The study that had been conducted by Carmen Piernas at the University of North Carolina found out that diet drinks, unlike soft drinks, do not boost appetite or make people consume more products containing sugars and fat.
Researchers specified that diet drinks have the same effects as water does. The study was published in American Journal of Clinical Nutrition.
The results of this research oppose the previous study that claimed the synthetic sweeteners to destabilize hormones that regulate appetite leading to the increased level of food consumption. It was also claimed that diet beverages increased the desire to eat more products containing sugar.
318 obese individuals in North Carolina were observed during the survey. These people consumed 280 and more calories through sweet beverages every day.
All study participants were divided into two groups. The first group started drinking water instead of soft drinks. For the other group, the sugary drinks were replaced by diet drinks, including Diet Mountain Dew, Diet Lipton Tea, and Diet Coke.
The volunteers reported the amount of food and water that they consumed on two separate days after the third and sixth month of the study. The experiment showed that both groups reduced their daily amounts of calories from around 2,000 and 2,300 calories to 1,500 and 1,800 calories.
People who drank diet beverages consumed approximately the same levels of sugars, carbohydrates and fat as water drinkers during the whole period of the study.
Another finding was that water drinkers started eating more vegetables and fruits after six months of the study while the diet beverages drinkers cut down the amount of desserts comparing to the beginning of the study.
In other studies, it was showed that people who consume drinks consisting of real or synthetic sugar have a higher risk of developing diabetes, depression, cardiovascular diseases or stroke. Also, the artificial sweeteners are believed to increase risk of cancer.
