What is Insulin Resistance? [1][2][3][4][edit | edit source]

Insulin Resistance (IR) is a condition in which the cells of the body become resistant to the effects of insulin. Thus, a person is said to have impaired glucose tolerance / pre-diabetes. IR results in higher levels of insulin being required to maintain normal blood glucose levels. Eventually, the pancreas may be unable to keep up with insulin demand leading to long term health issues.

  • 1 in 4 adults in Australia may at some time in their life have impaired glucose tolerance
  • Being diagnosed with impaired glucose tolerance does not necessarily mean you will develop diabetes, but it makes you 10-20 times more likely than a normal person
  • It is estimated that up to 1.8 million Australians are living with diabetes / impaired glucose tolerance

Who is at Risk of Developing Insulin Resistance? Patients who - [1][2][5][6][edit | edit source]

  • Are overweight / obese
  • Are Aboriginal or Torres Strait Islanders
  • Are pregnant
  • Have a high fat diet
  • Have a family history of type 2 diabetes, hypertension or heart disease
  • Have a sedentary lifestyle

Classic Side Effects [2][3][4][7][edit | edit source]

A patient with IR may remain asymptomatic (no signs of symptoms) for an extended period of time, classic symptoms are often linked to:

Acute Side Effects
Hyperglycaemia Symptoms Hyperinsulinemia Symptoms
Slow Healing Brain Fogginess (inability to concentrate)
Frequent Thirst Blurred Vision
Frequent Urination Fatigue
Chronic Side Effects
Macro Vascular Issues Micro Vascular Issues Hyperinsulinemia Issues
Stroke Retinopathy (Blindness) Type 2 Diabetes
Heart Disease Nephropathy (Kidney Disease) Hypertension
Neuropathy (Nervous Tissue Damage) Bad Cholesterol
Weight Gain / Central Obesity
Polycystic Ovary Disease

Recommendations for Insulin Resistance Management [8][9][10][11][edit | edit source]

Always seek professional health guidance before commencing a training regime

Remember adherance to any form of physical activity is the most crucial step in reversing Insulin Resistance

Aerobic Exercise Recommendations
Guidelines Benefits
At least 30 minutes / moderate intensity on most days of the week Improves insulin sensitivity (Reverses IR)
Or at least 20 minutes / vigorous intensity three times per week Improves quality of life
Influencing lifestyle choices can also contribute to daily aerobic activity Controls blood glucose, insulin and blood pressure levels
• Transport - substitute driving with walking or cycling to work Reduces the risk of obesity, death and illness
• Recreation - substitute indoor activities for outdoor activities Reduces the risk of chronic IR issues
• Occupation - substitute the elevator for the stairs to the office • Macro Vascular issues
• Home - subtitute take away for a home cooked meal • Micro Vascular issues
• Hyperinsulinemia issues
Examples of Aerobic Activity that Meets the Guidelines
Low Intensity Moderate Intensity High / Vigorous Intensity
Does not cause a noticeable change in breathing rate Able to maintain a conversation uninterrupted Unable to maintain a conversation uniterrupted
• Washing • Walking • Jogging
• Cooking • Swimming • Aerobics
• Cleaning in the Home • Social Sports • Competitive Sports
