In Topic: what protien powder to buy

Well if you get a strait whey protein powder. That's just the protein from milk they take off making cheese, isolated and dehydrated right?

In the strictest sense I mean strictest sense, In-out=accumulation. In an impossible to test thought experiment for example.


In a static system, yes. Human metabolism is not a static system. That's what people aren't quite wrapping their heads around.

Also, now all I can think of is Gerard Butler spartan kicking people into a giant calorimeter.


Well no, even in a dynamic system, its still true. Now really you technically have to do a mass and energy balance. But, draw a box around any system, whatever happens in the box doesn't matter.

A simple example is a 5 gallon bucket with a hole in the bottom. If pour in 1 gallons a minute, less water will come out of the hole per minute than if you pour in 2 gallons a minute. Because of an increase in pressure. The total water put into the bucket minus the water that comes out the hole still equals how much water is in the bucket. This if you vary the input rate thoughout this is still true.

The real thing people are missing is that a mass and energy balance is not a fat balance. The differential between energy in and energy out is not equal to fat lost.

The reason they conflict is that one side is talking about thermodynamic balance, and the other side is talking about body composition.

In the strictest sense I mean strictest sense, In-out=accumulation. In an impossible to test thought experiment for example.

If you were to take a person and get an exact replicate of them. You then throw one of them in to a bomb calorimeter and burn them to see how many calories they have total from all tissue. Then you take the other one and feed him and exercise him with whatever combo you want to test. All the while measuring exactly (impossible) how what his energy he uses the entire time. Obviously you also record exactly what he consumes. Also, every time he goes to the bathroom its collected (urine and feces) and burned in the bomb calorimeter. Then after a time you throw him into the bomb calorimeter.

Energy in food - (Energy Used + Energy in waste) = Energy in second guy -Energy in first guy
