Per 100g
Source: Web research, March 2026.
Iced coffee contains 30 calories per 100g, but a standard medium (16oz/473ml) serving comes out to about 142 calories, primarily from added sugar (26g of sugar per medium serving). The macros are minimal on their own: 0.5g protein, 5.9g carbs, and 0.5g fat per 100g. What makes iced coffee the go-to morning drink for millions of people is the caffeine. Iced coffee made with brewed coffee provides a meaningful caffeine hit that sharpens focus, boosts workout performance, and supports fat burning during training. Keep it unsweetened and black (or with just milk) and it is one of the lowest-calorie ways to start the day. Add syrups and you can spike it to 400+ calories fast.

Health Benefits of Iced Coffees
Iced coffee is one of the most popular pre-workout and morning performance drinks for good reason. The caffeine from brewed coffee improves mental focus, increases reaction time, and is one of the most well-researched ergogenic aids in sports nutrition. Studies consistently show caffeine boosts endurance performance and can increase fat oxidation during exercise, helping you burn more fat during cardio sessions.
Black iced coffee or iced coffee with just a splash of milk is virtually calorie-free, making it one of the smartest beverages for calorie control. The coffee base also provides antioxidants, particularly chlorogenic acids, that are linked to improved insulin sensitivity and reduced inflammation.
The problem with most commercial iced coffees is the added sugar and syrups. A medium sweetened iced coffee from a coffee chain can pack 26g of sugar and 142 calories. For weight loss and performance, stick to unsweetened iced coffee or use a small amount of zero-calorie sweetener and a splash of milk to keep calories low while still enjoying the ritual.
Dietary Considerations
Plain iced coffee is vegan, gluten-free, and essentially calorie-free when unsweetened, making it compatible with virtually every dietary approach including keto. The moment you add syrups, flavored creamers, or sweetened milk, the carb and calorie count increases significantly. For weight loss, black or lightly sweetened iced coffee is one of the best calorie-free beverage choices. For keto, stick to unsweetened iced coffee with heavy cream or keto-friendly sweeteners. Avoid pre-made bottled iced coffees, which are often loaded with added sugar.
