Why do people with insulin resistance lose more while fasting than others?

(Danielle ) #1

Hi there,
I heard recently on Fasting Talk podcast that people that are insulin resistant loose significantly more fat during fast than people that are not, despite having the same weight and body fat amount.

Does anyone know why?

Best regards,

I’d hazard a guess that it’s because their resting insulin is normally so much higher. Both an insulin sensitive person and an insulin resistant person will drive their insulin levels down during a fast, but in a IR person it’s got so much arther down to go that the effect is more pronounced for them.

Two types of insulin resistance IR:

  1. Physiologic (skeletal muscles) Good! Physiologic glucose sparing; see also: The Randle cycle, also known as the glucose fatty-acid cycle - Dr. Jack Kruse has a pretty good idea[1] about what’s happening with this!

  2. Hepatic (liver) Bad!

Thanks for your replies!

However, I still do not understand why insulin sensitive people would not start using fat and muscle to get energy during a fasting, just like insulin resistant.

I do not know whether I am insulin resistant or not, although as soon as I finished my exams and my dissertation I lost substantial weight during my extended fasts, in contrast to fasting during term time.

This is my second extended fast, and I loose about 0.5-1 kg per day. Is that good or bad? (I have about medium/10-12 uk in clothes size)

It might work something like this, just a hypothesis:

DHA (from marine life) regulates==>Somatostatin (SRIF) regulates==>HGH (somatotropin) and GH releasing hormone (GHRH)==>CT (cold thermal genesis and drinking 32 ounces water during…) Resets==>Leptin (is a hormone predominantly made by adipose cells that helps to regulate energy balance by inhibiting hunger)==>IGF-1 via levels decide whether or not dietary fattty acids or physiological fatty acids like white adipose tissue (WAT) is going to be burned for energy through brown adipose tissue (BAT) for thermal energy expenditure or whether or not WAT will be browned (“browning effect”)?==>IGF-1 (insulin growth like factor e.g. IF or EF) from liver rather than glucagon from pancreas) is released burning up triglycerides in WAT cells while CT is creating more BAT from WAT to increase thermal energy utilization expediture to warm the body when exposed to cold thermal conditions, more BAT improves glucose tolerance, and increases insulin sensitivity and acts as if it were GLUT 4 receptors in muscle tissue etc…

…or sumptin wike dat! Lol

…one more thing when you make WAT cells as cold as possible; it kills them, they self-destruct if they are not browned?

…viz. Hydrophilic Thermal Dynamics vs. Thermal Static?

It’s an interesting topic. It appears that at some level hyperinsulinemia supports fat levels. That explains why insulin resistant people can initially experience larger amounts of fat loss than those nonresistant. I myself experienced it, initially averaging well more than two lbs. per week. But, as adaption proceeded, that rate dropped and settled to between one and two lbs per week. This was without fasting, but because of lipolytic glucagon secretion.

It could be that high insulin levels caused insulin resistant people to become fat in the first place, and fasting reduces insulin levels drastically…

The way I understand this, it is not just fat cells that can become insulin resistant. Potentially all cells can become insulin resistant and different types of tissues and cells can have different levels of insulin resistance. So, as you lower your carb intake, you are reducing the amount of insulin that your body produces in response to your diet. Over time, your fasting insulin levels drop (this would be the “background” levels of insulin that are presumably always present in your blood and thus available to all the tissues in your body). But this fasting insulin level will only drop to the point of your MOST insulin resistant tissue because those cells still need that level of insulin to drive the glucose into them. So, that level of fasting insulin is what your body produces. This sets up the possibility that at some point in your “Keto journey”, one’s insulin levels ”catch up” to the insulin resistance of your fat cells and your insulin is no longer dropping low enough to trigger the fat cells into lipolysis.

Now, what if you introduce an extended fast? What if, over time (during this fast), your blood sugar drops and (presumably) your fasting insulin also drops even lower than before. Now it might reach a level low enough to trigger lipolysis and fat loss.

On the other hand, the rate of fat loss in an insulin SENSITIVE individual is not being held back by their fasting insulin levels, so fasting does not have a similar effect on their lipolysis.

The insulin “set point” may also drop naturally as the insulin resistant cells die off and are replaced by cells which are never exposed to high insulin levels present in carb burners.
