I find this very wrong in a couple of ways. Firstly, yes you can lose weight through upping your BMR through introducing more muscle onto the body, essentially giving yourself a bigger engine. However, as you say you cannot outrun your fork, well you also cannot outlift your fork either. Your body burns its carbohydrate and fat stores when exercising through cardio, now if you're going to the gym and running on a treadmill for 20 minutes you're unlikely to burn much. But if you do this consistently outside multiple times a week, you will absolutely see changes provided you aren't overeating. This idea that cardio doesn't burn calories or help you lose weight is ludacris. If this was the case, every triathlete, cyclist or runner would be overweight.
