Thoughts?  I'm clearly skeptical

A low protein, high carbohydrate diet may be the most effective for stimulating a hormone with life-extending and obesity-fighting benefits, according to the latest Australian research.

The study, published in the journal Cell Metabolism, paints a clearer picture of the role of Fibroblast Growth Factor 21 (FGF21), the so-called fountain of youth hormone produced primarily in the liver.

Previous studies have found that FGF21 plays a role in curbing appetite, moderating metabolism, improving the immune system and extending lifespan. It is also currently being used as a therapeutic target for diabetes but little is known about how this hormone is triggered and released in the body.

Now researchers at the University of Sydney’s Charles Perkins Centre have found that diets high in carbohydrate and low in protein are the best for boosting levels of FGF21 in mice.

Pretty sure low protein, high carb was in fact the mouse paleo diet, and not the exact opposite.
