This diet soda has 2 kcal per 100 g — effectively zero. The artificial sweeteners deliver sweetness without sugar. A 17-cohort meta-analysis (Imamura et al., BMJ 2015) found artificially sweetened drinks linked to T2D too, though confounding may explain part of the signal.
How should I track Diet Cola, Aspartame, Caffeinated?
Liquid calories from Diet Cola, Aspartame, Caffeinated 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.
