They say that low carb diets increase IGF-1, hence [B]insulin blocks the production[/B].
[B]Intermittent fasting[/B] supposably causes a further[B] increase in HGH [/B]
Now, lets say I (a 16 year old teen on the primal diet) wants to add a few inches to his height (5'8")
You guys think this can effect my potential height outcome?
Being that I:
•[B]Eat a lot[/B] of meat, poultry, eggs, vegetables, high-fat dairy, nuts, and [B]moderate fruit[/B]
•Get adequate amounts of [B]sleep [/B]
•lift weights, runs, hikes etc.
•[B]Am 145 lbs 10% bf [/B]
PS, Think insulin sensitivity, ketosis, and hormones
Studies would be nice, not necessary. Just looking for your opinions ;)
Trying to hack the adolescent cycles is pretty unexplored terrain. There are probably lots of feedback loops and counter-regulations we don't know about. My hunch is that ample protein, calories, and micros are the main factors (within your genome ofc).
Sure environmental factors can and will effect your height. But, beyond eating an adequate diet congruent with being a human animal it's really not been studied in depth. Sure we can postulate a theory based on what we know, but like picklepete points out we will likely overlook/just not know all the pathways to give a result better than "just eat primal and do congruent exercise".
Look at it this way. I bet if you took all the shit we think we know and developed the ultimate adolescent height hack. Then we did a randomized control trial with "The Ultimate Height Hack" vs "The Primal Plan" vs "Control (i.e. SAD)". What do you think the results would be? I venture that you MIGHT get a statistically significant difference between the control and the other two groups, but there would be no statistical difference between "The Ultimate Height Hack" and "The Primal Plan". Just my guess.

I think this paragraph is quite interesting:
"Staffan Lindeberg thinks that excessive serum levels of IGF-1 from diet-induced hyperinsulinemia are causing unhealthy amounts of growth, which manifest as higher rates of cancer and, yes, height, in Western populations. Simply put, Lindeberg agrees that a population’s height is an indicator of health, but only to a point, after which it indicates excessive and potentially problematic levels of IGF-1. There’s probably something to this; female centenarians are more likely to have an IGF-1 receptor mutation that results in elevated serum levels of IGF-1 while reducing IGF-1 receptor activity. In other words, the body was producing more IGF-1 to make up for the lack of receptor activity. This same receptor mutation has been linked to longevity in multiple animal models resulting in higher serum IGF-1 and lower IGF-1 receptor activity – just like in the human centenarians. In male and female offspring of the centenarians, however, only females showed elevated serum levels. Male offspring had similar IGF-1 levels to control males (those with no familial history of longevity). Female offspring were also 2.5 cm shorter than control females; male offspring were of similar height to control males. Perhaps short stature is more beneficial to women?"
Take up contortionism. They say that a contortionist is 3" taller than if they had not done that.
Human growth hormone is pretty easy to get.
The fasting will get you some. But proper exercise will get you much more.
One study looking at male sprinters found that a 30 second all out sprint boosted human growth hormone levels by more than 500 percent over resting baseline.
Another study looking at cyclists saw similar results with those on the upper end spiking 600 percent over baseline.
So short and sweet routines, done consistently will get you the HGH you're looking for.
As long as the intensity is high enough.

Very interesting info! There are very little studies done on growth patterns related to diet and exercise, but I'm a strong believer that being healthy, eating what our bodies are designed eat, and activity levels all are factors in reaching height potential. Some of my friends, 15-16 years old, have grown freakishly tall and developed way earlier than me
(Facial hair, deep voice, etc). Now relating back to what you and Mark said, this can be unhealthy and indicate poorer health. Is it possible that too much vitamins and minerals from our enriched "food" is the culprit? Who knows.
I was diagnosed with low T3 levels (hypothyroidism) compared to the average American who is most likely on a SAD diet. But I'm not overweight, and/or have any symptoms of hypothyroidism. Just some food for thought.. I completely avoid most processed foods, maybe they just over process our bodies.
Just focus on nutrition, let go of all other measures, height, weight etc., don't get too anal about the low carb thing.
Nutrition density on a high variety quality diet will ensure you become the best you, maybe taller, maybe not, it's not important.
Leg length has also been directly corrolated to CVD, so trying to manipulate growth characteristics may get the desired result, but there may be an unexpected price to pay.

No, I don't believe its too much vitamins or minerals. Not for a second. The postulated theory of hyperinsulinemia or even GH in your CAFO milk and meat stand a much better chance of being the culprit.
I thought that fasting and/or ketosis lowered IGF-1 levels?
Kids that are kept on a ketogenic diet have issues with temporary growth restriction. So I would guess that if you want to be taller you should NOT be particularly low carb (Not that you would need SAD levels of carbs, but just not ketogenic low carb all the time).
