Drinking Soda Can Make You Gain Weight, According to a New Study

If you are one of the 40% of people who've been substituting sweeteners for sugar—specifically, drinking diet soda instead of regular—new brain science reveals this could be producing the exact opposite effect from what you want. A riveting current study has identified a link between diet soda and calorie intake… and the scientific explanation is likely to make you think.

Keep reading to learn about this study that focused on diet soda and weight gain, recently published in the journal of Nutrition, Obesity, and Exercise.

The Neuropsychology of Soda Drinking

Led by a group of researchers studying neuroscience, obesity, and medicine at the University of Southern California, this learn about engaged 74 healthy participants between the ages of 18 and 35 years old. Participants' body mass index (BMI) was once used to determine whether they were of normal weight, overweight, or obese.

The researchers report their goal was to "examine neural reactivity to different sorts of high-calorie food cues (i.e., sweet and savory), metabolic responses, and eating behavior" after some of the participants consumed sucralose (an artificial sweetener), while others consumed a sugary drink and any other group drank only water.

The Metrics

Between March 2020 and March 2021, the participants reported three times for the research team to collect their data. The participants underwent magnetic resonance imaging (MRI) of the brain and had their blood taken at baseline after a 12-hour fast, as well as 10, 35, and 120 minutes after they received one of three beverages: A drink containing sugar (approximately six tablespoons diluted in 10 ounces of water that provided 300 calories), artificial sweetener (of an amount whose sweetness was equal to the sugar, additionally dropped into 10 ounces of water), or plain water.

Then, the researcher report they measured participants' levels of glucose, insulin, ghrelin (known as the hormone that stimulates hunger), and leptin (a hormone that regulates food intake and energy expenditure). At that point, the researchers introduced the participants with a buffet meal that they were invited to enjoy freely.

Fascinating Results

Perhaps unsurprisingly, sugar drinks were associated with higher production of glucose (blood sugar), insulin, and hormone levels that indicated a more satiated appetite.

Interestingly, the results show that calorie consumption increased significantly among female participants, and those who were obese, when they'd been part of the diet drink-consuming group.
