In no case should soft drinks replace water as a hydration drink for the proper functioning of our body.

The risks of consuming diet soda
Sugar-free sodas are soft drinks that don’t contain any sugar and instead contain alkaline sweeteners, such as aspartame, saccharin or cyclamate. Although sugar-free soft drinks contain no calories, the sweeteners favor the absorption of sugar into the intestine.
In addition, they promote insulin secretion in the same way as sugary sodas. Therefore, blood sugar decreases, thereby causing a feeling of hunger.
Sweeteners also affect the intestinal flora, modifying the bacteria in the body. As a result, this also produces dysbiosis and glucose intolerance.

Diet soda and weight
Researchers are increasingly studying the relationship between diet soda and weight. The studies aim to figure out if sugar-free soft drinks can cause weight gain, as it’s a subject of such great controversy.
The latest published study, Sugar and artificially sweetened beverages linked to obesity: a systematic review and meta-analysis, shows an association between soda consumption and obesity.
However, it’s important to clarify that this study doesn’t distinguish between sugary sodas and sugar-free diet sodas. The results show that the consumption of soft drinks, whatever their sugar content, is higher in people with obesity.
Other studies suggest that sugar-free drinks, apart from raising the risk of obesity, may increase the chance of cardiovascular disease. However, there is no clear evidence as to why this occurs.
On the other hand, there are studies, like this one by Plos One, that show the link between the consumption of diet soda and a greater amount of abdominal fat. According to this study, diet soda may not be effective as a measure to control weight.
Why could diet soda make you gain weight?
The compensation effect
Sugar-free drinks may not cause weight gain on their own, but they are related to unhealthy lifestyle habits.
You probably think that the calories you are going to save in that soda can be replaced by consuming more caloric food. For example, compensating for eating a hamburger with fries by drinking diet soda is not a reliable way to control your weight.
They can increase hunger
To reiterate, these sodas can trigger the feeling of hunger in those who consume them.
In some cases, the insulin high you experienced when you consume sucralose is accompanied by a decrease in glucose levels.
This means that your body reacts to sugar-free soft drinks the same way it reacts to regular soda. The only difference is that the sugar doesn’t actually enter the body.
Sweetness causes addiction
It has been shown that eating very sweet foods, whether or not they provide calories, frequently activates brain areas related to pleasure and reward, leading to an addiction to very intense flavors and sensations. The effects of sweet foods on the brain cause the same sensation as using a drug, so you tend to want to eat more and more sugar.
Conclusion
If you want to lose weight, it seems logical to replace sugary sodas with sugar-free sodas. So far, it’s been shown that, in moderate quantities, they are safe and don’t contain calories.
However, science shows that drinking diet soda regularly doesn’t help weight control since it can cause you to eat more and gain more abdominal fat.
Weight gain is quite complex and you can’t blame a single group of foods, products, or even sugar. With that said, your main beverage should be water, both during and between meals.
However, what if you want to have a soda? What do you choose, diet soda or regular soda? You can opt for diet soda occasionally since no negative effects are found when consumed in small quantities.
