Answer 1

Basically, different types of sugar have slightly different amounts of calories. Coke actually has high fructose corn syrup because MURICA. HFCS has exactly 3.7 calories per gram. Assuming that all 39 grams of sugar are actually HFCS, that’s 144 calories. **The FDA allows rounding calories to the nearest 10, so it’s actually 140 calories on the bottle.** I’m not sure where you got 139 from but that’s how it works.
