How Many Calories Are in Black Coffee?
How Many Calories Are in Black Coffee?
Black coffee contains about 2 calories per 8-ounce cup, essentially zero. Coffee is 99% water, and the tiny amount of dissolved coffee solids (oils, proteins, trace minerals) contribute minimal calories. This makes black coffee one of the few beverages you can drink freely without affecting your calorie intake.

If you're tracking calories for weight loss or health reasons, black coffee is your friend. Here's the full breakdown of what's in your cup.

Calorie Breakdown by Serving Size
- 8 oz (1 cup) black coffee: 2 calories
- 12 oz black coffee: 3 calories
- 16 oz (grande/medium) black coffee: 5 calories
- 20 oz (venti/large) black coffee: 6 calories
- 1 shot espresso (1 oz): 1 calorie
For practical purposes, black coffee is calorie-free. The 2 calories per cup are too small to register in most diet tracking.
What About Macros?
An 8-ounce cup of black coffee contains:
- Calories: 2
- Protein: 0.3g
- Fat: 0g
- Carbohydrates: 0g
- Sugar: 0g
- Fiber: 0g
Coffee has trace amounts of protein from dissolved coffee solids, but not enough to count toward your daily protein intake.
What Adds Calories to Coffee
Plain coffee is virtually calorie-free, but what you add to it changes everything:
Milk and Cream
- 1 tbsp whole milk: 9 calories
- 1 tbsp half-and-half: 20 calories
- 1 tbsp heavy cream: 52 calories
- 2 oz (1/4 cup) whole milk: 37 calories
- 8 oz whole milk (full latte): 150 calories
Sugar and Sweeteners
- 1 tsp sugar: 16 calories
- 1 packet sugar: 11 calories
- 1 tbsp honey: 64 calories
- 1 pump flavored syrup (Starbucks): 20 calories
- Sugar-free syrups: 0-5 calories (artificial sweeteners)
Popular Coffee Drinks Calorie Comparison
- Black coffee (12 oz): 3 calories
- Coffee with 2 tbsp cream + 1 tsp sugar: 70 calories
- Latte (12 oz, whole milk): 150 calories
- Cappuccino (12 oz): 120 calories
- Mocha (12 oz): 260 calories
- Vanilla latte (12 oz): 250 calories
- Frappuccino (12 oz): 300-500 calories
The calories in coffee drinks come almost entirely from milk, sugar, and flavorings, not the coffee itself.

Does Coffee Help You Lose Weight?
Black coffee won't directly cause weight loss, but it supports weight management in several ways:
1. Appetite Suppression
Caffeine can temporarily reduce hunger and delay the urge to eat. Some people drink black coffee in the morning to extend their fasting window.
2. Metabolism Boost
Caffeine increases metabolic rate by 3-11%, helping you burn slightly more calories throughout the day. The effect is modest but measurable.
3. Enhanced Fat Burning During Exercise
Caffeine mobilizes fat from fat tissue and increases adrenaline, which can enhance performance and fat burning during workouts.
4. Zero-Calorie Beverage Option
Replacing high-calorie drinks (soda, juice, sugary coffee drinks) with black coffee saves hundreds of calories daily without feeling like deprivation.
That said, coffee isn't a magic weight-loss solution. The biggest impact comes from what you don't add to it.
Does the Roast Level Affect Calories?
No. Light, medium, and dark roasts all have the same calorie content, about 2 calories per 8-ounce cup. Roasting changes flavor, not calorie content.
The myth that dark roast has fewer calories likely comes from the fact that darker beans weigh slightly less (more moisture is roasted out). But by volume, they're identical in calories.
Does Brew Method Change Calorie Content?
Barely. Different brewing methods extract slightly different amounts of coffee solids, but the calorie difference is negligible:
- Drip coffee: ~2 calories per 8 oz
- French press: ~2-3 calories (more oils extracted)
- Espresso: ~1 calorie per shot
- Cold brew: ~3-5 calories per 8 oz (higher concentration)
- Pour over: ~2 calories
French press and cold brew might have marginally more calories because they extract more coffee oils, but we're talking about 1-2 extra calories per cup, not worth tracking.
Coffee on Intermittent Fasting
Black coffee is considered fasting-friendly by most intermittent fasting protocols. The 2 calories per cup won't break your fast or spike insulin.
However, adding cream, milk, or sugar will break a fast because they trigger an insulin response. If you're fasting for metabolic benefits, stick to black coffee (or coffee with zero-calorie sweeteners if you must).
Frequently Asked Questions
Does adding milk to coffee make it unhealthy?
No. Milk adds calories, protein, and calcium. Whether that's "unhealthy" depends on your goals. If you're trying to lose weight, milk adds calories. If you're trying to get more protein and calcium, milk helps.
How many calories in a Starbucks coffee?
A Starbucks Pike Place brewed coffee (grande, 16 oz) has 5 calories black. But a grande latte has 190 calories, and a grande mocha has 370 calories. The coffee itself is still low-calorie, the add-ins are what matter.
Can I drink unlimited black coffee on a diet?
From a calorie perspective, yes. But excessive caffeine (more than 400mg/day, or about 4 cups) can cause jitters, insomnia, and digestive issues. Stick to moderate intake.
Does instant coffee have the same calories as brewed coffee?
Yes, instant coffee has about 2 calories per 8-ounce cup when prepared according to package directions. It's essentially the same as brewed coffee.
Why do some nutrition labels say coffee has 0 calories?
The FDA allows foods with fewer than 5 calories per serving to be labeled as "0 calories." Since coffee has 2 calories, it often rounds down to zero on nutrition labels.
