The term "lean mass hyper-responder" was coined by software engineer David Feldman on July 3, 2017 while posting in his low-carb diet blog: "Cholesterol Code." The blog post called "Are you a Lean Mass Hyper-responder?" quickly circulated through the low-carb community.
As background, the original term "hyper-responder" was already used by dietary professionals for years prior to Feldman's blog post. And in dietary literature, a "hyper-responder" is someone who adopts a low-carb diet, then experiences dramatic cholesterol elevation. So when Feldman wrote his 2017 blog article, he co-opted "hyper-responder," and crafted his new term "lean mass hyper-responder" to describe what he believes is a metabolically unique sub-set of all hyper-responders. Specifically, some hyper-responders begin a low-carb diet while already in possession of a very lean body mass. And yet in spite of this, they still --quite counter-intuitively-- respond with extreme cholesterol elevation. Additionally, these subjects experience a marked decrease in triglycerides, while exhibiting excellent metabolic health. The entire phenomenon defied a long-standing metabolic theory called "The Lipid Energy Model," presenting a scientific conundrum for Feldman.
Feldman believed that all this was a significant observation worth exploring. And his efforts eventually led to a 2023 research project called "The Lean Mass Hyper-Responder Study" led by Dr. Matthew Budoff and Dr. Nicholas Norwitz at Lundquist, UCLA.

IN A SENTENCE: "Steve has always been a tall, skinny, beanpole of a guy. And then when he went on the carnivore diet, he was still skinny, but his cholesterol went through the roof. His doc said that overall he's pretty healthy, so he might just be a lean mass hyper-responder."

Get the lean green mean cream machinemug. A flirtatious body language where you move in slightly closer to someone's personal space during a conversation but in a very subtle way.
Typically, if the other person does not step back it is because they do not mind, or perhaps they are feeling flirtatious also. If the person does steps back or makes room for your personal space, it is their body language saying please give me some room, and you should definitely move back. Do not try this move when someone's back is to a wall or chair where they cannot get their personal space back.
From the movie "While You Were Sleeping" (usually shown around the holidays) with Sandra Bullock and Bill Pulman.

The character of Jack implies to Lucy that she and her macho yet blundering neighbor must be interested in each other because he gave her flowers and then she "leaned". She is somewhat annoyed by this and so he explains more about what leaning is: "It was a lot different from hugging. Hugging's very different. Hugging that involves arms and hands; and leaning is whole bodies moving in like this (leans toward her suggestively) Leaning involves wanting, and accepting... leaning". The joke at the end of the scene is her neighbor asking if Jack is bothering Lucy because it looks like he's "leaning".

Accepting the fact that being lean (<=15% body fat) is optimal for male health and attractiveness. A person who believes this is said to be lean pilled.
This belief exists to counter the narrative pushed by powerlifters and perma bulkers, which states that one should just get as big as possible and prioritize lifting numbers above everything else.

Friend: What happened to you? You used to be so strong and swole!
Me: I decided that feeling and looking my best is better than being able to bench 4 plates. I took the lean pill.
