milk & metabolism

according to my body reaction, i suspect that milk & metabolism have a reciprocal relationship or causal to be exact, the first toward the second. to rephrase in a more humanly term: today, after a few times beforehand, i'm convinced tat milk makes my tummy acting abnormally thru the frequent necessity to do a very normal human act of sitting over the top of a toilet bowl.

have i drunk slightly stale milk (again?!?), or does breastfeeding really do reducing the likelihood of obesity for babies in their later life?
