Plain brewed coffee has near zero calories — only 2 kcal per 100 g. An umbrella review of 201 meta-analyses (Poole et al., BMJ 2017) found 3–4 cups per day linked to a 17% lower all-cause mortality. The calories come from any milk, sugar, or syrup added — those are what to track.
How should I track Coffee (Black)?
Liquid calories from Coffee (Black) are easy to overlook because drinks do not trigger the same fullness signals as solid food. A meta-analysis (Wehling & Lusher, Am J Clin Nutr 2021) confirmed that people underreport beverage intake more than solid food. Most people pour 30–50% more than the label serving size without realizing it. Use a kitchen scale to weigh your glass or bottle once — you will know your exact pour going forward. This one calibration step can save you from hundreds of untracked calories per week.
