I would say, in the short run it is very well possible to gain muscle tissue at a caloric deficit.
I have gained up to one third of an inch in preperation of a contest. Secondly, most bodybuilders know the muscle memory phenomenon. So if you are coming off a long lay off and got out of shape, you might be able to rebuild muscle easily, even why losing fat on very low calories.
I don’t like the calorie concept anyways. It is useful because calories correlate with the amount of food you ingest and this will help you find your baseline levels of food you need to grow, get ripped, etc.
But actually, we do not burn anything in our bodies. We eat foods and they are eventually broken down into diffrent kinds of moecules which will then enter diffrent biochemical pathways. There is a metabolic reaction to everything we eat and there is also such a thing like a metabolic burden that comes with certain foods.
I used to eat tons of pasta and bread in my early years as a bodybuilder and just didn’t gain quality muscle mass. Only after eliminating gluten from my diet the ratio of muscle/fat gains improved. I have no scientific explanation at hand, but I could imaginge that I am sensitive to gluten proteins and they led to either inflammed gut and malabsorbion of essential nutrients or to somehow altered blood or cell chemistry.
I used to eat 5500+ calories then and didn’t gain weight, or if I gained weight it was mostly fat.
Nowadays I eat between 2800-3200 calories - or the equivalent of quality foods - and am much stronger and heavier than back then.
While being on a diet with 5k calories I would have considered 3k calories a caloric deficit. Which it obviously is not.
Further, I think that it has been shown that the recruitment of satellite cells in the muscle lamnia is not energy (food intake) dependent.
All in all I believe it’s musch more important to think “nutrients” rather than calories. Which makes it difficult to define the term decicit.
Hypothetically, if someone eats “the perfect foods” only, the ones he/she can eat with no adverse reaction, etc. (no gluten for me, e.g.), I believe he/she could still make gains on a deficit in the short run. Either due to new stimuli for the recruitment of satellite cells or due to muscle memory effect.
However, in the long run, I don’t see a chance of making gains on a nutrient deficit (which correlates with calories - so: not possible on caloric deficit on the long run).
Just my 0.02

You made a great point on the malabsorption of certain nutrients, which will completely differ from person to person.
It also depends on the “types” of nutrients being eaten. If you have a complete carb vs a simple carb you will lose calories digesting the more complex carb even though it yields more nutrient value, so I agree calories are not the deciding factor here its the quality of the food + absorption of nutrients ( we lose a certain % of everything we eat) + stimulating muscle tissue.
I think it can ( and I’ve done it) be done in a short time frame but over time it just wont happen.
