Hungry all the time

In addition to good advice above (especially the question of whether you're fueling enough, and sleeping), I'd also ask whether you've changed something in the modality of your exercise and activity relatively recently, such as the form of exercising (y'know, swimming, cycling, weight lifting, etc.), the intensity of exercise (faster running, HIIT vs more moderate intervals, more frequent higher-intensity vs. lower-intensity workouts, that sort of thing); the duration of some exercise (even if eating back the higher calories); the frequency of exercise; or the intervals for recovery between exercises that put stress on the same muscle groups or body systems (like doing something on successive days that used to be every other day).

Some of us find that different exercises or intensities create more hunger than others, and it seems to differ by person (and sometimes even differs at different times for the same person). For example, for me, even quite moderate weight training seems to affect my appetite, in ways that even fairly intense cardio doesn't.

Also, don't assume that "eating clean" is necessarily getting you well-rounded nutrition. If you haven't, you might want to spot-check a couple of days for micronutrient levels, especially things that can relate to subtle fatigue like iron. Pills/supplements may not do the job as well as nutrients from food. I'll assume you've already tuned up your macro-level nutrition, if you're logging here.

Changes in daily life stress level might also contribute to appetite changes. Since you're already getting plenty of exercise, if stress is up, you might want to consider stress reduction techniques.

Best wishes!

Are you meeting fat and protein needs?

I find protein keeps me feeling full. Any carb and I get hungry. The only exception to that is a SMALL amount of ice cream (1/4 cup high quality) with yogurt and nuts to up the protein and cut the sweet taste is very satisfying and keeps me from being hungry.
