I'm 5'7", 165lbs at the moment.
Might not seem like much, but I have felt "fat" since I eclipsed 150lbs about 6-7 years ago. In high school, I weighed about 175 lbs and felt really fat. I dropped 35lbs in one summer before college, which was really hard but at age 18 that's a lot easier to do than it is now that I'm in my 30s.
The past 18 months, I've been going to the gym about twice a week, I lift for about 30 minutes then do a 3 mile run in about 23.5 minutes. I started out at 170lbs when I started back in the gym routine, and really haven't lost that much weight because that really hasn't been my goal, but am lifting a lot more weight than I ever could and a lot stronger.
However, I've still got a bit of a gut... I blame my eating habits. I love fast food (though it's usually roast beef or grilled chicken sandwiches), and I have this awful habit of eating chips at night right before bedtime. I can easily eat half a bag of Doritos 3-4 nights a week - if not for that, I think I'd be able to drop down to 150 pretty easily, or even down to 140 if I wanted to. At one time I dropped down to 125 in college, when I was running 5 miles at a time several times per week. But I know I can't do that anymore, I just don't have the time. Plus it seems like every couple months I am getting sick with something that sets me back and I miss a week at the gym... heck, I've had two bouts with pneumonia since November - it really makes it harder to run like I was and I've actually cut back to 2 miles at a time most days now because I just can't handle more at the pace I like to run.
Anyways, my goal is by June to be down to 150 lbs. If I don't get there I won't be too upset, but I should get close... I have always believed that the way is to eat less (and better), but stay active.
