I personally suggest that you drink less processed drinks outside (unless you are really thirsty), which has nothing to do with gaining weight, but these drinks all contain additives that are bad for your health. As for drinking too many cola/sprite drinks (for example, drinking one bottle a day), it will definitely affect your body's obesity and other aspects of your body.

What's more, being fat is a physical problem. Some people are not fat even if they eat and drink in the sea every day, but some people will be fat even if they don't eat or drink. As long as you are healthy.
