Why sweet taste might make you crave carbs
The cephalic phase insulin response to nutritive and low-calorie sweeteners in solid and beverage form.

When some people taste sweet things—even sugar-free ones—their body sometimes tricks itself into thinking sugar is coming and releases insulin early. This can make blood sugar drop too low, making them hungrier for carbs.
No biological mechanisms were identified in this study. This may be an epidemiological, observational, or survey-based study that reports associations rather than proposing causal biological pathways.

Some people’s bodies react to sweet tastes by releasing insulin right away—even if it’s fake sugar—but others don’t, and we don’t yet know why.
Even though tasting artificial sweetener makes some people’s bodies release insulin, it doesn’t make them feel hungrier or change their blood sugar right after—so the insulin spike doesn’t seem to do anything noticeable yet.
Non-nutritive sweeteners elicit cephalic-phase insulin release in humans independent of carbohydrate content, leading to postprandial hypoglycemia and increased carbohydrate craving.
When overweight people taste a solid sweet made with artificial sweetener (like sucralose), their bodies sometimes release insulin right away—even though there are no calories—just like when they taste real sugar.
Chewing a sweet solid (like a gumdrop) makes your body release more insulin right away than just drinking the same sweet taste, no matter if it’s sugar or artificial sweetener.
