Not as big as usual. Look at the nutrition instructions (all foods and drinks are available). People who really exercise will learn to count calories first. Coke has too many calories, and most of them are made of sugar, which is the most intolerable thing for muscle exercisers. If you really want to develop beautiful abdominal muscles, you need not only a lot of exercise, but also control your diet. You can't drink sugary drinks (carbonated drinks are recruited), you can't eat too much starch, you can't eat fat (frying and cooking are not suitable), and you need to supplement protein powder. In short, the process cannot be achieved without pain.
