I'm talking about you recording the calories of everything that goes into your mouth for 14 days. Weigh yourself at day 1 and day 14 if you're the same weight then average out the calories and that is your maintenance. If you want to lose weight then you have to drop below that number. The number is yours and your alone.
But still **highly** inaccurate.
Daily metabolism can change based on changing activity levels, water intake, food choices, meal timing, sleep patterns, stress levels, medications, fluxuating hormone levels, weight changes, fat gain/loss, muscle gain/loss, supplementation.
Maybe within those 14 days you were under extreme stress, so your metabolism increased. Then, you use this "average" for maintenance and then find that you are gaining - because now your body stabilized. It is impossible to give a set number that will always work. You need to stick with a range and inc/dec based on losses/gains on a regular basis.
For example, to cut fat, it is best to go with 10-12xBW for caloric intake. This is a RANGE to play with. Take a 100lb female (for ease of numbers). Her cutting caloric intake would be 1000-1200 calories per day. So she would start at about 1200 and stick with it for a few weeks. If nothing happens, then drop is a couple calories (like 30-50) and monitor that for a few weeks. Repeat as necessary.
But eventually, it will have to stop. You simply cannot keep dropping calories below maintenance. AT this logic, eventually you will be eating nothing. If you consistently keep plateauing with diet - then you midify training methods and food choices. Calories should not be drastically reduced on a consistent basis.
The "rule" you state is simply NOT a rule. There is no reason why you need to drastically go below maintenance to lose fat. And there is no reason why you have to keep reducing calories over and over and over due to plateaus. It is all about diet and training. Diet meaning food choices - not necessarily caloric intake.
