Does fat storage use energy

Options
I've googled & googled but can't find an answer on this.

I'm curious if the fat we have stored uses energy just to exist.

    Well, I'm going to take an intuitive "guess." It is fuel, but it also has weight. It also has its own support structure - connective tissue, heavier bones, etc. So in that way, yes. It's more to carry so more energy is expended in day to day movement than if there were 100 pounds less to carry.

    That makes sense.

    A larger body needs more energy - a lighter body needs less (as we lose weight our maintenance calories decrease if our activity level stays the same). So I think the answer is yes. Cmriverside mentions movement, but there's also more mass to keep at the appropriate body temperature, ensure blood flow,...

    Simple answer......... yes
    because if you weren't eating enough the stored fat you use would be used as energy to support function.

    Fat cells are metabolically active, so they burn calories. Reportedly a pound of fat burns around 2-3 calories per day at rest, a pound of muscle maybe more like 6-10 calories per day at rest. Estimates vary, but the numbers aren't mostly dramatic.

    Yes it does. It helps maintain our metabolism 24/7 and is constantly being used for variable amounts of ATP (energy). Very low percentages of body fat are not healthy. Fun fact, lauric acid found in coconut oil is mostly metabolized by the liver which then converts it to immediate energy and doesn't get stored in adipose as triglycerides like other fats.

    Uh… yeah I’ll bite 😁 So, what theoretically happens if someone were to switch all their oil consumption to coconut oil? Thanks in advance!

    A body using lots of coconut oil for energy would have less need to use other fat intake for energy, thus any fat not coconut oil would be more likely to be stored as body fat.

    No idea, but probably not advisable or possible really and suspect consuming only one type of fatty acid of any description isn't something someone would want to do, and this was just a little info about Lauric acid. Cheers

    It's not just lauric acid, IMU. It's just high in lauric acid.
    Coconut oil is composed of the fatty acids, caprylic acid C -8:0 (8%), capric acid, C-10:0,(7%), lauric acid C-12:0, (49%), myristic acid C-14:0(8%), palmitic acid C-16:0 (8%), stearic acid C-18:0 (2%), oleic acid C-18:1 (6%) and 2% of C-18:2 linoleic acid.

    But that's Ghanaian coconut oil, I guess. 😉😆

    Most of those are not essential fatty acids, IMU . . . for whatever that info is worth. 🤷‍♀️ Suspect the implication would be that getting all and only coconut oil as fat wouldn't be the greatest idea ever, but it would also be pretty hard to totally avoid fats from other sources while still eating food. 🤷‍♀️

    Wow, what an interesting article as I happen to be a Nigerian (I live in Ohio) who never stopped eating palm oil despite the bad rap it seemed to be getting. And now to find out that at least some of it was financially motivated. “No, no don’t cultivate your local crop, import ours instead” 😏
