I recommend more calories than most do. That’s because there's no such thing as a stagnant metabolic set-point. Instead, metabolism chases intake. So, if you want a bigger metabolism, you need a bigger food intake. And if you’re worried about fat gain with this approach, just use outcome-based decision making and adjust energy (calorie) intake every two weeks based on your results. Not much "damage" can take place in only two weeks.  So if you end up boosting your metabolism, you’ll be thanking me eternally.  And if it turns out you're consuming too much, you can just adjust down.
