IF with regards to a caloric surplus

Hi all,

​

New to IF. I did read the sticky but had a few questions to clarify. My purpose to IF is reducing BF/increasing energy levels and overall health. I currently eat a slight caloric surplus a day and would be going into IF to see if I could lose BF on maintenance intervals/possibly continue to gain muscle with a slight caloric intake.

​

I lift/teach wrestling around 4-5 nights a week and have a fair mix of strength and cardio. Current macros are around 3000 calories/day at 6ft 1 185lbs. Ideally, I'd walk around at 180 with the option to push higher with leaner gains in the future.

​

Any advice on how to calc my macros/such? Just similar status/maint? Any concerns regarding athletic performance?

​

thanks
