I think in general the concept of "bulking and cutting" is backwards. People are fixating on food as the determinant of anabolism and paying zero regard to training, when it should honestly be the other way around.
Nutrition is an aspect of recovery. You use it to recover from training. Training, in turn, tends to occur in blocks due to your ability TO recover. When you increase the volume of training, you increase the food intake to facilitate recovery. You'll be able to sustain this for a period of time (several months) before, eventually, the volume becomes too much to practically recover from. This would be your "bulk". Once you can no longer recover from training volume, you drop volume and increase intensity. During this period of time, greater recovery is not required, so food gets scaled down to match. This would be the cut.
Instead, what we witness is people that train in the exact same manner and only manipulate calories. They end up putting on the same amount of fat and taking it off over and over again
