This is pretty much why i try to avoid these "scientific" debates when it comes to gaining muscle or losing weight. Because there are so many different view points and studies..blah blah...just go by experience and what works for you.
Experience > Science.
So in your case, your experience allows you to just cut back on food and you can lose the weight .
It was in my college psychology book. I'm sure they wouldn't lie to me...right?
Anyhow, all i was trying to prove was that after a while when you maintain the same weight your body get used to it, doesn't want to change, and when you do try to change starts lowering/raising metabolism and releasing hunger hormones to make you eat more and get you back to that "normal" weight. Which is true I believe, otherwise everyone would be able to lose weight pretty easily without having to deal with hunger and fighting their metabolism.
I just notice when I workout, my appetite goes down. That's one of the reasons why it is easy for me to cut back. Guess my body is messed up....lol
