I think cardio is key. It's definitely a more efficient way to burn calories. Check out a site like caloriesperhour.com. You will burn ~150 calories in 30 minutes of moderate weight lifting, vs. 400 calories in 30 minutes on a stairmaster, or 260 calories for brisk walking, or 364 calories for moderate biking. From what I understand, the metabolic boost of weight lifting is really minimal, not enough to burn significant calories. (Runner's World recently did a long article about this, but unfortunately it's not online -- both the post-lifting "boost" and the metabolic effect of having the extra muscle added up to maybe 30 or 50? extra calories burned per day.)

Could you possibly walk to and from the gym to supplement your weightlifting? Or maybe get on the train or bus a few stops down to sneak in 15 minutes of walking each way? I guess the weather will make this a challenge soon.

Good luck with the SB. I am a carb and sugar addict and the thought of breaking my bad habits appeals to me -- I should take the plunge.

Thanks for the comment Ariel - it is very interesting to me. Do you know what issue of Runner's World this article was in? My neighbors downstairs have a subscription to Runner's World and might still have the issue kicking around. I'd love to read it, because what you described above runs contrary to what I've read over and over about the benefits of weight training. Do a google search on weight training metabolic effect and you will find thousands of pages extolling the virtues of weight training and the effect it has on metabolism. The figure I've read is that each pound you add will burn 30-50 extra calories each day. If you can put on save five pounds, you can end up using a lot more energy just doing what you usually do. Could all those sites be wrong? I'm sure it's a possibility, but it seems unlikely to me (I've also read about these benefits in magazines and books by serious health and fitness guru's). Still, I would love to have more information, or at least to hear Runner's World's take on it.

I love weight lifting - I'm not giving it up. My plan right now is to mix in a couple of intense cardio sessions a week, meaning I'm going to the gym five days a week. I've been doing this the last two weeks, and it seems to be working well so far.

I poked around some more and found the article online: http://tinyurl.com/9h8e9

(Incidentally, that whole series of "Enduring Questions" articles is quite interesting.)

And of course I would never suggest you give up weight training -- it's great for lots of reasons -- just that you add more cardio, which it sounds like you're doing.

Pertaining to the weight issue, surely you understand that as you replace fatty tissue with muscle, you will not lose weight, but may even gain a pound or two. Fat weighs considerably less!

Truly believe that weight training is the key here. Sure, cardio is a vital component in transforming your body shape and size, and you can further capitalize on that with a targeted weight training program like the one in this link.

There's wealth of research out there showing that more muscle translates to a greater energy requirement for the body. So, as your muscle mass increases, your body quite simply taxes you for more energy throughout the day just to keep going. Whereas the benefits of cardio just by itself tend not to pervade quite so far beyond the duration of time you are actually training.

Hope that makes sense. There's a whole load more details surrounding the issue if you want to delve deeper. You can get a fresh perspective, if you like, by taking a look at the link or the URL.

Very best of luck to you,
