The Claim
In adult women, a low-glycemic-index diet reduces average glucose and insulin levels by approximately 40% compared to a high-glycemic-index diet, indicating that glycemic index strongly influences postprandial and fasting metabolic responses.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Adult women who eat a low-glycemic-index diet have about 40% lower average glucose and insulin levels after meals and during fasting compared to those who eat a high-glycemic-index diet.

When slow-digesting carbs are eaten, blood sugar rises gently and stays steady, so the pancreas releases less insulin. Lower insulin lets fat cells release more fatty acids into the blood, which muscles and the liver burn for energy instead of sugar. This also makes the body more responsive to insulin, so it needs less of it to keep blood sugar low.
What the research says
1 studyThis study found that when women ate carbs that digest slowly (low-GI), their blood sugar and insulin levels dropped by about 40% compared to when they ate carbs that digest quickly (high-GI)—even when they ate the same amount of carbs. So yes, choosing low-GI foods really does help lower blood sugar and insulin.
