between several people) stays low in calories regardless of the number of water refills – all that matters is what you add or top up along the way, not the number of rounds.

Frequently asked questions about calories in yerba mate

How many calories does a glass of plain yerba mate have?
A few calories per whole serving, about the same as plain black tea or coffee without sugar. This is a value that can be ignored in your daily balance.

Does flavored yerba mate have more calories than the classic version?
No, if we’re talking about dried leaves with added dried fruit or herbs brewed in water. Calories only increase with ready-made bottled drinks containing sweeteners or added sugar.

Is mate with milk still low in calories?
Not quite – milk adds its own calories, so this infusion stops being the equivalent of plain tea and becomes closer to a light latte.

Does drinking yerba mate instead of sweetened drinks help you lose weight?
Drinking it alone doesn’t “burn” anything, but swapping a high-calorie drink for an infusion that’s virtually fat-free and sugar-free genuinely lowers your daily calorie balance, which matters in the long run.

How much sugar can I add to mate without ruining the effect?
It depends on the rest of your diet, but the rule is simple: each added teaspoon is about 16 kcal, so it’s worth counting it the same way you would with coffee or tea.

Yerba mate as a plant, Paraguayan holly, has been brewed in plain water in a matero and sipped through a bombilla for centuries – this is the most traditional and lightest form of this drink. The calorie content of mate depends essentially entirely on what you add to the cup, not on the leaf itself.
