Drink 375ml a day, calories 168cal, and gain 8 kg a year.

If you can't live without coke for a day, you'd better do more exercise to consume excess calories. Because one can a day can make you gain 8 kilograms a year later. Even more frightening is that the cola you drink will not only make you feel full, but also make you eat more food because of its strong taste. Not only cola, but also other soft drinks, root beer and so on.

Suggestion: If you really can't give up coke, you'd better choose low-calorie coke instead of sugar.
