Maybe your body is in a plateau. Or your body is use to your exercise routine and just stores enough nutrients to keep you at the same weight.

When I was training for my first HM I didn't lose weight. It felt like my body would not "let me" lose weight and train at the same time. After I completed the HM, I introduced bicycling to my weekly exercise and lost 10 pounds. I also evaluated my diet adding more vegetables, cutting down pastries (one of my weaknesses), drinking more water (less soda).

Don't weigh daily, once a week is good. Measure yourself as well to see your progress and keep motivated. Perhaps you are gaining muscle...

Change your running a little, a speed day, a long run day just to confuse your body and spark some weight movement.

Sometimes when you don't even think about your weight and find your healthy lifestyle balance, the weight loss follows.

It completely motivates me, but it has been unsuccessful to date. I do not want to have the regret that I wonder how fast I could have been if I wasn't always > 200#

Going from 300 to 210 was a battle. Going from 210 to 170 - I can't figure out. 6'2 male BTW.

Great topic.

I'm in a very similar situation; and about the same size (an inch shorter, a little bigger). I fluccuate between the high 150s to high 160s. Last year while attending Weight Watchers I got to 144 lbs briefly, and held in the low to mid 150s, but I lost focus on Weight Watchers when I started training for the New York City Marathon and never really got it back. (I went back the first few months of the year and got down to the low 150s, but I was miserable and realized I needed to find another way.)

I've been losing weight in stops and starts for the past eight years, started at over 250 lbs. I started running when I was about 220 and have thought that this would help me be motivated to lose weight. It hasn't. I've kept running because I love it. It is a good thing, because I am a terrible runner--I absolutely suck at it.

There is a little part of me still somewhere inside that hopes if I could ever get to a "good" weight and stay there that I'd be able to run a "normal" pace (I'd be thrilled with 10 minute miles--something I've never even been close to). I don't run much faster at 165 than I did at 220. At 150, I still struggled to run a 12 minute mile. If I could ever get to my dream weight of 135 I don't know it would make all that much difference. This sucks the life out of me.

I like to exercise; but it only helps me with weight loss in that I'm more likely to make good choices when I'm exercising. I have to restrict what I eat in order to lose weight and that is hard to do for life and hard to do with so little pay-off (as regards running).

I don't really care how I look (it is never going to be good enough for me, and I've got way too much loose skin to ever think I'd be cute). I'd like to be lighter becaue like the OP, I do think it would be easier on my joints, I'd be less injury-prone, and that running would be easier all around.

Don't know if it will ever happen, but I'll continue to try.
