First of all, sorry for delayed response.
Except of being very busy last days, I also encountered some problem with this board, perhaps there was some kind of update in progress.
Anyway, let's move on to the topic
You have asked if I am losing weight by exercise while I am taking healthy diet.
the answer is that I am not losing any weight while I keep a healthy diet, that's why I have to think about controlling my diet along with exercise. In fact I think if my exercise can only help me not gaining any further weight while I take a healthy diet, that'll be great.
Currently I don't take anything before going for jogging in the morning. I just wake up, put on some cloths and go....
some times I drink one or half glass of water before going to jogging, that's the maximum.
as far as a small break fast 1 hour before going to jogging is concern, I don't think that's possible for me because I just wake up and go, usually my partners have to wake me up in morning, because I don't wake up myself.
However, I am thinking about reducing my diet by little, so that it won't hurt my daily needs by much.
