Diet sodas inherently have fewer calories than most traditional sugar sweetened drinks. (But they aren’t exactly filled with healthy nutrition either.) If you were going to drink a sugary soda, then a diet soda may be a good alternative. However, it’s not going to be better than water—which contains no calories.
Cons of Drinking Diet Soda
Even if a product does not contain sugar or calories, it can still contribute to gaining weight. In fact, the term ‘diet soda’ is a bit of a misnomer as many people who drink it are likely to gain weight rather than lose it. This may be related to the appetite-stimulant properties of most artificial sweeteners. Since obesity and weight gain are often considered to be risk factors for diabetes, diet soda isn’t doing anyone any favors along those lines.
Blood Sugar Spikes
Products that don’t contain natural sugar still have the potential to spike the blood sugar. Sucralose (brand name Splenda) is an artificial sweetener that may raise blood sugar in some people, particularly if carbohydrates are consumed afterwards.
Links with Diabetes
Although diet sodas may cut carbs and calories, they also may be increasing the risk factors related to developing diabetes. One study of more than 65,000 women over 14 years showed that those who regularly consumed sweetened beverages (with sugar or artificial sweeteners) were at a higher risk of developing type 2 diabetes.
