Diet drinks may make you fatter

With the development of economy and the improvement of living standards, obesity has become a public health problem all over the world

In order to reduce the impact of sugar on health and obesity, more and more people are starting to consume artificial sweeteners instead of normal sugars.

However, the health effects of artificial sweeteners remain highly controversial, and there is no clear consensus on their effects on appetite, glucose metabolism, and body weight

Recently, in a research report published in the international journal "JAMA Network Open", scientists from the University of Southern California and other institutions found through research that beverages containing the artificial sweetener sucralose may increase the number of women and women.

Over 40% of adults in the United States use NNS as a calorie-free way to satisfy a sweet tooth, and in some cases it often helps people achieve weight loss goals

Researcher Katherine Page, Ph.

To study the effects of NNS, Page and colleagues studied 74 participants who had 300 milliliters of a sucrose (table sugar)-containing beverage during 3 different follow-up visits and were given a NNS sucralose-based beverages or water served as controls

Over the next two hours, the researchers analyzed three parameters, which they used fMRI imaging to analyze in the brains responsible for appetite and food when participants responded to pictures of high-calorie foods such as hamburgers and doughnuts Which areas of cravings were activated, blood levels of glucose, insulin and other metabolic hormones, and the amount of food consumed in the self-service snacks provided by the researchers at the end of each "short session

Imaging findings showed that women and obese people had increased activity in areas of the brain responsible for food craving and appetite after consuming sucralose-containing beverages, compared to consuming beverages containing real sugar

Finally, female participants ate more at self-service snack bars after consuming the sucralose-containing beverage, while male participants ate no more snacks.

By studying different groups, the researchers found that women and obese people may be more sensitive to artificial sweeteners

The findings suggest that women and obese individuals may be particularly sensitive to different neural responses to sucralose-based beverages compared to sucralose-containing beverages
