The Dreaded Seven . . . (Seven Detrimental Things Caused by High Insulin Loads)

85% of the people that walk through my office doors have some degree of insulin resistance.

What is “insulin resistance?”  It is an over production of insulin in response to ANY form of carbohydrate intake (yes, even the “good carbs” cause an insulin over-response in a person with insulin resistance.)

How do I know this? Because I routinely check insulin levels (I check them every three months) and the down stream markers of insulin on a large number of the patients that I see.  I have been fascinated by the fact that a diet high in both sugar and fat [like the Standard American Diet, (SAD) diet]  turn on the genetics leading to insulin resistance.  Starch and sugar load the genetic gun.

Insulin acts like a key at the glucose doorway of every cell in your body.  In many people, the insulin signal is blocked by hormones produced in the fat cell and the the insulin, acting like a “dull or worn out key” – can’t open the glucose doorway as efficiently.

So, the body panics, and releases extra insulin in response to the same load of carbohydrate or glucose.  People with insulin resistance will produce between 2-20 times the normal amount of insulin in response to a simple carbohydrate load.  Recent studies(1, 2) reveal high cholesterol and diets high in both fat and carbohydrate cause insulin resistance to progress or worsen.

So, instead of producing enough insulin to accommodate the one slice of bread or the one apple that you might eat, the insulin resistant person produces enough insulin for an entire loaf of bread or an entire bushel of apples.  This excess insulin then stimulates one or all of the following:

  1. Weight Gain – Insulin directly stimulates weight gain by activating lipoprotein lipase to take up triglycerides into the fat cells.  This causes direct storage of fat and increases your waistline. (3)  weight tape measure
  2. Elevated Triglycerides – Insulin directly stimulates production of free fatty acids and triglycerides through hepatic gluconeogenesis and is even more notably amplified by the broken signaling mechanism of the FOX-01 phosphorylation mechanism in patients with insulin resistance.

  3. Increased number of Small Dense LDL (sdLDL) particles – Low density lipoprotein (LDL, or “bad cholesterol”) is actually comprised of various sized lipoproteins including small, medium and large.  As triglycerides increase, the small dense LDL particle numbers increase.  Research points to the fact that it is the small dense particle that is highly atherogenic (leading to the formation of vascular plaques within the arteries). (5, 8)
  4. Elevated Uric Acid – Leptin resistance and insulin resistance syndromes are often found together and are suspected to have significant influence on each other.  High insulin loads lead to “sick adipose cells” causing leptin resistance.  This has a dramatic effect on hepatic fructose metabolism increasing the production of uric acid.  Excess insulin suppresses urinary excretion of uric acid and dramatically increases serum content of uric acid and the risk of kidney stones and gout. (6, 7)gout-pain
  5. Increased Inflammation – Increased levels of circulating insulin have a direct correlation on raising many of the inflammatory markers and hormones including TNF-alpha and IL-6 in the body (9).  Any disease process that is caused by chronic inflammation can be amplified by increased circulating levels of insulin including asthma, acne, eczema, psoriasis, arthritis, inflammatory bowel and celiac disease, etc.
  6. Elevated Blood Pressure – Increased uric acid production from insulin resistance as noted above directly suppresses production of nitric oxide within the vasculature and increases blood pressure (7). This completes the triad of metabolic syndrome (elevated triglycerides & cholesterol, weight gain, and elevated blood pressure) found in patients with insulin resistance.Blood-pressure
  7. Water Retention – We have known for many years that insulin affects the way the kidney uses sodium in the distal nephron.  Insulin has a direct effect on sodium retention in the kidney.  As insulin levels rise, the kidney retains increased levels of sodium (10).  Water follows sodium and thereby causes fluid retention.  This is the reason that many of my insulin resistant patients who have struggled with leg swelling and edema suddenly improve when they correct their diet and their high circulating insulin levels fall.  It is also the reason that many of my patients show up in my office after the holidays with swollen legs and amplified swelling in their varicose veins after cheating on their ketogenic diets.

If you are plagued by any or all of these, my first suggestion is to see your doctor and get screened for insulin resistance.  I treat patients with these every day and have reversed these effects in thousands of patients with the correct diet and/or medications.  Having seen these signs and patterns over the last 20 years of medical practice, I am still astonished every day by the dramatic effect our diet plays on the hormonal changes within the body. Remember that the food you eat is actually the most powerful form of medicine . . . and the slowest form of pernicious poison.

A ketogenic or carnivorous diet is your first step.
