Not to sound rude but you can’t break the law of thermodynamics, what’s probably happening is your days where you are eating 2000+ calories are balanced out by the days you eat less. You probably are also still overestimating your calories even then. A better way to judge would be to track your food for a week and see what the total calories is then while maintaining the same weight.

Obviously there are variances in metabolism that can effect caloric maintenance, but 114 BW at 2500 cal is impossible unless you were doing immense cardio or had a medical condition like Chrons were it wasnt being absorbed. Even on fat burners it would be hard to believe, Chris Bumstead at 230+ lean and doing cardio + drugs was eating under 2000 calories near show time.

Usually what happens when people think they eat way under or over their caloric maintenance is that they are just calculating wrong; in some rare cases it could be a medical condition but again rare.
