Physiology 101

Insulin is the gatekeeper for glucose: it allows glucose to get inside the cells where it can be utilized for energy or for storage. When glucose gets used, your cells produce ATP (your trunk's energy currency). When glucose gets stored, it gets stored as triglycerides (fat).

Insulin is necessary, of course. Without it, as in Type 1 Diabetes, glucose tin't become into the cells. Without adequate replacement, this leads to blood vessel damage, cardiovascular disease, kidney disease, etc. Too much insulin, on the other hand, means insulin resistance: your cells become desensitized to its signal. This as well means too much glucose in the bloodstream and not plenty in the cells, rendering y'all susceptible to the same complications. Somewhen this can lead to Blazon two Diabetes.

Opposite insulin is Growth Hormone (GH). Growth Hormone allows kids to reach their full elevation, and it likewise enables muscle growth and repair. Information technology primarily tells the liver to produce its messenger, Insulin-Similar Growth Gene-1 (IGF-1)—so called because structurally, it is quite similar to insulin. It can even bind insulin receptors (though much less strongly than insulin, and it appears to take an opposite result when information technology does then.)

The job of IGF-one is to stimulate tissue growth (muscles, bones, etc). It as well helps to proceed inflammation in check. Low levels of IGF-one is associated with loftier levels of inflammatory cytokines, which can perpetuate autoimmunity (and inflammation of all kinds. This may be function of the reason why eating too much sugar leads to inflammation!) Low GH and IGF-1 are also found in fibromyalgia, implying that hurting may at to the lowest degree in role occur every bit a result of inability of the muscles to repair themselves.

When insulin is high, GH and IGF-one are both low, and vice versa. They're similar a teeter totter.

How to Lower Growth Hormone and IGF-i (and Enhance Insulin)

For most of us, this is the opposite of what nosotros want to exercise. Factors that raise insulin include:

  • High stress. Acute stress, and early phase adrenal fatigue both mean high cortisol. Cortisol mobilizes glucose from the liver. Glucose triggers insulin, and lowers Growth Hormone. And then when stress is high, information technology'south unlikely you lot'll exist able to bulk up at the gym like you're used to.
  • High carbohydrate intake. Eating lots of sugar spikes your glucose, which spikes your insulin. This, besides, lowers Growth Hormone. (This means, too, that poor glucose regulation and insulin resistance in kids can adversely bear upon growth.)
  • Loftier Growth Hormone itself. The torso's fragile hormone balance relies on feedback mechanisms: as well much of whatsoever one hormone leads to feedback inhibition of itself. Information technology'south like a prophylactic band snapping back. Pretty smart, actually.

The Upshot: How to Lower Insulin (and Raise Growth Hormone and IGF-1)

If you're looking to assistance your child achieve full stature, build muscle mass, or repair muscle damage, Growth Hormone and IGF-1 are your friends. To lower insulin (and increase Growth Hormone), you can:

  • Lower your blood sugar.In betwixt meals, when claret sugar naturally falls, Growth Hormone likewise naturally rises. (This is why Growth Hormone rises during sleep; run across bullet point 4.) To mimic this procedure, both intermittent fasting and ketosis work well, but they can be pretty intense. If y'all typically eat a Standard American Nutrition, even but eating like this volition go a long manner. (And if you lot're looking to optimize your kid's growth, I'd certainly go for the Basic Healthy Eating plan.)
  • Consume plenty of protein. Poly peptide not merely stabilizes glucose levels, it also serves equally the edifice blocks for cellular growth (since we're made of protein ourselves). Furthermore, protein directly raises IGF-1 levels.
  • Become enough of sleep.   Equally mentioned higher up, the bulk of Growth Hormone is released in the deeper stages of slumber. (This is part of the reason why fibromyalgia is often considered primarily a sleep disorder: lack of sleep means lack of GH, which means lack of muscle repair.) Growth Hormone declines as forenoon approaches, and cortisol rises, spiking glucose and therefore insulin.
  • Exercise. Particularly resistance exercise is great for muscle building. It also therefore lowers insulin and raises Growth Hormone.
  • Become your micronutrient levels checked. Zinc, magnesium, and selenium levels are significantly correlated with IGF-i activity. If levels of whatsoever of those nutrients are low, supplementation will assistance with raising Growth Hormone and IGF-ane levels.
