Insulin Resistance

Insulin resistance is a disorder with two parts: insulin isn't working as well as it used to in various body tissues, and at the same time, blood insulin levels are higher. Cells become 'deaf' to insulin's demands, requiring the pancreas to produce more insulin to achieve the same effect, leading to chronically elevated insulin.

Fast Insulin Resistance

This type of insulin resistance can be induced quickly (e.g., in six hours) by factors like stress, inflammation, or acutely high insulin levels. It also resolves quickly if these causative factors are removed, acting as a temporary protective mechanism for the body.

Slow Insulin Resistance

This develops over a longer period due to fat cells becoming excessively large, which then initiates a cascade of events leading to systemic insulin resistance. It takes longer to develop and also longer to reverse, as it involves fundamental changes in fat tissue function.

Personal Fat Threshold

This concept suggests that each individual body has a unique capacity to store fat in a healthy way. Once this threshold is exceeded, any further fat storage pressure leads to insulin resistance, with the threshold influenced by factors like ethnicity and sex, which determine fat cell number and distribution.

Ketosis

Ketosis is a metabolic state where the body primarily burns fat for fuel, producing ketones as a byproduct, especially when insulin levels are low for about 16 hours or more. Ketones serve as an alternative and highly efficient fuel source for the brain and can increase the metabolic rate of fat tissue.

Autophagy

Autophagy is a cellular process where cells clean themselves out by breaking down and recycling old or damaged components. It is thought to be a key contributor to longevity and is promoted by fasting or a ketogenic diet, as insulin acts as a powerful inhibitor of this process.

Metabolic Flexibility

This refers to the body's ability to efficiently switch between burning glucose and burning fat as its primary fuel source, depending on nutrient availability. A downside of prolonged ketosis can be a temporary reduction in metabolic flexibility, making it harder for the body to process glucose when consumed.

?
What is the common metabolic core linking many chronic diseases?

The common metabolic core linking many chronic diseases, from Alzheimer's to heart disease and type 2 diabetes, is insulin resistance. It's like branches growing from the same tree, with insulin resistance being the root problem.

?
How does insulin resistance contribute to conditions like infertility or Alzheimer's?

Insulin resistance can cause erectile dysfunction in men by making blood vessels resistant to insulin's signal to expand, and it's the most common cause of polycystic ovary syndrome (PCOS) in women. In the brain, it leads to 'insulin resistance of the brain' (Type 3 diabetes), where neurons struggle to get enough glucose, leading to cognitive decline.

?
Why do fat cells grow, and does the number of fat cells change over time?

Fat cells grow primarily due to the presence of insulin, which signals them to store energy, and the availability of calories to provide that energy. For most adults, the number of fat cells remains static after puberty; weight gain or loss is typically due to existing fat cells shrinking or expanding.

?
What is the evolutionary reason for insulin resistance?

Insulin resistance likely evolved as a physiological mechanism to help the body hold onto energy better during specific periods of growth, such as puberty and pregnancy, when high insulin levels are beneficial for tissue development and fat storage.

?
Does gestational diabetes impact the future health of the baby?

Yes, babies born to mothers with gestational diabetes are significantly more likely to gain weight, be chubbier, and develop type 2 diabetes later in life, as they are hardwired to a high insulin and glucose environment during development.

?
Why is Alzheimer's disease often referred to as 'Type 3 diabetes'?

Alzheimer's is often called 'Type 3 diabetes' because it's fundamentally insulin resistance of the brain. The affected brain regions cannot efficiently take in glucose, leading to an energy deficit that impairs cognitive function, especially in the absence of alternative fuels like ketones.

?
Can thin people have insulin resistance?

Yes, a person can be thin and still have insulin resistance, especially depending on their ethnicity or conditions like PCOS. It's not solely about body fat mass but rather the size and health of individual fat cells and the body's response to insulin.

?
How does smoking or vaping affect insulin resistance?

Smoking causes insulin resistance by eliciting a powerful inflammatory response due to the chemicals inhaled. Vaping is likely worse, as the hyperheated molecules can cause more damage to the airway, inflammation, and subsequent insulin resistance.

?
What are ketones, and how do they benefit the brain?

Ketones are a fuel source produced by the liver when the body burns a lot of fat, typically when insulin levels are low. They are an extraordinary fuel for the brain, improving cognitive function, memory, and even helping with neurological disorders like early-stage Alzheimer's, epilepsy, and migraines.

?
Are artificial sweeteners okay on a ketogenic diet?

Many artificial sweeteners like aspartame, monk fruit extract, stevia, allulose, and erythritol have no effect on insulin levels and are generally considered acceptable. However, some sugar alcohols (like maltitol) can have an insulin effect, and sucralose (found in 'zero' drinks) can cross the blood-brain barrier, which some prefer to avoid.

?
Is salt bad for us, and should we restrict it?

Salt has an undeserved bad reputation; while it can acutely raise blood pressure by causing water retention, its long-term effect on blood pressure is negligible. Insulin resistance is the main driver of high blood pressure, and restricting salt can actually make a person more insulin resistant, worsening the problem.

?
Why is exercise important for insulin levels, and what type is best?

Exercise is crucial for maintaining healthy insulin levels because muscle is a major consumer of glucose. Muscle-building work is particularly effective, minute for minute, at improving insulin sensitivity, as contracting muscles can take in glucose independent of insulin, directly lowering blood sugar.

?
What are the significant negative side effects of weight loss drugs like Ozempic?

Significant negative side effects of GLP-1 receptor agonists include a substantial loss of lean mass (muscle and bone), with up to 40% of weight lost coming from fat-free mass. This can lead to conditions like osteoporosis, especially in older individuals, and also increases the risk of suicidal thoughts and major depression.

1. Prioritize Muscle-Building Exercise

Engage in muscle-building activities, as they are more effective than aerobic exercise for improving insulin sensitivity and consuming glucose, which also predicts longevity.

2. Control Carbohydrate Intake

Focus on whole fruits and vegetables, and avoid processed carbohydrates from bags, boxes, and barcodes, as carbohydrates are not essential and significantly spike insulin.

3. Prioritize Protein Consumption

Emphasize animal-sourced protein, which provides all essential amino acids and, when combined with fat, promotes satiety and greater muscle growth.

4. Don’t Fear Dietary Fat

Include healthy fats with protein in your diet, as this combination is highly satiating, aids digestion, and is crucial for overall health and energy.

5. Practice Frequent Fasting

After adopting better eating habits (controlling carbs, prioritizing protein/fat), implement structured fasting periods to lower insulin, promote fat burning, and enhance cellular autophagy.

6. Increase Fat Intake on Ketogenic Diet

If following a ketogenic diet and aiming to preserve muscle mass, ensure sufficient fat intake, as muscle is metabolically expensive and needs adequate fuel to prevent breakdown.

7. Boost Salt and Hydration on Low-Carb Diets

When insulin levels drop due to carbohydrate restriction, the body eliminates more salt and water, making increased hydration and salt intake crucial to prevent dehydration and maintain performance.

8. Choose Insulin-Neutral Sweeteners

Opt for sweeteners like aspartame, erythritol, monk fruit extract, stevia, and allulose, as they have no impact on insulin levels, unlike some sugar alcohols or sucralose.

9. Avoid Sucralose

Steer clear of sucralose (found in many ‘zero’ drinks) because it can cross the blood-brain barrier, and its long-term effects there are unknown.

10. Do Not Restrict Dietary Salt

Contrary to popular belief, restricting salt has a negligible effect on blood pressure and can even cause insulin resistance; focus instead on reducing refined starches and sugars.

11. Measure Fasting Insulin Levels

Get your fasting insulin levels checked, as many people with insulin resistance have normal blood glucose but elevated insulin (above 10 microunits/mL in US or 40 picomoles/L in UK units).

12. Manage Stress Effectively

Actively work to reduce stress, as elevated stress hormones (cortisol, adrenaline) quickly cause insulin resistance by pushing blood glucose levels up.

13. Prioritize Quality Sleep

Ensure adequate sleep, as sleep deprivation is a potent way to increase cortisol and thus contribute to insulin resistance.

14. Moderate Caffeine Intake

Be mindful of caffeine consumption, as excessive amounts can strongly increase epinephrine, contributing to stress-induced insulin resistance.

15. Reduce Inflammation

Address sources of inflammation in the body, as inflammation directly increases insulin resistance.

16. Be Mindful of Air Quality

Recognize that inhaled particulates, such as diesel exhaust, can contribute to increased fat mass, enlarged fat cells, and insulin resistance.

17. Avoid Microplastics and Endocrine Disruptors

Limit exposure to microplastics and chemicals like BPA or DES found in plastics, soaps, and detergents, as they can directly promote fat cell growth and impact metabolic health.

18. Limit Sugar During Pregnancy

Pregnant women should be especially mindful of sugar intake, as excessive sugar can compound physiological insulin resistance into gestational diabetes, negatively impacting both mother and baby.

19. Avoid ‘Eat Less, Exercise More’ for Weight Loss

This traditional advice often leads to increased hunger and metabolic damage, making long-term weight loss unsustainable; instead, focus on lowering insulin to naturally reduce hunger.

20. Be Cautious with GLP-1 Weight Loss Drugs

Understand that GLP-1 receptor agonists can lead to significant loss of lean mass (muscle and bone), and may increase the risk of suicidal thoughts and depression.

21. Use GLP-1 Drugs Responsibly

If using GLP-1 drugs, combine them with proper education, prioritize protein and fat, lift weights to preserve lean mass, and aim for the lowest effective dose with a plan to eventually taper off.

22. Avoid Liposuction for Metabolic Health

Liposuction removes fat cells but does not improve metabolic health; it can lead to remaining fat cells growing larger and fat being stored in less healthy areas like the abdomen, worsening metabolic outcomes if lifestyle habits are not changed.

23. Avoid Vaping

Vaping is likely worse than smoking in terms of inflammatory effects, damage to the airway, and contribution to insulin resistance.

24. Consume Animal-Sourced Omega-3s

Ensure adequate intake of essential omega-3 fats, particularly EPA and DHA, which are primarily found in animal-sourced foods and are crucial for brain health.

25. Vegans Must Supplement Essential Nutrients

Vegans should be educated on potential nutrient deficiencies (e.g., essential omega-3s) and supplement accordingly to support brain health and overall well-being.

26. Monitor Triglyceride Levels

Pay attention to triglyceride levels, as they are a more predictive marker for heart attack risk than cholesterol levels.

Insulin resistance is the core for most chronic diseases that are killing us.

Four Pillars for Controlling Insulin Resistance

Dr. Benjamin Bikman
  1. Control carbohydrates: Focus on whole fruits and vegetables (eat, don't drink), and avoid carbohydrates from processed foods (bags, boxes with barcodes).
  2. Prioritize protein: Consume animal-sourced protein, which provides all essential amino acids.
  3. Don't fear fat: Eat fat in combination with protein, as it is satiating and helps with digestion and muscle growth.
  4. Frequently fast: Once the first three pillars are established and the body adapts to burning its own fat, adopt a structured fasting strategy (e.g., intermittent fasting, alternate-day fasting) to further lower insulin.
