Another factor controlling P-ratio is insulin sensitivity which refers to how well or how poorly a given tissue responds to the hormone insulin. Now, insulin is a storage hormone, affecting nutrient storage in tissues such as liver, muscle and fat cells. In that same ideal world, we’d have high insulin sensitivity in skeletal muscle (as this would tend to drive more calories into muscle) and poor insulin sensitivity in fat cells (making it harder to store calories there). This is especially true when you’re trying to gain muscle.
In contrast, when you diet, it’s actually better to be insulin resistant (note that two of the most effective diet drugs, GH and clenbuterol/ephedrine cause insulin resistance). By limiting the muscle’s use of glucose for fuel, you not only spare glucose for use by the brain, but you increase the muscles use of fatty acids for fuel.
In addition to hormonal advantages, it’s likely that the genetic elite have high skeletal muscle insulin sensitivity. They store tremendous amounts of calories in muscle which leaves less to go to fat cells. Their bodies also don’t have to release as much insulin in response to food intake.
In contrast, individuals with poor skeletal muscle insulin sensitivity tend to overproduce insulin, don’t store calories in muscle well (part of why they have trouble getting a pump, poor glycogen storage in muscle cells) and tend to spill calories over to fat cells more effectively.
So what controls insulin sensitivity? As always, a host of factors. One is simply genetic, folks can vary 10 fold in their sensitivity to insulin. Another is diet. Diets high in carbohydrates (especially highly refined carbohydrates), saturated fats and low in fiber tend to impair insulin sensitivity. Diets with lowered carbohydrates (or less refined sources), healthier fats (fish oils, monounsaturated fats like olive oil) and higher fiber intakes invariably improve insulin sensitivity.
so a diet in a low carbs and healthy fats would make your inuslin sensitivty better for storing muscles with calories as to fat?

valid arguments. but then what macronutrient would you reccomend in place? i'd think raising fat would have benefits hormonaly to an extent and protein can only be raised so high. also isnt insulin anabolic?
You are not a fragile ornament ready to collapse into an exhausted mass of goo simply because you squatted more than once in a 7-day week.
It'd be like preparing your entire life to bang 100 chicks in a row, getting tan, hitting the gym, making sure your hair looks right and reading the Kama Sutra, only to realize when you get there that you're gay and cannot get hard in the presence of women.

Is there a way to actually measure insulin sensitivity? Like, can you get a proper reading that tells you how insulin sensitive/resistant you are and then construct a diet accordingly? I'd assume this is somewhat similar to what diabetics (whom being insulin resistant obviously) would do.
Sorry if I dungoofed.

Progressive overload + Energy surplus + Sufficient Protein = Bulk
Naties have very little control over various hormonal levels, insulin sensitivity, androgen density and distribution etc...Correlation does not imply causation. The Plural of "anecdote" is not "evidence".
When you believe in things you don't understand you suffer, superstition aint the way.
Lets Not talk about what COULD be, nor what WOULD be, but rather what really is.
I'm not an MD, nor am I a bro scientist.
