Would one calorie worth of alcohol, be the same as one calorie of chocolate cake? If I was watching the calories would I be better with one, the other or does it not matter?

Good question - I've heard people talking of "empty calories", but I've no idea about what is meant by this....

calories without any real nutritional value.. high in sugar fat oils, fried chicken etc. fried anything really, Alcohols turn to fat and are also empty calories...ect... If they contain no real micro nutrients like whole grains..fruits vegetables ...proteins fibers...etc they are considered empty calories!

If I were to consume 1600 calories of alcohol, apart from being as a newt, would it have the same effect as 1600 calories of cake in so far as energy is concerned?
If brains were made of dynamite, I wouldn't have enough to blow my nose.

You can analyze it this way:  Is one pound of feathers heavier or lighter than one pound of metal?  Things to think about.

Not all the calories in food can be utilised ...

Quote
Each food item has a specific metabolizable energy intake (MEI). Normally this value is obtained by multiplying the total amount of energy contained in a food item by 85%, which is the typical amount of energy actually obtained by a human after the digestive processes have been completed.

The 85% figure is an estimate as it will vary with food type.
