Lean Mass Hyper-Responder

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."

Lean pill

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.

the lean doggy

A sex position that is sometimes painful to the female during sex. You take a sturdy object that is about the same height of the female's armpits used for her to lean on while the male is standing behind the woman and humps her in either the ass or the vagina. This will cause an orgasm for both the male and the female.
Dave: Hey babe, what position do you want to try now?
Brittany: I don't know. What did you have in mind?
Dave: I think we should do the lean doggy. Grab that table, stand it up, lean on it, and then let me hump you. I
Brittany: Wouldn't that hurt?
Dave: Yes, but it will give you a very long orgasm.
Brittany: Okay, only because I haven't had an orgasm from you since our honeymoon 4 years ago.

man lean

The man lean consists of placing both arms (one on top of the other) on a balcony railing, and adopting a facial expression akin to that of one getting lost in fond memories of the past, while silently weighing up the pros and cons of waiting for one's partner to finally finish their shopping against vaulting the balcony and ending their suffering. Most commonly occurs in shopping centres/malls, and is similar in many ways to the man chair, although takes place outside of the store. A true form of silent struggle. Next time you see a man lean in progress, why not slip a brother a thumbs up, to let him know that things are going to be okay.
"Yo, dude, check it out, you see that right there? Man lean."

"Woah, he looks so...lost..."

"Poor guy, he's been leaning for well over half an hour, I don't think he's gonna last much longer."
"Inconsiderate bitches. Let's go talk to him."

"Hey, chin up, brother. You're fighting the good fight."

"Thanks, guys. I-I really needed that."
