Good to know: Visualization assumption: 1 teaspoon of granulated sugar ≈ 4 g. Sugar energy uses 4 kcal/g; actual spoon weight varies. Educational food-planning arithmetic, not medical advice. Food labels and estimates can vary. Use a clinician or registered dietitian for a personalized plan, especially for children, pregnancy, breastfeeding, medical conditions, or an eating-disorder history.
