Context The role of diet composition in response to overeating and energy dissipation in humans is unclear.
Objective To evaluate the effects of overconsumption of low, normal, and high protein diets on weight gain, energy expenditure, and body composition.
———————————————————————————————
Conclusions Among persons living in a controlled setting, calories alone account for the increase in fat; protein affected energy expenditure and storage of lean body mass, but not body fat storage.

The paper is fairly involved, as it is basic research, but if you go down to the comments section, it outlines what they found about how the body deals with fat/protein/carbohydrate in different proportions.
In the end though, they went back to the old energy in – energy out paradigm.
