Here’s a study where they compared high protein low fat (HPLF) with low protein high hat (LPHF) and also medium protein, medium fat (MPMF) but low carb meals.
Here are the conclusions:
### Conclusions In subjects consuming low carbohydrate meals, higher concentrations of proteins to fat seem to have more favorable effects on postprandial appetite hormones.
In other words, the for hormones they looked at (ghrelin, an appetite-increasing hormone, and PYY, a peptide), these were better for higher protein.
This had the obvious shortcomings of only 8 MEN (yes, it’s almost always men), normal weight, although they gave all the different meals to all the men.
However, maybe people like me, who think higher protein is more filling, aren’t crazy. 
This could also explain why some people react differently, if they have a different response. With only 8 men in this study, that’s not enough to know how others who are overweight or who are female or who have messed up systems will react.
