Coconut water has 19 kcal and 2.6 g sugar per 100 g. A natural electrolyte source with potassium ~250 mg per 100 ml — comparable to a banana. Not a calorie-free hydration option; track the sugar like any juice.
How should I track Coconut water?
Liquid calories from Coconut water 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.
