Lemonade has 52 kcal and 13.3 g sugar per 100 g. A 250 ml glass packs ~33.3 g sugar — most of the calories come from sweetening, not lemons. Homemade with less sugar tracks lower; "diet" versions use non-nutritive sweeteners.
How should I track Limeade, frozen concentrate, prepared with water?
Liquid calories from Limeade, frozen concentrate, prepared with 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.
