# Proffee: Does Adding Protein to Your Coffee Actually Do Anything? The Australian Numbers | OzCal

> Proffee is the protein-coffee trend of 2026. A regular 240 mL flat white already carries about 7 g of protein for 482 kJ, because the protein is in the milk. A scoop of protein powder adds roughly 400 to 500 kJ on top. Most Australians already meet their protein needs, so for most people proffee is optional, not a fix.

# Proffee: does adding protein to your coffee actually do anything?

**The short answer.** Proffee is protein coffee, the drink trend of 2026. The part the marketing skips: a regular flat white already has about **7 g of protein** for **482 kJ**, because the protein comes from the milk, not the coffee. A scoop of protein powder adds roughly **400 to 500 kJ** on top. Most Australians already meet their protein needs, so for most people proffee is optional. It earns its place if you train, are over 70, or skip breakfast. The only way to judge a bottled one is the kilojoule figure on the panel.

## What proffee is, and why 2026

Proffee is a blend of the words protein and coffee: an espresso, long black or iced coffee with protein added, either a scoop of powder, a protein milk, or a ready-to-drink protein latte. It started as a gym-bag hack and went mainstream this year, with instant protein lattes on supermarket shelves, protein espresso drinks in the chiller, and protein options on cafe menus. Market researchers now rank protein coffee among the fastest-growing functional-drink categories of the year.

The idea is sound on paper. Coffee is a daily habit for most Australians and breakfast is usually the lightest protein meal of the day, so adding protein to a drink you already buy is an easy win. The question is whether the version in your hand is delivering protein, or just charging more for a milkshake with a shot in it.

## Your flat white already has protein

The protein in any milk coffee comes from the milk, not the coffee. A long black is under 20 kJ and no protein. Add milk and the number moves.

| Milk (240 mL flat white) | Energy | Protein |
|---|---|---|
| Skim | 300 kJ | ~7 g |
| Reduced fat | 370 kJ | ~7 g |
| Oat | 454 kJ | ~2 g |
| Full cream | 482 kJ | ~7 g |
| Soy | 499 kJ | ~6 g |
| Almond | 218 kJ | <1 g |

Skim keeps the protein while dropping the energy, the best protein-to-energy deal of the common cafe milks. Almond is lowest in kilojoules but has almost no protein, so an almond latte is close to a protein-free coffee. A large 360 mL flat white carries about 11 g of protein on its own. Two milk coffees a day is most of a protein snack you were not counting. Full guide: https://ozcal.com.au/kilojoules/flat-white

## DIY proffee: what a scoop actually adds

The classic home version is iced coffee with milk and a scoop of protein powder. The milk does real work: a cup of regular milk already brings about 8.5 g of protein for roughly 700 kJ, and skim keeps that protein for closer to 300 kJ. A scoop of powder on top typically adds around 20 to 25 g of protein and about 400 to 500 kJ, depending on the brand.

That can be a genuinely strong drink, near 30 g of protein with skim milk and a scoop. But it is not free and it is not magic. If you already eat enough protein across the day, the scoop is extra kilojoules and extra cost doing a job your lunch was going to do anyway. If your breakfast is usually just coffee, it is one of the easier ways to turn a drink into something closer to a meal.

If the goal is cheap protein rather than a protein label, a scoop of powder is rarely the best value. Tinned tuna, eggs, milk and legumes cost far less per gram of protein: https://ozcal.com.au/kilojoules/cheapest-high-protein-foods-australia

## Is it worth it? The honest answer

For most Australians, proffee is a nice-to-have, not a need. The 2023 national survey found **98.5% of adults already meet their protein requirement**, with the median man eating about 1.5 times his recommended intake and the median woman about 1.6 times hers. If you are in that 98.5%, adding protein to your coffee does little beyond what your meals already do. Full picture: https://ozcal.com.au/blog/how-much-protein-do-you-need-australia

The real exceptions: regular resistance or endurance training, being over 70 and holding on to muscle, pregnancy and breastfeeding, or genuinely struggling to eat in the morning. In those cases, building protein into a drink you were having anyway is a sensible, low-effort habit. For everyone else, proffee is a preference, not a fix, and the bigger national gap is fibre, not protein.

## How to read a protein coffee

Two numbers on the panel settle it: **protein per serve** and **energy (kilojoules) per serve**. A good one gives a decent slug of protein for an energy figure not far off a normal milk coffee. A weak one is a flavoured milk drink with a small protein claim and a flat white's worth of kilojoules or more. Australian products must show kilojoules by law, so there is nothing to convert.

Rule of thumb: at least 15 g of protein under about 800 kJ is pulling its weight; under 10 g of protein and over 1,000 kJ is mostly a milkshake. The same test works for protein cereals, bars and yoghurts. Plain Greek-style yoghurt brings about 9 g of protein per 100 g for roughly 400 kJ and no marketing, which quietly beats many of the protein products beside it.

## Know your own number

Whether proffee is worth it comes down to how much protein you are already getting, which the trend cannot tell you. A week of logging usually answers it. OzCal shows protein next to kilojoules for every food and drink you log by barcode, photo or voice, from 94,000+ Australian and New Zealand foods.

## Common questions

**Q: What is proffee?**

Protein coffee: espresso or iced coffee with added protein, from a scoop of powder, a protein milk, or a ready-to-drink protein latte. The name blends protein and coffee. It went mainstream in 2026 as brands launched protein coffee products across Australian supermarkets and cafes.

**Q: How much protein is in a flat white?**

About 7 g in a regular 240 mL flat white with full cream or reduced fat milk, because the protein is in the milk. A large 360 mL cup has about 11 g. A black coffee has none. Almond milk drops it to under 1 g.

**Q: Is proffee worth it?**

For most Australians it is optional: 98.5% of adults already meet their protein needs and a normal milk coffee already carries about 7 g. It helps if you train, are over 70, or skip breakfast. Otherwise weigh the extra protein against the extra kilojoules and cost.

**Q: How many kilojoules does adding protein to coffee add?**

A scoop of protein powder adds roughly 400 to 500 kJ. Ready-to-drink protein lattes vary widely, from close to a flat white to close to a milkshake. The panel's kilojoule figure is the only way to know.

**Q: What is the best coffee for protein without the kilojoules?**

A skim milk flat white: about 7 g of protein for roughly 300 kJ, the best protein-to-energy ratio of the common cafe milks. Full cream keeps the protein for 482 kJ. Almond is lowest in kilojoules but has almost no protein.
