Yes the the wastage comes to an end. But I’m my experience so far, muscle building isn’t the same. Right now, I’m finally at the stage where I can workout more often and not feel like dying. I’m tracking my calories once again and I’m going to try to cut some fat then bulk up on muscle like the old days. I expect less results because my body doesn’t feel like before.
In a few months, I’ll be able to tell you whether or not muscle can be made. But this is only after careful calorie tracking, macro tracking, lifting, and weighing in. Your mileage may vary from mine, though.
