It's not 3,500kcal/pound!!!

Lift_hard_eat_big

So Pu_239 and I have been discussing, you need to burn almost 3,700 of FAT kcals to lose a pound of fat.

1 pound = 454 grams
1 gram of fat = 9 kcals
Therefore, one must burn 4,086 FAT kcals to lose a pound of fat. EDIT: Multiply by .9(correction factor) = 3,677kcal
However, our bodies constantly burn a mixture of fuel sources, i.e. carbs, fat and fat simultaneously.

Just some food for thought.

Seems like there's something you're missing.

WAT in humans is composed primarily (anywhere from 80 to 95%) of lipid. By lipid, I
mean stored triglycerides (TG) which are simply a glycerol molecule bound to three free
fatty acid (FFA) chains. The remaining part of the fat cell is comprised of a little bit of
water as well as all of the cellular machinery needed to produce the various enzymes,
proteins, and products that fat cells need to do their duty. As it’s turning out, fat cells
produce quite a bit of stuff, some good, some bad, that affects your overall metabolism.

For the record, one pound of fat is 454 grams and let’s assume 90% lipid on average. So
about 400 or so grams are actual stored TG. When burned by the body, one gram of fat
provides 9 calories so 400 grams of fat contains about 3600 calories of stored energy. Now
you know where the old axiom of ~3,500 calories to lose a pound of fat comes from.[/quot]

I believe you are confusing "Fat" as found on a Nutritional Label and "Fat" as we commonly refer to it in our bodies - e.g. non-lean tissue. These are not the same.

Oh sorry we're off by 11.89%

Which brings us down to the 3500 that you were disputing. So what was your point again?

if someone wants to tell me how many calories to be burning to lose 15lbs of fat that'd be greatt, need all the help i can get!

I think it was operator error.

...tagging this post...

just to see where it ends up.

LabRat529

It never works out exactly anyway. Weight loss isn't linear and... well... we're usually guestimating calorie burns and calorie intakes and so on and so forth, so a 3500 kcal deficit each week might make you lose 1 lb a week or it might not.

Acg, thanks for the link, that makes much more sense. But even if we assume 90% lipids on average, that's closer to 3,700kcal than 3,500kcal. So someone who only has a 400kcal daily deficit would lose weight half a quickly as planned

This thread is GREAT!

AFitJamie

if someone wants to tell me how many calories to be burning to lose 15lbs of fat that'd be greatt, need all the help i can get!

A simple answer to your question in line with this thread might be : 15Lbs X 3500 = 52,500 calories..... approximately

This is what you will need to burn off....

Now, to do so you need to establish what you should be eating each day that will slowly have you burn off a bit more each day than take in... and before you know it you will have burned off 52,500 calories. This thread isn't the place to hijack for a discussion of targets for you, but friend me if you like and I am happy to help you through the details...
