The fact that height is mainly determined by genes is a logical or genetic fact?

Since the genes about height are not discovered and researches completely due to the technology, I am wondering the fact that height is mainly determined by genes is assertive or based on genetic evidences.
I am not skeptical about this matter of fact cuz I am not that retard but I am curious about the very original researches about it.
Are there multiple researchers who discovered this fact or just only 'logicists'?

It's mostly genetic.  Only the seriously malnourished would lose potential height.

But give it a rest, you guys talking about wanting the height you "should've" had and nothing more.  Live in the present.  You're a certain height now.  Does it cause you problems or distreses?

Here's one data point on how malnutrition can impact growth. There have been some couple studies measuring the final heights of people who were hospitalized for eating disorders such as anorexia nervosa in their teens. Teens that recovered from an ED were shown to have stunted growth compared to their genetic potential (calculated using the heights of their mothers and fathers); women fell 1 - 1.5 inches short of their predicted height, while men fell 2-3 inches short I believe. I don't remember off the top of my head if these numbers described an average or the standard deviation or what.
"Genetic potential" calculations have some degree of error, but I am guessing there was a control group or control statistics on how tall non-ED teens grow compared to their genetic potential.

Pretty intuitive that starvation during adolescence = stunted growth, but I think it's cool they attempted to quantify it. Searching "teens" "anorexia" "stunted growth" should bring up papers like this

It really wouldn't be possible for height to be determined by anything else, but it can be significantly influenced by environmental factors like nutrition and growth disorders.

Drug abuse, sleep deprivation and injury are also contributors to loss of potential height

Sure but malnutrition is actually a disease not just something like 'I am picky about food', 'I love cookies so I don't achieve enough nutritions' and similar stuffs. Malnutrition must be examined by medical tools or other professional methods I think.

Well I wouldn't equate anorexia nervosa to being "picky about food" (maybe this isn't what you are doing). In the most severe cases, these people are on the verge of death.

Malnutrition is an umbrella category describing situations where the body is not getting enough calories, other nutrients in the proper amounts, or it cannot absorb nutrients. Technically, if you only ate cookies, you would also be malnourished. I just don't think anyone has quantified height loss in people who get enough calories, but spend those calories on crap. My guess is it would be a very small loss compared to people who are not even meeting their caloric needs.

With the anorexia study I just meant to provide an example of some extent of malnourishment resulting in some measurable extent of height loss

So hypothetically, if someone only ate cookies and nothing else during all his growing years, how much height will be lost?
