Brewed green tea has near zero calories — only 4 kcal per 100 g. A meta-analysis of 31 RCTs (Xu et al., Nutr J 2020) found green tea improved blood lipid markers, lowering LDL by 4.55 mg/dL. The calorie cost is essentially zero unless you add sugar or honey.
How should I track Tea, green, diet?
Liquid calories from Tea, green, diet 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.
