Is a calorie a calorie?

[Thin Lizzy]

I apologize if this point has already been made.

I remember reading that lettuce was a "negative calorie" food: meaning that it takes more calories to digest than it contains.

That said, wouldn't eating, say, 500 calories of lettuce be different than eating the same number of calories of a "positive calorie" food?

It's not as though you can skip the digestive process.

Is a frog a frog?
Is a car a car?

I'm confused by the ambiguity of your question. 
perhaps you've mispelled one of the words.  You've asked if two exact same words are the same?

it would take a shitload of lettuce for it to equal 500 calories.

Fuck, you're an idiot.

[swilkins1984]

Yes, in terms of the unit of heat energy...but not necessarily when it comes to our individual human physiological responses to them.

Exactly. Whereas it would only take about two donuts. Your body would burn way more calories digesting the 500 calories of lettuce.

It would be like saying that cardio is cardio, but ignoring that certain types of cardio burn more calories than others.

Perfect example

google "thermic effrect of food"

but yes i believe a calorie is a calorie for active people..

good luck on eating all that lettuce.   Not practical.  Plus it's only negative calories if you don't use any condiments.

WHY THE THERMIC EFFECT OF FOOD IS MEANINGLESS!!!!!!!!! for the 98435890435834 time.

Protein has a Thermic effect of about 15% wheras carbohydrates are around 10% as studies indicate.

What this represents is the calories burned through digestion.  There is not a significant variance to even matter.

Lets say one takes in 300 grams of carbs or 1200 calories.  10 percent burned is going to be 120 calories.

Now lets compare 300 grams of protein or 1200 calories.  180 calories are going to be burned in digestion.

The variance of 60 calories means nothing.  Typing on the computer for an hour also burns 60 calories.

Hope this helps you guys.

It would take about 6.5 LBS of lettuce. hahahahahahah

haha brutal water weight.   I imagine eating 1/3 of that would be challenging and painful to the stomach.

I'll stick to the 2 donuts.

and that applies to EVERY SINGLE HUMAN  BODY...

lol bullshit..

i beg to differ..

The variance will not be enough to still make any real significant difference.
