How it works

When women eat lots of sugary foods over time, their bodies become less able to control blood sugar because their liver releases more glucose and their muscles don’t respond as well to insulin. Men’s bodies adjust better, so their blood sugar doesn’t rise as much. This difference is likely tied to...

Most probable mechanism

In Simple Terms

In women, long-term eating of foods that quickly raise blood sugar causes the liver to release more glucose and the body’s tissues to become less responsive to insulin over time, leading to steadily higher blood sugar after meals. In men, these changes don’t happen as much, so their blood sugar stays more stable.

Causal chain

Chronic exposure to high-glycemic-index carbohydrates increases hepatic glucose production through upregulated gluconeogenic enzyme activity.

Indirect evidence only

which leads to

Peripheral insulin sensitivity declines in adipose and skeletal muscle tissue in response to sustained postprandial hyperglycemia and elevated free fatty acid flux.

Indirect evidence only

which leads to

Estrogen-dependent signaling pathways modulate the rate of insulin resistance development in adipose tissue and liver, resulting in slower adaptation to metabolic stress in women compared to men.

Indirect evidence only

which leads to

Delayed suppression of glucagon secretion and reduced insulin-mediated suppression of hepatic glucose output occur in women under prolonged high-glycemic load, amplifying postprandial glucose elevation.

Similar Assertions

In people at high risk for type 2 diabetes, women have higher blood sugar levels after eating high-glycemic index foods than low-glycemic index foods, and this difference grows larger over 12 weeks. Men do not show this difference between the two diets.

90%

Among adults at high risk for type 2 diabetes, eating a Mediterranean diet high in glycemic index for 12 weeks raises average blood glucose levels by 37% in women, but not in men, when compared to a similar diet with low glycemic index and equal amounts of carbohydrates and fiber.

78%

Men who are overweight or obese release more insulin after eating a high-fat meal than men with normal weight, even when their blood sugar levels rise the same amount, suggesting differences in how their bodies regulate insulin that are not due to blood sugar changes.

72%

If you have type 2 diabetes, swapping your usual breakfast for a low-carb, high-fat one can help keep your blood sugar more stable all day long, without making your lunch or dinner blood sugar worse.

70%

For adults with type 1 diabetes, changing the glycemic index of foods does not meaningfully alter blood glucose patterns over four weeks, whether they eat a lower or higher amount of carbohydrates.
