Alternatively you can determine roughly the same amount using energy conversion Each pound in the body requires about 80joules a day to function healthily.
In my case this means I would need to eat for a 125lb target 80*125 = 10000J
1Kcal = 4.19Joules
10000/4.19 = 2386Kcal
2386Kcal to generate enough Energy for my 125 pounds to function each day...without weight gain or loss.
Which is about the same as my above BMR*HBE calculation. (which I rounded up to 2400 1500(bmr)*1.55 = = 2320Kcal)

I hate to be one of those people, but I guess I have no choice. There is a big difference between a Calorie and and a calorie. It is a difference by a factor of one thousand. In other words:
1 Kcal != 4.19 joules
1 Calorie != 4.19 joules
1 calorie = 4.19 joules
1Kcal = 1000 calories
It is not an aesthetic quibble, because on the food you will see a Calories listed, and not calories.
There is no difference between Calorie and calorie. a kcal (little k little c is very very important) is 1000 Calories, a Kcal or kCal is a kintec calorie used in energy conversion (big k or little k followed C as opposite is very very important.)
But in either regard they should really come up with standard terms, in Canada we see 3 different expressions on our sh*t. Calorie/calorie/kCal all represent 1 unit of energy. kcals represent 1000 of them.
This is why nutritionits want to have the term Calorie eliminated out right, and Joules and Kilojoules to be used instead...they don't get much luck. Most calories listed are actually *1000 which makes things even more confusing...which is why most nutritionits have just gone to BMR instead of Energy based conversion (if you can't beat em join em) Not that it matters, if you mutliply both sides by 1000 you get the same sh*t, if you divide both sides by 1000 you get the same sh*t.
Ultimately they all mean the same thing at the end of the day in terms of the science behind it. It is a representation of a quantity of energy in this case Joules, and really should be represented as such...granted im sure retards would become confused and try and eat batteries because they have an out put of joules as well...actually thats probably why they won't change it.
Also you raise a good point, most people don't know that 1 Calorie as seen on their food is actually 1000 calories...we just axed the old KILO from the name a long time ago. If you eat something that has 4 Calories, its actually 4000 calories., but again that makes no difference in the math as long as you do everything in like terms. the errors come when people add 10 Calories as 10 to calories of 425. Thinking they only ate 435 when they actually ate 10425. But again science is irrelevant apparently because the terms are used interchangeably anyway. I know there isn't 9000 calories in my Yogurt that is labeled as 90 Cal, 90 cal is much more accurate, I know because my little Yogurt does not give me 377000 Joules of Energy if it did I would be a fat *** ************* with about 30 times more energy in system then I consume in day.
So again largely irrelevant to the discussion...but good points none the less.
