Metabolism

Recently I've been putting more effort into actively gaining. Eating more and more frequently and the like, but not as much as I used to. But I've noticed that with less effort than I used to put in I feel like I am getting more out of it.
Part of this could be the sabbatical I took from gaining, but I think a larger part is my metabolism slowing down. It's not something I expected, as I never thought I had a particularly fast metabolism, so the effect is odd for me to consider. Especially since I don't think my age is that significant (but apparently men experience decreases around 25). It is actually kind of frustrating, since I had a lot of trouble gaining when I was younger.
Has anyone else noticed something similar?
