There is no single study where any participant has lost the amount weight of weight predicted by the calorie deficit. Why? Its quite simple the human body is not a closed system like a bomb calorimeter and therefore the calories in < calories out will never hold true. Every weight loss study based on calories in < calories out eventually plateaus! why? There is a mechanism when the brain thinks its starving it will store any calories beyond the bare minimum to fat.
How is a plateau the logical result of the brain entering starvation mode? Starvation level calorie storage would make far more sense as the result of creating too severe of a caloric deficit, forcing the body to make a sudden adjustment, rather than maintaining a moderate deficit over a longer period of time.
As long as the amount of calories brought in meets that which is needed to maintain the BMR, the calories above that should be able to be fairly freely distributed (caloric maintenance). The catch is that person to person BMR can vary wildly, and if the change in diet is not accompanied by a change in lifestyle the gains (losses) eventually become more difficult to maintain as there is less fat there is to burn, making it a less optimal resource for energy, making it more difficult to induce your body to burn it. Further finding an exact BMR, understanding just how many calories are used by a given activity, how many calories are needed for maintenance/muscle building, and what exactly determines which resources are tapped for energy is still not concrete knowledge of course, but the principal of it is pretty sound.
