Insulin Resistance Insulin Sensitivity

Insulin Resistance Insulin Sensitivity

As a Type-1 Diabetic and due to the manner in which I learned to manage it, Insulin Resistance became a passionate topic for me as it is a fundamental element of metabolic control. I learned that the lower the insulin resistance, the less insulin I had to inject and the better I felt. However, it wasn’t until two and a half decades later that I discovered that there was actually a technical term for this metabolic relationship; Insulin Resistance.

What is insulin?
Insulin is a hormone that enables the metabolism (“burn rate”) of glucose. Insulin is produced by a portion of the pancreas and is secreted into the blood stream. It is produced in direct response to the level of glucose in the blood stream to regulate a near constant blood-glucose level. As glucose rises, more insulin is produced to burn the glucose into energy, as blood-glucose decreases, less insulin is produced.

What is Glucose?
Glucose is the simple sugar that is biology’s fuel.

What is insulin resistance?
Insulin resistance is an extremely common condition affecting almost every American, however it is rarely diagnosed. Most commonly, when it is diagnosed it is labeled under various other terms, including chronic fatigue syndrome. It is important to understand that insulin resistance is by degree and that everyone has it and that it is continuously variable and that it is lifestyle related and that it is reversible and that it is not genetic or something you catch or something you get and are stuck with. It is something to overcome.
There are two primary lifestyle elements that influence insulin resistance: food and exercise. Insulin resistance is variable in step with each of these, however, it is possible to become insulin sensitive (opposite of insulin resistant) with food alone. The object is to become insulin sensitive. The more insulin sensitive you are, the more energetic, healthy and vibrant you are.

How does it work?
Insulin resistance is when insulin is impeded from enabling metabolism of glucose. Insulin resistance could also be called energy resistance. Insulin resistance causes a delay between insulin production and cell metabolism. As blood-glucose rises, the pancreas increases insulin production in step. With insulin resistance, however, glucose is metabolized too slowly, allowing blood-glucose levels to continue to rise, prompting the pancreas to pump out even more insulin. Eventually, metabolism starts to catch up, but now the insulin level is too high, burning glucose too fast resulting in blood-glucose falling too low. This is called Hypoglycemia. Without insulin resistance; blood-glucose, insulin production and metabolism all respond in sync. With an in-sync metabolism, every part of your body functions at peak efficiency. That is where you feel the best; where you are never “tired” and where you crave physical effort just because it feels so good.

Foods that cause and elevate insulin resistance:

  • Oil – any oil, any amount. There is no such thing as “a little bit”.
  • Animal products – any, including meat, egg, cheese, milk, butter, yogurt, etc…
  • Fat – any fat.
  • Nuts
  • Nut Butters
  • Avocado
  • Coconut
  • Seeds

 

Foods that elevate insulin sensitivity:
Important – there are no foods that counteract or reduce the effect of foods that increase insulin resistance. Foods that increase insulin sensitivity only do so in the >absence of foods that increase insulin resistance.

  • Vegetables and Leafy greens, especially Kale, spinach, etc.
  • Beans, Legumes
  • Whole fresh Beets, including steamed, but not pickled, etc.
  • Root vegetables; Carrots, Parsnip, potatoes, beets, etc.
  • Whole grains; Brown Rice, Whole wheat, Whole kernel corn, etc.
  • Squash
  • Fresh fruit

 

Foods that may spike blood-sugar if insulin resistance is high: 

Note: sugar, of any type, does not cause or contribute to insulin resistance, however, if insulin resistance is already high, metabolizing sugar will be slow, resulting in blood sugar spikes.

  • Any processed food; anything made with flour, anything out of a box or bag. Note: practically all processed foods are processed with oil. Products with “low fat” on the label are not required to actually be low fat.
  • Sugary drinks
  • Anything with processed sugar
  • White potato (not a problem when insulin sensitive)
  • White rice (not a problem when insulin sensitive)
  • Dried fruit (not a problem when insulin sensitive)

 

Things other than food that reduces insulin resistance:
• Aerobic exercise

Management Notes:

The object is to keep insulin resistance as low and insulin sensitivity has high as possible. The lower the resistance the more efficient your metabolism, the more energy you have, the healthier you are and the better you feel.

Keep total fat calories of every food item below 10%. Example: a 100 calorie food item should have less than 10 calories of fat. Fats are essential nutrients, however, no worries about too little fat. All fats are extremely concentrated. Except for starving to death, you simply cannot be fat deficient.

Keep total protein calories of any food item below 10%. Example: a 100 calorie food item should have less than 10 calories of protein. Proteins are essential nutrients, however just like fat, no worries about getting too little. (Note: the wide spread belief that protein is such a vital nutrient and that “the more the better” began several decades ago from a beef and dairy industry advertising campaign.) Click here for more information on protein.

Animal sourced protein causes insulin resistance by a different mechanism from fat. Instead of directly inhibiting insulin, it inhibits your efficiency by damaging the endothelium cell lining of the blood vessels, reducing nutrient and oxygen transfer. It also disrupts the immune system resulting in inflammation and autoimmune conditions among a long list of other issues. More information from Dr. Caldwell Esselstyn .

Initially, all this sounds very limiting – having to give up many or most of your beloved foods - but it is not. Not even a little bit. Here is what I learned about giving up damaging foods.

For more information about the popular medical analysis of insulin resistance, please see my blog post: Glycemic Index and Attention Span.

Maximizing insulin sensitivity by keeping total fat, of everything eaten below 10% and elimination of animal sourced products will give you a lifetime of liberating energy and feel-good. Among countless others, this is what happened to Ruth Heidrich. Her image, below, illustrates what insulin sensitivity feels like at 80 years of age:

  • Fantastic post Ken! Wow. I am so grateful for such a good resource to share with others. That is what I am doing now. Sharing this on my social network pages and in my social network groups. Keep up the good work!

  • Thanks Ken for this really informative post. My 23 year old daughter has just been diagnosed as insulin resistant and hypoglycemic. This diagnosis comes 2 1/2 years after having having successful thyroid cancer surgery. We have begun following your advice listed in the post. It is incredibly hard for her to give up so much, but she does know that the consequence for not curing the insulin resistance is potentially becoming diabetic. So she is grudgingly following the new way of eating (NOT a diet! a lifestyle change!) One question, can you explain the concept of not eating any flour, even whole grain flour products, such as whole wheat pasta and corn tortillas? If these items could be included a couple of times a week it would be such a plus for her. Thanks again for your wonderful information.

  • Hi Nancy,
    Thank you for the kind words. I really look forward to your daughter's improved health!
    About your question: "One question, can you explain the concept of not eating any flour, even whole grain flour products, such as whole wheat pasta and corn tortillas? If these items could be included a couple of times a week it would be such a plus for her."
    Short answer: It exaggerates the hypoglycemia.
    Long answer: The process of grinding grains into a flour concentrates the calories. This makes digestion faster, thus increasing blood-sugar faster than the insulin response - due to the insulin resistance. In response to the delay, the pancreas pumps out more insulin. Then, once the insulin response catches up, there is too much insulin resulting in hypoglycemia.
    She will be able to tell when she can tolerate these foods. When the hypoglycemia has stopped, she can test with a meal. If no hypoglycemia, then she is well on her way to recovery. However, even for everyone, processed foods should not be routine.
    Here's to health!

    Nancy,
    Even though Ken provided you a very good response I thought that perhaps the following article might help you and your daughter to really understand what food processing is and is not. Some of it is intuitive and the rest may appear like it should have been intuitive. :-) Please read the following article and let me know if it makes sense to you:

    Thanks, Sean

  • Hi Nancy,

    You mentioned that your daughter is suffering from a loss of favorite foods: “…It is incredibly hard for her to give up so much, but she does know that the consequence for not curing the insulin resistance is potentially becoming diabetic. So she is grudgingly following the new way of eating…”

    I think it is helpful to realize that the feeling of loss; of giving up beloved foods, is losing the comfort of familiarity. It is also helpful to realize that taste is a learned sense. The taste of foods that one grows up with is what tastes good. With that taste firmly embedded in years of one’s life, other foods are foreign and tasteless. The good news is that (even though this seems unimaginable), given enough time after trading all of the animal sourced foods for plant foods, the cherished tastes of “bad” foods shift to the “good” foods. Not only does one’s taste shift, the enjoyment of the good foods so outweighs the old “bad” food that it is becomes face making yuck. This increase in taste and enjoyment of the “good” food over the “bad” food is enhanced even further due to the association of increased health, energy and vitality.

    The key is total commitment for however long it takes to reset your system. It feels like a monumental mountain to climb, but once over the peak, you will have new, even more beloved foods. The feeling of loss completely gone replaced by a feeling of gain. See my blog on that subject here: https://www.starch-smart.com/blog/entry/sacrifice

    To help get over that mountain; keep yourself full – do not go hungry. Eat throughout the day, unlimited. In fact, one should eat at least two full pounds of unprocessed veggies every day. The best veggie snacks are raw. A few of my favorites are broccoli, carrots, snap-peas, etc. That sounds grueling, but eventually it won’t be so bad, then you grow to like it, then crave it, and ultimately cherish it. Actually, for many, the transition is grueling because eating any animal source food destroys our natural gut flora and it takes a few weeks to months to restore it. The transition is somewhat like withdrawal symptoms, but it is very worth it. Few people have ever experienced how good it feels to have a digestive system with a fully functioning gut flora!
