Coffee beans themselves are low in calories. Here’s a detailed breakdown:

Whole Coffee Beans

• Calories: About 2-4 calories per gram.
• Serving Size: One coffee bean typically weighs between 0.1 to 0.15 grams, so each bean contains roughly 0.2 to 0.6 calories.

Brewed Coffee

• Calories: Essentially zero calories per cup (240 ml), as the brewing process extracts mostly water-soluble compounds, oils, and some acids, leaving behind most of the calories contained in the grounds.

Nutritional Breakdown (per 1 gram of coffee beans)

• Carbohydrates: Approximately 0.3 grams
• Protein: Approximately 0.1 grams
• Fat: Trace amounts (less than 0.1 grams)

Other Considerations

• Additives: Adding sugar, milk, cream, or flavorings will increase the calorie content significantly.
• Roasting: The calorie content remains consistent through different roasting levels (light, medium, dark).

Consuming coffee beans whole or brewed has negligible calorie impact, making it a low-calorie beverage option.
