Caffeine, Calories & Health Basics

Does black coffee have calories if you drink a large mug instead of an 8 oz cup?

Direct Answer

Black coffee has very few calories, and a larger mug adds only a small amount unless milk, sugar, or syrup is added.

Compare serving size first. Caffeine, calories, and perceived strength change more from dose and additions than from the drink name. If the first test does not improve the cup, keep the same baseline and adjust the next most likely variable instead of changing the whole routine.
