Insulin: Major Causes Of Resistance And Why

Obesity

A diet high in refined carbohydrates, processed foods, and sugar may lead to obesity, which is widely associated with an increased risk of insulin resistance. According to a 2012 study, prolonged exposure to a high amount of fatty acids may lead to insulin resistance. Saturated fatty acids, such as stearic and palmitic acids, were found to the most potent cause of insulin resistance. The study went on to state fatty acids impair insulin actions by creating oxidative stress, modulating gene transcription, and causing mitochondrial dysfunction and inflammation.

Refined Carbohydrates

Research shows processed or refined carbohydrates including sugary cereals, pasta, white rice, bread, and artificial sweeteners have been linked to weight gain, increased fatty acids in the liver, overeating and increased appetite, metabolic syndrome, systemic inflammation, high blood sugar, insulin resistance, and diabetes. A 2014 study found a higher consumption of refined grains such as white rice increases the risk of type two diabetes. The study stated a high consumption of rice and noodles might contribute to hyperglycemia due to greater insulin resistance. Healthy carbohydrates to focus on instead are fruits and vegetables.
