Benefits and Risks of Intermittent Fasting

FAQ About Benefits and Risks of Intermittent Fasting

Does intermittent fasting improve insulin sensitivity?

Yes, intermittent fasting has been shown to improve insulin sensitivity, which is the body's ability to use insulin effectively to regulate blood sugar levels. Insulin is a hormone produced by the pancreas that helps move glucose (sugar) from the bloodstream into the body's cells to be used as energy.

When insulin sensitivity is impaired, the body's cells become less responsive to insulin, leading to high blood sugar levels and a risk of developing type 2 diabetes. Intermittent fasting has been shown to improve insulin sensitivity by reducing insulin levels during fasting periods and increasing insulin sensitivity during feeding periods.

Several studies have found that intermittent fasting can improve insulin sensitivity in both healthy individuals and those with prediabetes or type 2 diabetes. One study found that participants who followed an intermittent fasting diet had improved insulin sensitivity and lower fasting insulin levels compared to those who followed a traditional calorie-restricted diet.

Improved insulin sensitivity can also lead to other health benefits, such as reduced inflammation and a lower risk of developing chronic diseases such as heart disease and cancer. However, more research is needed to fully understand the mechanisms behind how intermittent fasting improves insulin sensitivity and its long-term effects on health.
