The Claim
In adult women, a low-glycemic-index diet increases insulin sensitivity by more than 20% compared to a high-glycemic-index diet, as measured by euglycemic clamp.
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.
In adult women, eating foods with a low glycemic index results in a more than 20% increase in insulin sensitivity compared to eating foods with a high glycemic index, as measured by euglycemic clamp.
See the scientific wording
In adult women, a low-glycemic-index diet increases insulin sensitivity by more than 20% compared to a high-glycemic-index diet, as measured by euglycemic clamp, indicating that glycemic index directly influences whole-body insulin action.
Eating carbohydrates that release sugar slowly keeps blood sugar from spiking after meals, which means the pancreas releases less insulin. Lower insulin levels allow fat to be broken down more easily and prevent insulin receptors in muscle and liver from becoming less responsive. This lets insulin work better to pull glucose into cells, improving how the body uses insulin overall.
What the research says
1 studyWomen who ate carbs that don’t spike blood sugar quickly became more responsive to insulin — meaning their bodies used insulin better to control blood sugar — and this improvement was more than 20%, exactly as the claim says.
