What is the difference? If there is a difference, then which should I follow for my diet.


I was thinking
400g carbs =1600 Kcal
200g Protein = 800 Kcal
60 g fat =540 Kcal.

I think people tend to just say 'cals' rather than kcals, its easier to type/say.

Oh yeah, and kcal = kilocalorie = 1000 calories.
Just say cals instead of kcals.

kcals = Calories
cals = calories

It was Kcals back in the day until the dietary guidlines made it into calories to simplify it. Anything that says Kcals may as just well say cals because they are exactly the same.

it's kinda like carat and karat (for gold & diamonds).

Actually, if I remember some of my classes from last year...

Calorie = kcal
calorie = cal

The capitalization matters...but for simplicity on this board, people just say cals.

1 nutritional calorie=1 kilocalorie=1000calories

You are going to confuse the guy, I am a registered nutritionalist and the dietary guildelines specifies us to use cal in place of kcal to simplify it...so basically they can be used interchangeably.

Well here is why I ask. One Thomas Bagel has

56g carb
10g protein
2g fat

This should equal. 282 calories.
How come on the back for the bagel package it says there is 290 calories, not 282.

I know these are close, but I am just curious.

That is an interesting question...but I'm pretty sure that difference has nothing to due with cals vs kcals.

I think bradley and Shao-Lin hit the nail on the head.

There'll be something added to the bagel mixture during prep that isn't listed under protein, fat or carbohydrate.

Go back to school then... Calories = 1000 calories. calorie is the basic measure. But it is so small it is impractical to use them on labels or anything for that matter. So they instead use Calories, Capitalized. This is learned in most intro chem classes.

100% correct


kcals = Calories = 1,000
cals = calories = 1

Anyway calories are a out of date imperial measure. well to everyone out side the US anyway.

there are some nutrients that do not fall under fat, protein, carbs.

eg alcohol.

they will round the number to the nearest
whole number often.
plus they do make mistakes when doing these calculations.

plus they do not equal exactly 4kcal per gram etc. even though peeple say carbs = 4kcal. some starches have differnet levels to some sugars.

plus when they measure for fat etc. they measure the fatty acids. and work out the fat level from that. they do not meusure the fat when attached to the glycerol. for most foods it will only lead to slight inaccuracy.

plus there is slight room for inaccuracies. if you buying a product that is not making a nutritonal claim. it does not matter if they put 65 grams of carbs or 68 grams. its not much difference.
plus the food will vary with seasonal varatation, batch make up, cook time etc. to many things to be that accurate with the info.

Some companies will only use factory samples to work out nutritionals. while other will combine nutritionals with theoreticals to work out nutrionals.

I have rang some labs up and told them, they have worked out my products wrong, then they ring up a hour later and say whoops. they made a mistake.
Most people who do my job are not sad(well the rest of you as well) like me and find nutrition interesting so little mistake let this get by.
