Very interesting (and long!) read.

Long story short, more protein is good. But some science behind it that might make your viewpoint shift...

    Seven excess calories per day...yikes.

    It's an interesting hypothesis for sure, and lines up with some of the things we already understand.

    To wit: our bodies need at least 15% of our calories to come from protein. In our obesogenic society, carbohydrates and fats are more readily available than protein, and in order to get the protein we need we eat more food. We become overweight as a result, but that's a compromise our bodies make in order to get sufficient protein - the relative costs of obesity being lower than the costs of having low levels of protein.

    Not understanding the state of research, it does seem to me that a lot of validation would be needed. Much of the article sounds like speculation or "just so" stories to me. It seems to me that the validation would not be incredibly difficult to do, however.

    Thanks AlabasterVerve, I posted on my way to lunch and forgot to link! Sorry all!

    Jruzer, yes, it would need to be tested in humans for more validation as the theory is based off of animal research - but it does help line up a lot of the things we know anecdotally about protein's role in our own diet.

    There's a salt leverage parallel where junk food sodium content is being reduced leading to greater consumption.

    I've seen the same theory also tied to a similar increase in weight in wild animals. The thought is that as the atmosphere has been increasing in CO2, plants have been producing more starch (greenhouse research shows increased CO2 increases plant size, but as nitrogen can still be limited, the plants increase sugar creation rather than increasing protein). With an increase in plant's starch to protein content ratios, animals are responding by having to eat more calories to reach sufficient protein.
