A 12-oz can of regular soda (about 355 mL) provides roughly 150 calories and 39 g of added sugar — about 10 tsp, per USDA/FDA references. Liquid sugar doesn’t trigger fullness the way food does, so those calories add on top of meals without reducing intake. Swapping to water, sparkling water, or unsweetened tea is one of the easiest cuts for a deficit.
Key facts:
- 12 oz soda: ~150 kcal, ~39 g sugar
