I'm 27 yrs old, 5'8 and weight 155 trying to get back down to 135. I've been trying to lose weight since Jan. of this yr. and I've been watching what I've been eating, exercising for about 2 hrs. and I have not even lost 1 lbs. I don't know what I"m doing wrong, but I'm at the point that I canceled my gym membership. I've stopped for a few weeks, and now started back walking about 1.5 miles about 2 times per week. and been watching what I'm eating. but still have not lost anything. What am I doing wrong..
