Adding Salt to Coffee May Help With Weight Loss, Study Finds

If you’re trying to cut calories without giving up your morning coffee, you’re not alone. Many people wonder if there’s a way to enjoy black coffee while still reducing fat intake or suppressing appetite. One recent study suggests a surprising — and simple — tweak might help.

According to research by UK scientist Andy Browning, adding a small amount of salt to your coffee can both reduce perceived bitterness and potentially support weight loss goals — as long as you don’t add sugar or cream. The key is getting the balance right so no extra calories are introduced.

What the Science Says About Salt in Coffee

The claim originates from a study reported by Russian health media on February 19, citing UK-based researcher Andy Browning. His theory is that adding salt to coffee in the right proportion for the amount of water used can balance flavours without adding calories. This approach not only helps with taste but aligns with low-calorie diet strategies.

This idea has also been backed by American scientists, who suggest that salt can enhance coffee’s natural flavours while muting its bitterness. The result? A smoother, more palatable cup of black coffee — ideal for those avoiding milk, sugar, or flavoured additives.

How Salt Might Help with Weight Loss

While salt itself doesn’t burn fat, it may contribute to weight loss indirectly. By improving the taste of black coffee, salt makes it easier to stick with unsweetened, low-calorie coffee options. Black coffee has virtually no calories, and drinking it plain is a common strategy for cutting energy intake. If salt allows you to enjoy black coffee more, you’re less likely to add high-calorie extras like cream, milk, or flavoured syrups.

In contrast, some experts previously recommended adding substances like olive oil or cream to coffee for various health or energy reasons — but those additions come with extra calories. Salt, in tiny amounts, offers a calorie-free flavour modifier.

The Right Amount: How to Add Salt to Your Coffee

The optimal amount of salt depends on the volume of water used in your coffee. While the original report does not specify an exact measurement, the principle is to add just enough salt to balance flavours without making the coffee taste salty. For a standard cup (around 240ml or 8oz) of brewed coffee, a common home method is to add a small pinch — roughly 1/32 to 1/16 of a teaspoon — of table salt. That’s just enough to reduce bitterness and smooth out the cup.

The exact balance is subjective and should be adjusted based on your taste and the coffee’s roast level or origin. The goal is to enhance the coffee’s natural attributes, not overpower them. Salt can also help suppress the metallic or overly acidic notes that some single-origin or light-roast coffees can have.

Frequently Asked Questions

Does adding salt to coffee really help with weight loss?

Salt doesn’t directly cause weight loss, but it can make black coffee more palatable, helping you avoid adding high-calorie ingredients like sugar, milk, or cream. By encouraging you to drink black coffee — which has almost no calories — salt may indirectly support weight loss efforts.

How much salt should I add to my coffee?

There’s no universal measurement, but the idea is to add just a small pinch — roughly 1/32 to 1/16 of a teaspoon per standard 8oz (240ml) cup — to balance flavour without making it taste salty. Adjust based on your personal taste and the coffee’s characteristics.

Why do scientists suggest adding salt to coffee?

Salt can reduce bitterness and enhance sweetness perception in coffee, making black coffee smoother and more enjoyable. This encourages people to drink it without calorie-heavy additives, aligning with weight-loss or clean-eating goals.

Can adding salt replace milk or cream in coffee?

No, salt does not replace the texture or creaminess of milk or cream. But it can improve the taste of black coffee enough that some people find they need fewer additives — which helps reduce calorie intake.

Is this method backed by solid scientific studies?

The original claim comes from UK researcher Andy Browning, cited by Russian health media, and has been echoed by some American scientists. While not part of a large clinical trial, the idea is supported by sensory science principles around taste modulation.

Conclusion: A Pinch Could Make a Difference

If you’re aiming for a healthier coffee routine without sacrificing flavour, a small amount of salt might be worth trying. It won’t melt away fat on its own, but it could help you enjoy black coffee more — making it easier to skip the calories from cream and sugar. As with any dietary change, the real benefit comes from what you don’t add to your cup.
