Well, weight training plays a huge (and required) role in maintaining muscle/strength while losing fat, but strictly in terms of causing fat loss, weight training doesn’t have much of an effect at all because it just doesn’t burn THAT many calories. Cardio generally burns more calories than weight training, but it’s still not THAT huge of an amount, especially for the amount of time it takes.
I have one question though. I think I’ve read most of your site at this stage and I think I can find most of the answer to my question but I can’t seem to find the complete answer and it would be nice to see it pulled together in one place. Now I understand the whole calorie deficit thing & I understand that you can create the deficit through diet & exercise. I also saw your article saying that, although weight training does have *some* effect on weight loss, its actually very small. I’ve also seen you virtually dismiss (:-)) cardio. The thing is, I haven’t seen all these things drawn together in one place. So: are you saying that changes to diet has BY FAR the greatest effect on fat loss? And that weight training and cardio have such a small effect on fat loss that, relative to diet, they are almost insignificant? Because that is the impression I’m getting. Actually – and I know this is not really possible – could you quantify their relative effects as you see them? e.g. diet 70%, cardio 20% weight training 10%. Again, I know, that’s not possible, but just to give a “feel” for their relative impacts. You can see what I’m getting at here: I’d like to get an idea for where to concentrate my efforts.
If you don’t have an established exercise routine, simply walking is the best first step toward weight loss. “Walking is a pretty good entry point for people,” says Gagliardi. This is particularly true if you have been out of the gym for a while and want to ease back into a workout routine. One small study published in The Journal of Exercise Nutrition & Biochemistry found that obese women who did a walking program for 50 to 70 minutes three days per week for 12 weeks significantly slashed their visceral fat compared to a sedentary control group.
