IGF1 is produced by the liver. When growth hormone reaches the liver it stimulates IGF1 to be produced.

Low protein diet = low IGF-1.

What influences levels of growth hormone (GH) and IGF-1 in the circulation include:

• Genetic make-up
• Time of day
• Age
• Sex
• Exercise status
• Stress levels
• Nutrition level
• Body mass index (BMI)
• Disease state
• Race
• Estrogen status and xenobiotic intake.

IGF-1 is a primary mediator of the effects of growth hormone (GH).

Growth hormone is made in the anterior pituitary gland.

Then it’s released into the blood stream, where it stimulates the liver to produce IGF-1.

IGF-1 stimulates systemic body growth, and has growth-promoting effects on almost every cell in the body.

Especially skeletal muscle, cartilage, bone, liver, kidney, nerves, skin, hematopoietic cell, and lungs.

In addition, IGF-1 can regulate cell growth and development, especially in nerve cells, as well as cellular DNA synthesis.

It increases the lifespan and is a fat burning hormone very similar to growth hormone.

Human Growth Hormone (HGH) is a very powerful hormone that changes the chemistry of the body so that it starts using fat for energy instead of just sugar.

It literally reduces the age of your metabolism.

It is the most anti-aging, fat burning, muscle building focus restoring and emotionally uplifting of all the hormones.

Studies have found that there is an inverse relationship between Body Mass Index (BMI) and HGH. For each increase in BMI of 1.5 kg/m2, there is a 50% decrease in the amount of HGH secreted per day.

What Else Does HGH Does For You:

• Increases calcium retention, and strengthens and increases the mineralization of bone
• Increases muscle mass. Don’t worry ladies, the muscle will grow in all the right places)
• Promotes lipolysis (breaking down fat for fuel)
• Increases protein synthesis. Your food goes to muscle, rather than body fat
• Stimulates the growth of all internal organs excluding the brain
• Promotes gluconeogenesis (creation of “new” blood sugar as opposed to simply releasing blood sugar) in the liver
• It stimulates the immune system.

It doesn’t take much to see how this affects your weight loss and fat loss. All the above allows your muscles to recover faster, grow stronger, and burn more fat.

Makes Your Metabolism Younger

Human growth hormone has been regarded as an anti-aging agent.

You can take identical twins who are obese and give only one of them this hormone and their fat will seem to “vanish” and their face will get more chiseled, the waist will get smaller and the muscles will grow in all the right places.

Growth Hormone Over Time

As a person grows older, the amount of HGH produced decreases. The graph below shows the natural decrease of HGH in your body over time.

I am not advocating a 70 year old should be able to look, feel and perform like an 18 year old. Not at all.

What I am saying is the levels of HGH in people today en masse are dramatically lower than normal. Both men and women and even teens are registering lower levels of HGH.

And in cases where there is too much growth hormone, it is synthetic growth hormone put into the body from eating animal meat injected with growth hormone, or from injected HGH supplementation.

The problem here is this is not “human” growth hormone. This is synthetic hormone not intended for humans. This can and does contribute to “abnormal” cell and organ growth in the body.

What Promotes HGH?

• Deep Sleep. Most HGH is secreted in deep sleep
• Resistance training
• Low levels of blood sugar (hypoglycemia)
• Dietary protein

What Stops HGH Secretion?

• Lack of sleep
• Lack of deep sleep
• Sleeping when exhausted
• Eating high glycemic index foods before sleep
• Chronic stress
• High cortisol levels(a hormone which is caused by stress)
• High blood sugar
• High Insulin levels
• Lack of sleep

I’m sure you want more detail on how to increase this hormone. Don’t worry, there are ways to naturally boost all these hormones!
