Again, you're way off the mark. 70% over the average resting HR of 70 is a whopping 120 beats per minute. Only a fragile 80 year-old couldn't handle that. That, three times a week for 30 min, is barely worth the trouble. Any normal healthy adult should have no problem getting their HR up around 60-70% of max for an hour or so a few times a week. That will burn plenty of calories.
What I'm getting at here is that you're hinging weight on food rather than exercise. While you are technically correct that everyone should be able to just eat right and maintain a healthy weight without all that pesky running around and sweating, this basically doesn't happen in reality. Most people will feel hungry if they follow this sort of diet. Eventually their willpower gives out, and they fall off the wagon. This is why just dieting almost invariably fails.
With exercise (and not the pathetic regimen you're describing), you give yourself a higher caloric ceiling each day thanks to the calories burned during exercise. As such, one can eat a relatively "normal" diet, feel full, and still lose weight. On top of this, you get all the neat benefits of exercise like lowered cholesterol.....bp......the nice endorphin buzz.....better endurance in the sack....etc.
See above. Exercise + diet > just diet. All goes back to people's lack of willpower. I never said you could exercise and then live on Butter-Flavor Crisco.
Again, you're demonizing exercise. Which is why I'm labeling you an idiot. :roll:
