How easily one can lose weight seems to be more than calories in and calories out. Women with PCOS struggle mightily with weight. Having said that, I'm sure if you put a person in a box for 21 days without food you will observe a net weight change, but I'm sure the speed at which weightloss occurs or is observed will include other factors beyond calories in and out.

The Alone show is pretty interesting as an example of what could happen being in a box with no food. Men and women of all shapes and sizes go into that show and they all just slough off weight, like over a pound a day sometimes, and struggle bringing in enough food for their body to not starve. Many are medically discharged from the show if they lose too much weight too fast where it puts their internal organs at risk.

There's a psychological component to sticking to a diet for sure, but no, a calorie deficit of the same amount will result in the same weight loss rate.
People locked in a box will not be able to cheat and will demonstrate this.

Could also be that the incredibly complex digestive system isn't just a food mulcher but is capable of moderating caloric intake based on any number of parameters.

Eat a high-fat meal or a can of Pringles with Orlistat, then you'll have an idea of what happens if your digestive system fails to extract calories from what you eat. Trust me, you'll know.
No, our digestive tracts are extremely good at extracting any and all usable calories from our food.
100% of the time, when someone makes this claim, they are mis-estimating either their intake or expenditure, or not tracking for a long enough time period to escape the error bars inherent in daily hydration variance.
That's only one side of the equation.
It is a basically proven fact (and largely implied by physics) that `calorie intake - expenditure = net weight change`. That is pretty much beyond dispute.
It is also true that some things affect expenditure, and it seems likely that most people have a "set point" that your body attempts to return to. This is also almost certainly changeable, as people have managed to change it in the past. (And this is less surely true than other things known.)
So yes, it's entirely possible to eat "inconsistently" and not have net weight change, your body is probably subconciously causing you to eat less after you eat large meals, and vice versa. Or possibly causing you to expend more energy after large meals.
