When it comes to weight loss everyone knows that it would be for the best to stay away from drinking the regular sodas that are full of sugar. One popular way to get around this is to swap the normal sugary soft drinks for the zero calorie diet sodas, but is it actually a better alternative ? well, the answer is complicated and here’s why.

Why It Can Be Bad For You

Loaded With Artificial Sweeteners/Chemicals

It’s true that diet sodas are loaded with a bunch of artificial sweeteners and chemicals, but the results of many scientific studies vary greatly. The studies where mostly done on humans and laboratory rats, the studies done on humans showed no harmful effects from these artificial chemicals/sweeteners. While other studies done on laboratory rats link these artificial sugars to cancer, tumours, weight gain and thyroid issues.

Artificial sugars have a more intense flavour compared to real sugar so it makes your taste buds less sensitive to naturally sweet foods like fruit. Additionally, these artificial sugars trigger your insulin levels to rise just like real sugar.

It’s Not Calorie Free

Just so that you know diet sodas aren’t actually calorie free because although it doesn’t contain any carbs, fats or proteins the artificial sweeteners break down into methanol and amino acids which generate calories. The caloric amount is usually stated if you look at the nutrition information and normally won’t be higher than 10 calories per can.

Why It Can Be Good For You

There was a study done at the university of Colorado that showed people who drank diet soda lost an average of 4 more pounds in 12 weeks than those who drank just water. The whole study included around 300 people who already drank at least 3 diet sodas a day, but the participants were split into 2 groups: one that drank at least 2 diet sodas a day with no restriction on water and another group that drank just water.

For the 12 weeks the participants had registered dieticians and clinical psychologists to help them with weight loss. After the 12 weeks the group that drank at least 2 diet sodas a day lost an average of 13 pounds compared to an average of 9 pounds of the group that just drank water. Furthermore, the group that drank diet soda showed a much larger reduction in LDL (bad cholesterol) compared to the other group.

What Does This Study Show ?

What this study shows is that satisfying your sweet tooth with diet sodas will actually help with weight loss because the participants in the water group probably didn’t lose as much weight because they ate more sugary foods as a result of giving up diet soda for 12 weeks. Although drinking at least 2 diet sodas a day is a bit excessive so if you want to drink diet soda while your on a diet try to limit it to no more than 1 a day.


Now if you don’t really have a sweet tooth then there really is no need for you to drink diet sodas. In fact if you can drink just natural beverages like coffee and tea that would be more beneficial because they actually hydrate your body unlike sodas, but on the occasion if you want something sweet drinking a diet soda is a better choice than eating sweets or full fat sugary foods.

  1. Hi,

    I’ve drank diet soda for many years because it supposedly has zero or very low calories compared to normal soda. Which is true because diet soda contains artificial sweeteners and other chemicals. However, I believe soda is just bad in general ! I’ve now lowered my consumption of all soda and that was the best thing for my body, all I do now is drink water all day long.

    Thanks for the post, cheers.

    1. If you can drink just water that would be for the best, but other’s find it hard to give up soda all together so diet sodas can be beneficial if it’s limited to just one a day.
