The great thing about these open forums is that everone can express their own opinion, right or wrong. There's no place for people with a "I'm right and you're wrong because I know it all" attitude. Nothing is accomplished in that matter. So tone down the attitude, Ball. We don't need your dogmatism.
Besides, there's more holes in the statements you made than in a piece of Swiss cheese.
"It is an undeniable and indisputable scientific fact that if a woamn eats 2000 calories a day she will weigh between 120 and 130 pounds. What is so tough about simply doing that?"
Weigh between 120 and 130 lbs of what? Let's be clear. It's true if this person ate a diet of complex carbs and quality protein and worked out hard, she might maintain her body weight. Millions of people in the East (China) are thin and healthy and still consume more calories than their Western counterparts, but it has to do with their diet and activity level. If this woman you're talking about sat around the house watching soap operas and ate 2000 calories of potato chips and chocolate cake, I can assure you she wouldn't weigh 120 to 130 lbs, and if she did, it certainly wouldn't be muscle. So let's cut out these blanket statements without qualifying them first because they simply are not true. You know, and I know, and everyone else on this forum knows that saying "It is an undeniable and indisputable scientific fact that if a woamn eats 2000 calories a day she will weigh between 120 and 130 pounds" is absurd. The "proof" to back that claim doesn't exist.
"If 2 women raise a ten pound weight 10 feet they are doing the same amount of work and therefore expending the same amount of calories".
Interesting! Let's look at that statement a little more closely.
"If 2 women raise a ten pound weight 10 feet they are doing the same amount of work..." I agree so far. Work = Force x Distance (weight x height), (if I remember my high school physics correctly!)
"...and therefore expending the same amount of calories". I disagree! See, I didn't say "Wrong!" They may do the same amount of work, but they don’t necessarily burn the the same number of calories. You quote the 2nd law of thermodynamics above, so you should know that no energy transfers are 100% efficient. If both of their bodies were 100% efficient they might burn the same calories. But no body is 100% efficient. So a fitter individual can do the same amount of work but use less oxygen and therefore burn fewer calories.
In order to find the efficiency of a body, the oxygen consumed must be measured, as it’s oxygen that is required for energy production. Once the amount of oxygen consumed is found, there is a conversion factor you multiply it by to find the calories burned. So again, forget the blanket statements. They don’t hold up to the facts.
"Certainly a 130 pound woman doing an hour of intense training is going to burn close to 1000 calories".
Explain that more fully to me. An individual running a marathon burns on average 2624 calories. So how can a 130 lb woman burn 1000 calories training intensely in only 1 hour? You forgot to subtract her RMR from your figure. A person is going to burn a certain number of calories just sitting around doing nothing - their RMR. So as I said, this number has to be subtracted from the figure given to get an accurate number of calories burned from activities.
There are other parts of you assertions that I would challenege, but this post is getting too long.
