3500 cals = 1lb?

John said:

If 1 lb = 453.5924 g, and 1 g of fat = 9 calories, then how does 3500
calories = 1 lb of fat?

I come up with 1 lb of fat = 4082.3316 calories.

Now, if a troy pound were used, then it would be 373.2417 grams, which would
equal 3359.1753 calories. This makes more sense, but why would a troy pound
be used to measure tissue? The troy pound, or ounce per se, is obsolete,
except when measuring precious metals.

This is because animal "fat" as on an animal is really a mix of
different nutrients. I'll use butter as an example and compare it to
pure olive oil. These numbers are from
http://www.nal.usda.gov/fnic/foodcomp/search/

All are in grams per 454(lb)

P.S.:

As I remember, oils have about 8.81 kkals/gram, carbs and protein are
both about 8.85 kkals/gram. But these numbers are averages, others
will vary a little depending on individual measurements.

I'm sure there are "theoretically" correct amounts of these energies,
that all meaurements and estimates should be close to. Anybody?

The sizzle in bacon comes from its water.

Take and weigh some bacon that's low in meat, leave it exposed at low or no
heat to expel the water through evaporation, and reweigh it. That should
indicate an estimate of its water content. Human fat is probably similar
enough to some fatty bacon or salt pork.
