Sugary drinks are among the most fattening items you can put into your body.
This is because your brain doesn’t measure calories from liquid sugar the same way it does for solid food (1Trusted Source).
Therefore, when you drink soda, you end up eating more total calories (2Trusted Source, 3Trusted Source).
Sugary drinks are strongly associated with obesity, type 2 diabetes, heart disease, and many other health problems (4Trusted Source, 5Trusted Source, 6Trusted Source, 7Trusted Source).
Keep in mind that certain fruit juices may be almost as bad as soda in this regard, as they sometimes contain just as much sugar. Their small amounts of antioxidants do not negate the sugar’s harmful effects (8Trusted Source).
