Fasting Insulin

Fasting insulin is a critical biomarker that provides insight into your body’s metabolic health. Insulin, a hormone produced by the pancreas, is vital in regulating blood sugar levels. Elevated fasting insulin levels can indicate insulin resistance, a condition that has been linked to a range of chronic diseases, including type 2 diabetes, obesity, and cardiovascular issues.  

Monitoring fasting insulin levels is essential for understanding how your body processes glucose. Ideally, lower fasting insulin levels reflect a healthy metabolism and efficient glucose utilisation. High insulin levels can lead to increased fat storage and difficulty losing weight, hindering overall health and longevity.  

Dietary choices play a significant role in optimising fasting insulin levels. Adopting a diet low in refined carbohydrates and sugars can help stabilise blood sugar levels and reduce insulin spikes. Incorporating whole-natural foods, healthy fats, and fibre-rich vegetables can improve insulin sensitivity and promote better metabolic health.  

Regular physical activity is also crucial. Exercise enhances insulin sensitivity especially in skeletal muscles, allowing your body to utilise glucose more effectively. Strength training, in particular, has been shown to improve insulin response and support a healthy weight.  

Lastly, managing stress and ensuring adequate sleep are vital components. Chronic stress and poor sleep can disrupt hormonal balance, increasing insulin resistance. By focusing on these factors, you can maintain healthy fasting insulin levels, supporting metabolic health and longevity. Understanding your body’s insulin response is a decisive step toward achieving optimal health and a vibrant life.
