    I always think of it kind of like my body eats it? Lol, that is no way near technical. But my body uses it up to fuel things, instead of using the tons of extra calories that I was eating before, with enough left to store for later.

    I'm sure somebody can give a more scientific answer, but the bottom line is that your body uses it for fuel and then the waste is eliminated through the digestive system. Drinking lots of water helps with this process.

    I think it becomes liquidfied and evaporates in sweat or you pee it out, like the whooish effect before a scale loss.

    If fat dissolves into the blood stream how does it get out of there?

    It isn't fat at that point - it is converted to FFA , then leaves the fat cell & goes into the blood, and then it is sent to and absorbed into muscle cells and burned there in the mitochondria. it's all in the article.

    I always wonder about this too, and no explanation has ever really cleared it up completely. There is 112 pounds of me GONE, and it seems like I should have seen it leaving!!

    Think of it as wood - you burn the huge lump of wood (fat) for energy (heat) and all that is left is a small amount of ash (which we pee out basically).

    Personally, I think it's transporter beam. I go to bed at one weight and wake up another. Without peeing in the interrum. :)

    Actually, it gets metabolized, the waste eliminated in the toilet and breathed out as vapor and exhalation. The rest broken down chemically by the body and built into other body parts.

    You might as well ask how your body built it or how wounds heal.

    Aah but it snuck out whilst you were sleeping! Fat is sneaky like that. :wink:

    This gets me too, I go to bed one weight and wake up three pounds lighter. It's like the fat fairy came and took it. Which is okay with me, just puzzling!

    well you can stay at maintainance at burn 500 cals a day n you will lose a pound every week. 2nd ques when you are burning fat look for when thing when you go to toilet to pee you will notice something white in your pee is like chicken fat thats how some of your fat comes out n some as a sweat. because when i did a diet few years back when the white thing came in pee i got scared that its something serious but found out its nothing just fat so a doctor knows best.

    Fat is a glyceride chain that stems from the fat cells. When you lose weight, your body is eating away at the ends of this chain to provide energy for your body. Think of fat cells like balloons, when you gain weight you are blowing up the balloon but its still only the one fat cell it is just growing. Fat never truly leaves us, it only grows and shrinks with your eating habits.
    Interestingly enough, when people have liposuction, some fat cells are pulled out permanently. which if you are not careful, if you gain weight its just going to look odd as to where your body stores fat.
    Interesting article!

    As heat, literally.

    Fat is being burned all the time as an energy source, majority of the time actually, along with carbs.

    Its all a matter of are you eating more than required and replenishing it, or even adding to fat stores?

    Or hopefully, it's not.

    Cell biology explanation:

    Fat (lipids) are long chains of molecules. When the chains are broken in the right place, it liberates a lot of energy. The energy is used to turn ADP + phosphate into ATP, which is what cells use for energy (breaking it back into ADP + phosphate). So, you have this broken chain of molecules which are useless to the body. The blood pulls them from the cell (through the cell wall, the same way water, glucose chains, and everything else goes into and out of the cell). The kidneys (and sometimes liver, but mostly kidneys) filter the blood, pulling the broken chains out. This is part of what is in your urine. So, you pee out the remnants of the fat.

    ETA: it's been almost 15 years since I took cell biology in college, so I'm sure I've forgotten a significant amount of the details, but I think I got the basics about right.

    When you are sleeping, the fat cells that you have p1ssed off that day pack their bags and leave, looking for someone who will feed them. If you eat too much, those wandering fat cells come to you in your sleep. They may or may not be delivered by a stork or some other wild life.
