I do the same thing that Pensguys does. It has taken me a long time to get to a sweet spot for me. BUT, now that I’m actually listening to my body and what it wants, I can stay within a range. Like on non-workout days I eat almost 30g less (protein) than when I work out and less fat … that is unless I’m starving that day. I lift HEAVY on the days I do lift (3x per week) adn I’m usually not that hungry on those days, but, the days after … especially if I had deadlifts I will be an EATING MACHINE! But anyways, I would suggest trying a range and see how that goes for you.
