Surprising Findings
Sucralose, a non-nutritive sweetener with no glucose, triggered significant insulin spikes at peak response levels in the same way as glucose and fructose.

Non-nutritive sweeteners elicit cephalic-phase insulin release in humans independent of carbohydrate content, leading to postprandial hypoglycemia and increased carbohydrate craving.
Even artificial sweeteners that don’t contain sugar can make some people’s bodies release insulin just from tasting them.
When people taste something sweet—even if it doesn’t have sugar—their body sometimes starts releasing insulin right away, just from the taste.
