Debunking Diabetes Myths: Insulin Resistance and Lifestyle Factors
Diabetes, a common chronic condition, often carries misconceptions. One prevalent belief is that consuming too much sugar leads directly to type 2 diabetes. However, according to nutritionist Charmaine Ha Dominguez, this is a misconception. “I frequently hear this from people newly diagnosed with type 2 diabetes, and they are bewildered. High sugar levels in the blood are a symptom, not the primary cause,” Dominguez explained.
Understanding Insulin Resistance
The actual culprit behind type 2 diabetes is insulin resistance. Dominguez elaborates, “Insulin resistance occurs when fatty acids build up in the liver and muscle cells, obstructing insulin receptors. This prevents insulin from effectively ushering glucose from the blood into the cells, resulting in high blood sugar levels.”
Lifestyle Factors Contributing to Insulin Resistance
“Three main factors contribute to insulin resistance: a sedentary lifestyle, a high-fat diet, and excess calorie intake,” Dominguez adds. This emphasizes that while sugar does play a role, other dietary and lifestyle choices significantly impact diabetes risk.
Diet and Insulin Resistance
Dr. Manisha Arora, director of internal medicine at CK Birla Hospital, Delhi, further details the complexities. “Individuals can avoid sugars but still be at risk for diabetes if they consume high-fat foods and are overweight,” she stated. “Obesity, particularly visceral fat accumulation, which is more common among Asian Indians, can impair insulin secretion and lead to increased insulin resistance.”

The Impact of Obesity and Weight Loss
Arora also notes that weight loss can release stored insulin from fat cells back into circulation, potentially improving diabetes management. “Addressing excess body fat can lead to better insulin sensitivity and metabolic health,” she emphasizes.
Other Lifestyle Considerations
Stress and lack of sleep further complicate diabetes risk. Dr. Jinendra Jain, a consultant physician at Wockhardt Hospital, Mira Road, states, “Stress and inadequate sleep disrupt hormonal balance and metabolic functioning, leading to abnormal blood sugar levels.” He adds that a sedentary lifestyle, advanced age, and certain medications, such as steroids and some antidepressants, can also contribute to increased diabetes risk, irrespective of sugar intake.
Preventive Measures and Lifestyle Changes
To manage and prevent type 2 diabetes, focus on a balanced diet rich in fresh fruits, vegetables, whole grains, pulses, lentils, and seeds. Dr. Jain advises avoiding junk, processed, oily, canned, sugary, and refined foods. Regular exercise for at least 45 minutes a day, along with yoga and meditation to reduce stress, and ensuring eight hours of quality sleep each night, are crucial for maintaining healthy blood sugar levels.
Conclusion
While it’s tempting to blame sugar for type 2 diabetes, the reality is more complex. Insulin resistance, influenced by diet, exercise, and lifestyle choices, is the primary driver of the condition. Understanding these factors can lead to better management of diabetes and improved overall health.
