Black Coffee = Negative caloric intake

Derexan

I would assume that Black Coffee would actually be a negative caloric intake food considering that it has roughly 3 calories per 8oz, and caffiene has mild thermogenic/diuretic effects and increases your heart rate.

Are my assumptions correct?
 
Coffee also affects blood insulin, so using more is not neccessarily better. Like most things in life you play with one thing and you affect another.

No such thing as a negative calorie that I know of.
some vegetables have negative calories, meaning it takes more energy (calories) to consume and digest the food than the food contains in the first place. apparantly coffee is the same way.

That would be changing the definition of a calorie, then.

In such cases as the all-cabbage diet, the cabbage doesn't have these so-called negative calories, but the calories per unit volume is so small that even a full stomach is full of a relatively small number of calories. It is therefore difficult to get many calories in per day and the person looses weight. Thus, the reason the person lost weight is because they had an overall calorie deficit.

But who cares if something has 5 calories or -5 ? 5 calories is so meaningless.

But with the coffee, FYI that the flavored coffee tends to add more calories. This is something of note to low-carbers, in particular.

no it wouldnt

if a bowl of lettuce has 5 calories, and it takes 6 calories to chew, swallow, and digest the lettuce, thats negative calories.

if a steak has 500 calories, and it takes 6 calories to chew, swallow, and digest the lettuce, those calories would be used and/or stored by the body.

those would be 'net calories' or similar.
 
why there is no such thing as a negative calorie:
That twinkie i ate has negative calories. I walked 1/2 mile to the store, bought the twinkie. Ate it, then walked backed home. If you count the calories i burned on my brisk walk, the calories it took to chew and digest the twinkie, then thats negative calories.

It only matters how many calories you take in vs. calories burned.

you can't say. i ate 3525 calories today, but 25 of it was actually negative calories from lettuce. So i only had 3500 calories.
 
This is kind of funny. The food is going to have x amount of calories regardless of the thermic effect of the food. Just because it takes more energy to digest it doesn't effect the fact that the food still has x amount of calories in it. You can't have a negative calorie, unless you are eating black holes or something.

Thank god for some common sense
