I just saw your profile and noticed you're 31 years old!! Do us all a favor and grow up.
No one of any age has ever talked to me like you are in person. Calling me an "uneducated idiot." It only happens on message boards. I wonder why that is...Hmm!
If we were talking face to face you'd be alot less aggressive than you are now. I guarantee that. If you threw around as many insult as you do online in face to face speak...You probably wouldn't have many teeth left!
You're probably one of those 115lb guys who can't act tough around people face to face so he gets his kicks throwing pointless insults on message boards to anyone who simply disagrees with them.
Notice the first post in this thread and you're calling me an "Idiot". That says alot about YOUR mauturity level..Or lack thereof.
Brilliant.
So, somehow you commiting assault would make you right, is that your argument?
I'm actually 183 lbs., and a member of the U.S. miliatry. I work out regularly, including weights and running. Not huge, by any means, but far from the tiny person you seem to wish I were.
In any case, that really doesn't matter. You are misunderstanding. You are wrong. Let's start formt he top, and I promise not to use big words.
There are two types of calorie, the gram-calorie and the kilogram-calorie.
When calories is used in reference to food, it refers to the kilogram-calorie. The 2000 calorie a day "average" diet is based on kilogram-calories. The calorie listings on food labels in the U.S. is based on the kilogram-calorie. All of this is based on the kilogram-calorie.
So, 500 kcals is 500 calroies, or about 1/4th of the average daily diet. You burn about 150 calories, or 150 kcals, in a half-hour or so fo running (if I remember my figures correctly). 500 kcals (or 500 calories) in an exercise session is not unreasonable.
You also missed this part of the link:
Colloquially, and in nutrition and food labelling, the term "calorie" almost always refers to the kilogram calorie. This applies only to English text; if an energy measurement is given using a unit symbol then the scientific practice prevails there.
"kcal" is the scientific unit symbol, indicating he was referring to "thousands of gram-calories" rather than "thousands of kilogram-calories". You immediately assumed (because of your ignorance) that he was talking about "thousands of kilogram-calories", because you don't know what you're talking about. You either did not know that kcal refers, specifically, to the gram-calorie, or you did not know that "calorie" as used in non-scientific areas (such as dietary amounts and food labelling) refers to the kilogram-calorie.
This is information that is covered in high-school level chemistry texts. Thus, it rather puts paid to the idea that you are an "expert" in fitness and nutrition.
Of course, despite the fact that this information has been clearly spelled out to you, provided in no uncertain terms in the links, and that basically you are the only who seems to think you are right, and the fact that you have no evidence to show that Greco's usage was incorrect, you still insist that everyone else is being childish and you are correct.
Of course, then you tell me you'd smash my teeth in because you are, apparently, too full of yourself to admit error, too happy to jumpo on others for mistakes (whether they made them or not), too insecure to think someone might tell you off unless they had a message board to hide behind, and too ignorant (I'm using the specifically correct usage of the word, mind you) to understand the issues at hand.
