Fasting insulin

Fasting insulin – is the level of insulin in the blood measured after overnight fasting, usually after 8-12 hours without food.

This indicator is an important marker of the body’s metabolic state and can help in diagnosing various diseases, including diabetes and insulin resistance.

Importance of Fasting Insulin

Insulin – is a hormone produced by the pancreas that plays a key role in regulating blood sugar levels. It helps the body’s cells absorb glucose, which is especially important after eating. However, when fasting insulin levels are elevated, it may indicate metabolic issues.

Normal Values

The normal level of fasting insulin typically ranges from 2 to 25 µU/mL.

Values above this range may indicate the presence of insulin resistance or other metabolic disorders.

Causes of Elevated Fasting Insulin Levels:

• Insulin resistance
• Type 2 diabetes
• Obesity
• Hormonal disorders
• Certain liver diseases

Impact of the Keto Diet on Insulin Levels

The keto diet, based on high fat intake and low carbohydrate intake, can significantly affect fasting insulin levels.

As the body begins to use fats as the primary energy source instead of carbohydrates on the keto diet, blood glucose levels decrease, which in turn leads to a reduction in insulin levels.

A decrease in fasting insulin levels can have several positive effects:

• Improved insulin sensitivity
• Reduced risk of developing type 2 diabetes
• Weight loss
• Improved overall health

Conclusion

Measuring fasting insulin levels is an important tool for assessing health and metabolism. Understanding this indicator, as well as the impact of various diets such as the keto diet, can help in weight management and disease prevention.

If you are concerned about your insulin levels, it is recommended to consult a doctor for further information and advice.
