Me. I currently maintain a 2.3x bodyweight deadlift and 1.5x bench press while working a relatively tame & laid-back salaried dev job. Can't do IF (multi-day, anyways) without losing lean mass anymore. Used to be able to until I started plateauing on my lifts. My guess is as you gain more and more lean muscle mass, there's some arbitrary threshold (which differs person to person) at which your TDEE begins to exceed viable intake within a limited timeframe. I specify "viable intake" because your body's nutrient uptake rate per hour has some given limit - anything over that limit usually just gets pooped out later. Restricting timeframe for eating during the day (break my fast after work) seems to work out okay though.
