1,
Well i hear that it lowers calories, increases calories(less say this) and it only decreases the water thus increasing the calories per gram.

I use cal/g to calculate all of my calories, but if I can use the pre-cooked total that would be great.

I see:

1.1 cal/g on chicken breast and 1.65 for roast chicken breast (skin/bone-less). That is a big difference in cal/g for just water removal, like 50%

If cooking does not increase calories how come cooked food is so much tastier, is it due simply to higher cal/g (caloric density) due to water loss.
2.
With olive oil does 1mL = 1g? What about mariner, can I use grams when the serving is in mL to measure g * g/cal

_______________
3.
Somewhat dry roast beef cooked in a pressure cooker then baked, the not fatty part with all fat whatsoever that can be removed, removed.

I find nutritional information with anywhere from 1.5 cal/g to 3.0 cal/g online. Beef isn't really something I can measure before cooking even if cooking doesn't add calories, as the portion I eat isn't nearly the entire roast.

I was using 2.0 cal/g but I've increased my estimate to 2.2 cal/g... should it be higher?? should it be lower??

This is the kind of roast beef that is about 10 inches long 5 inches wide and 3 inches tall sort of oblong in shape. The meat cal be pulled apart top to bottom in sorts of strings like you could separate those stringy cheese cylinders that were popular for kids lunches.

    1. Yes, foods can lose a lot of water weight after cooking. Plus, that amount can vary depending upon many factors. That's why it's best to go off of the pre-cooked weight. Flavors condense when water is removed.

    2. No. Only water is 1ml=1g. Different liquids have different densities. A quick Google search says that olive oil can have about .8 to .92 grams per milliliter at 20 degrees Celsius.

    3. If you can't measure before cooking, all you can do is estimate as closely as you can. Even getting a raw weight isn't exact because of a varying amount of fat. Calorie counting isn't exact and all we can do is get as close as we can with our estimates.
