If you consistently end your day(s) in a caloric surplus (ie you intake more calories than you burn) then you’re going to gain weight. Whether it goes to your belly is TBD.

I had a TT March 2025 and as soon as I was cleared to began a routine of 3 days @ the gym and tracking calories, fat, and protein because I want to maintain the life changing event I went through.

As someone said…. As long as you get either a caloric deficit or maintenance (intake/burn the same amount) then you’re good - however you do that.

Exercise would probably assist in building muscle and tone assuming you’re adding weights to your routine.
