DIET not CARDIO is the key.
Your body will metabolize muscle mass just as well as it will fat. If anything it's easier for your body to metabolize muscle mass (4 calories per gram of muscle) than it is for it to metabolize fat. (9 calories per gram) -
if long cardio is so good, how come none of those endurance cyclists while lean are not shredded with evident muscularity. Yet, it's the sprinters who look like they are chiseled out of marble ??
Sure the diet is one of the biggest factor when losing fat. But cardio is another big factor. Your statement "DIET not CARDIO is the key" is very true, but check this out...
Here is what research showed:
It has been shown that dieting alone leads to a greater reduction in visceral fat. The Visceral is the fat that protects your internal organs. While you may be losing weight just dieting, your appearance remains the same.
But exercise (lifting) has a been found to have a greater impact on subcutaneous fat. This is the fat that is stored just under our skin. This is the fat that has the biggest impact on the way we look.
The research was done on women. Something to think about.
Another research showed how important is dieting combined with training.
Method Weight loss
Aerobic exercise - 7 pounds
Restricted calorie diet - 17 pounds
Exercise & diet - 20 pounds
This showed that when and if you exercise it served to completely prevent the decline of fat burning. People whom only dieted lost that capacity to burn fat.
also..
"Japanese scientists have discovered that a moderate aerobic exercise program can reduce subcutaneous tissue to a greater extent than diet alone . In contrast, diets appear to have a greater effect on the fat that surrounds the internal organs (known as visceral fat). "
