1.45 minutes to an hour burns roughly 500 calories if you had spent that time on weights, structured to provide you with cardio you would lose fat not weight.
2.Let the diet do the hard fat loss and the gym retain the muscle
3.Its all semantics on the machine and going past 30 minutes you will be burning more alternative energy sources not fat to answer your question hence long distance runners are generaly lean not retaining much muscle mass at all
1. says who? more of a myth. 'lose fat not weight'? that makes no sense. doesn't fat weigh something?
2. they go hand in hand. like i said before, if you only had "one" to chose from, diet is the "one". all three is optimal. duh...
3. what the hell is a "alternative energy souuces"? you either burn fat or carbs, protein on very very very limited basis. btw, the longer one does aerobic exercise the more he utilizes fat as fuel. distance runners have optimal ratio of muscle for their body type and distance.

Thanks, US, for the voice of reason. Diet and exercise will help you lose weight. How much fat one burns depends on age, genes, and mostly how fit you are. Specifically, it depends on how efficient one is at burning fat. The more sedentary person is not an efficient fat burner. The more cardio you do, effectively, the more efficient you become. Where I teach group fitness, some of our classes alternate between endurance and interval training.
The endurance classes focus on fat burning; one is working below the anaerobic threshold. This is the theoretical point where a person stops burning fat. In actuality, this is the peak where one burns fat. After this point, the fat burning drops.
So, in the interval classes, one is pushed above the anaerobic threshold. I call the area about this point, the adaptation area. You are telling your body that is must adapt to the additional effort. You go to this point to make your body more efficient at burning fat.

The charts we use in our studios and throughout the exercise floor utilize five zones. One is encouraged to use a heart rate monitor in all of our cardio classes. As an instructor, the heart rate monitor is part of our uniform. I use mine whenever I do cardio with the exception of when I go to Choi Kwang Do (martial arts) classes.
I have to say that I lost about 5 percent more body fat by eating more frequently throughout the day. I added more fruits, nuts and vegetables.
Right now, I have to add a little more protein to gain a little more muscle. All in all, I do live by the healthy eating, cardio, and muscle strength and endurance philosophy.
