I don’t get the obsession with fiber. Cramming as much fiber as you can into every meal makes eating a slog and makes it less likely you’ll be able to pack in all your daily macronutrients, because you’ll feel too full to eat.
As to your macronutrient concern, unless you are trying to eat 4000+ calories which is about when it becomes a chore to eat (I once had a job where I lost weight eating less than that), high fiber food isn’t going to make it hard to get your macro nutrients with most modern diets. And foods high in fiber tend to have more micronutrients. For instance the germ in whole grain is literally the nutrients needed to kickstart a seed into a plant.
