Not really. I linked this blog post elsewhere in the thread which reviewed a study that indicated that 1.6g/kg was the optimal protein amount for fat loss. Even higher protein resulted in more weight loss, but less fat loss proportionally.

The blog post you linked is very good, but it doesn't support your claim. In fact, the article pretty clearly supports 1.6-1.8g/kg. The lowest recommendation I can infer is the ~0.9g/kg, which is the level at which muscle protein synthesis is maximized in sedentary individuals, though that's an entirely irrelevant metric to make a recommendation from.
