Millions of people reach out for diet soda every day to reduce sugar intake, manage their weight, and make healthier choices. However, new research suggests that these artificially sweetened drinks may do more than satisfy sweet teeth. They may also be quietly rewiring the way the brain regulates hunger.
Artificial sweeteners have long been controversial about the possibility of cancer and poor gut health. However, some studies suggest that sweeteners like sucralose can stimulate areas of the brain involved in hunger signaling, causing dietary urges. It's not very clear whether that will actually lead to weight gain, but the idea that diet soda supports weight loss is becoming more and more complicated.
What is sucralose sugar?
When you eat or drink something with calories, such as sugar-like soda, it begins a cascade of responses designed to manage your energy. Glucose is absorbed into the bloodstream, the intestine releases hormones such as GLP-1 and leptin, and the pancreas produces insulin. Together, these signals tell the hypothalamus (the hunger control command center of the brain) that energy has arrived and is satisfied and satisfied.
(A surprising reason why I can't stop thinking about junk food.)
However, that feedback loop breaks when an artificial sweetener like sucralose enters the picture. Such changes can be observed through functional MRI scans showing relationships with hypothalamic activity and other brain regions, says Kathleen Page, an endocrinologist and director of the Institute for Diabetes and Obesity at the University of Southern California School of Medicine. “We're thinking [the activity] She says. Eating glucose causes a decrease in hypothalamic activity, which is associated with bloating. Sucralose, an artificial sweetener, appears to instead increase activity in brain regions.
