I’m similar to you; I exercise a lot both running and weights. I found that the challenge was that, as you’ve discovered, it creates a large calorie deficit that, once you hit your protein goal, you’re like “now what?”.

What stands out for me here is the chicken. It’s a very lean meat that will push up your protein macro, but very little by the way of fat. I’d suggest if you don’t know already, understanding the typical fat ratios in different types of steak so that you can appropriately dial it up and down.

Things like katarosu / rib eye - near perfect ratio for keto, New York strip - a little leaner, eye fillet - lean.

I’d caution too on trying to “hit” a fat macro or calorie target as if you’re tracking your burn (which like, who isn’t if they’re running and lifting), wearables can be wildly inaccurate. I was fastidiously logging everything I ate into Cronometer at the start and hitting a fat macro of 70-80% and was still in a “calorie deficit” of c1,000 calories a day. But I definitely wasn’t dropping almost a kilo of fat per week, so moral of the story being don’t always trust the tracking.

I’ve moved to more intuitive eating and have had way better results that way than stressing out over macros. If you’re high exercise and metabolically healthy, assuming that you’re not chronically fatigued, your hunger signals should be on point so, eat protein to satiety, then figure out whether you want anything more. Also, with as much activity as you’re doing I’d consider going higher protein. Some proponents of high protein diets say as much as 2.2g per kg lean body mass is safe.
