The following is a sneak-peek draft Answer to a feature Question; for the pending Manuscript entire re-write and rebranding to sufficiently complete. Live-it-forward  ~ AW.

"How do I determine satiety levels through diet?" Two possible methods.

There are two (2) methodologies, despite subjective in their own accuracy. Nonetheless - they represent objective means congruent within our scientific & philosophic theme of exclusion and reinclusions.

1. Calorie Cycling
   This is arguably the most easiest and perhaps advisable for readers new to calorie restrictions and/or simply exclusion protocols in general.
   Establish and determine a baseline experience firstly through TDEE intakes, revise, and adjust. Whatever calorie intake the reader habituate as satiate - that is where hunger responses, and/or cues are maintained indifferently one day to the next, and whatever calorie intake determines and maintains their current weight ~ with as few deviations ~ would generally be loosely accepted as a baseline experience here for us to take note.
2. Macronutrient manipulation
   This may yet be reserved only amongst readers who have already found their “baseline” experience. Perhaps through a number of years in-between low carbohydrate and intermittent fasting.
   As readers may at some stage transition towards carbohydrate reduction, especially also its cyclical approaches ~ manipulation of various macronutrients would thus become applicable. Protein in particular would be the priority to adjust as it is arguably the macronutrient most interchangeable, even in hypocaloric plans to respect all needs of sustaining against stressors be it metabolic and/or environmental. 

Depending on readers’ exclusion and reinclusion experience, #1 ~ calorie cycling would be the most intuitive “starting point” were This Author (AW) be asked over what he would recommend to most dieters beginners and experienced alike. However of course not knowing a reader’s absolute granularity(s) in terms of intolerances, biochemistry, current metabolism etc ~ it is only a hypothetical advice and as far as advices go, time is the only last determining factor.

If there is one macronutrient This Author (AW) would generally not identify as “the” satiety factor, is Fibre intake.

While readers are certainly remain encouraged to experiment and tinker with fibre no differently than other macronutrients, it is not by any means a qualitative-enough macronutrient for it to be considered “essential”. Because of its impedance (think "resistance") at affecting every other nutrients be it delivery and uptake. It makes logical sense, that any delays or prevention in nutrient uptake should be questioned. 

Isolating as much variables therefore is the goal here at determining  what is truly the “essential” amongst macronutrients. Consequently we’d examine macromolecules that would have 1). Direct calorific value and 2). Direct sort of building (anabolic) and/or supportive features to the physiology.

Of all four macronutrients ~ Proteins, Fats and Carbohydrates qualify in our assessment, for the above regards.  Fibre, on the other hand, arguably is not elligible in our criteria, for a number of reasons.

Some argue fervently that it is a nutrient for the gut. Proclaimed as such precursor to short chain fatty acids. But it remains enzymatically resistant, by definition, for metabolic utilisation other than adding “bulk”, mechanically speaking. Were we to examine fibre, by itself, the indigestible component that is away from its wholefood sources ~ then we should accept that one way or another ~ that it is by itself, in isolation ~ dubious in nutritional value because of how resistive it is against our digestive enzymes. 

Another noteworthy reason is the questionably impractical, if not hazardous experiment,  if one were to exclusively, by that we shall mean exclusively ~ attests  on fibre alone in the expense of other macronutrient. Extreme thirst, if fluid intakes are inadequate~would become likely, and thereby prompts a health hazard.

Irrespective, This Author (AW) wishes to console once again ~ that Fibre is by no means to be eliminated to absolute abstinence. Unless troubleshooting for FODMAP tolerance assessment, fibre should be used judiciously.

Live it forward,

AW.
