Unravelling the Mystery of Insulin Resistance: The Modern Diet and the Rise of Diabetes


Insulin resistance is a concerning health issue that has become increasingly prevalent in recent decades, coinciding with the rise in processed foods and sedentary lifestyles. In this article, we’ll explore why we become insulin resistant and the role that our modern diet and lifestyle play in the growing epidemic of diabetes.

Understanding Insulin Resistance

Insulin is a hormone produced by the pancreas, and its primary role is to regulate blood sugar (glucose) levels. It does so by facilitating the uptake of glucose into cells, where it can be used for energy. Insulin resistance occurs when cells in the body become less responsive to the effects of insulin, which means they don’t efficiently take up glucose. To compensate for this, the pancreas produces more insulin, resulting in elevated levels of this hormone in the bloodstream.

The Modern Diet and Insulin Resistance

1. Excessive Sugar and Refined Carbohydrates: One of the leading factors in the development of insulin resistance is the excessive consumption of sugar and refined carbohydrates. Foods and beverages high in added sugars lead to rapid spikes in blood sugar, which, over time, can impair insulin sensitivity. The modern diet, filled with sugary snacks, sugary drinks, and processed foods, significantly contributes to this issue.

2. Unhealthy Fats: A diet high in unhealthy fats, particularly trans fats, and saturated fats, can also contribute to insulin resistance. These fats can lead to inflammation in the body, making cells less responsive to insulin.

3. Lack of Fiber: Highly processed foods often lack the fibre found in whole, unprocessed foods. Fiber plays a vital role in regulating blood sugar and insulin levels. The absence of fibre in the diet can exacerbate insulin resistance.

4. Excessive Caloric Intake: The abundance of calorie-dense, processed foods can lead to overeating and, subsequently, obesity. Obesity is strongly associated with insulin resistance, as excess fat can cause inflammation and disrupt the body’s ability to regulate blood sugar.

The Rise of Diabetes

The prevalence of insulin resistance and its subsequent link to type 2 diabetes has seen a sharp increase in recent decades. Several factors contribute to this rise:

1. Sedentary Lifestyle: Modern life often involves prolonged periods of sitting and minimal physical activity. Physical inactivity can lead to obesity and exacerbate insulin resistance.

2. Stress: Chronic stress can lead to hormonal imbalances, including elevated levels of cortisol, which can affect insulin sensitivity.

3. Environmental Factors: Environmental toxins, such as pollutants and endocrine-disrupting chemicals, have been associated with an increased risk of diabetes and insulin resistance.

4. Genetics: Some individuals may be genetically predisposed to insulin resistance, making them more vulnerable to developing diabetes.


Insulin resistance is a complex condition influenced by a variety of factors, with our modern diet and lifestyle playing a significant role. The consumption of processed foods, excessive sugar, and unhealthy fats, coupled with reduced physical activity, has created an environment ripe for insulin resistance and the subsequent rise in diabetes. To combat this growing health concern, it is essential to prioritize a balanced diet, regular physical activity, and stress management. Additionally, raising awareness and advocating for healthier food choices and policies can help mitigate the impact of our modern diet on our health.
