I found this out myself, lifting heavy for the last few weeks. Diet isn't perfect, but pants are fitting looser and I'm gaining weight. Since I haven't lifted in awhile this is to be expected. I'm sure the scale will eventually turn the other way. I've been keeping my cardio moderate for 3 times a week but focusing on big lifts that hit major muscle groups. Basically old school weight training until I get dialed in on my protocol.
Weirdly enough, I didn't lose much strength in my bench or squat after a 10 month layoff, just a little shaky in balancing the weight
