Not a clue. Metabolism is fascinating! If science can figure this out, someone will make a fortune.
Why can two people of the same size eat the same number of calories, and the one will become obese and the other will lose weight?
Why are there skinny men and women out there who are desperate to gain some weight and stuffing thousands of calories into their mouths daily in a vain effort to gain some pounds, and their metabolisms burn up the calories as fast as they can eat them?
Why are there fat people out there who can eat 3000 low carb calories per day, and more, and lose weight on it, while the identical fat person standing next to them can eat 1500 low carb calories a day and remain in a stall forever?
The thing about calories is.. they work.. but you have to start at each individual's metabolic level, and that's the part that varies so greatly between people. So you can only put people on the same level field for weight loss when you have the correct handle on their current rate of calorie burn. Because of the difference in metabolic rates among us, the playing field is not remotely level for all of us, and that means the calorie numbers to make weight loss work are also not level. Not that they don't work. Just that the numbers aren't at the same starting point for everyone.
That's why we also have to take the numbers these calorie calculators give us for our UD calorie numbers with a big grain of salt. We use that number as our baseline for all of our JUDDDing, and if it's actually too high for us, because we have a much slower metabolism that the calculator couldn't factor in, we will be basing our JUDDD diet on a calorie figure that is too high for us. And that will probably mean either really, really slow weight loss, or even no weight loss. :sad:
That's why we tell folks they just have to start in somewhere, and then adjust their UD calorie number downward a bit if they aren't losing. Eventually they will find the place where their rate of metabolic burn is more than their caloric intake, and here comes weight loss.
