Earlier this week someone in our discussion forum wrote, "I have not" lost "any fat ... I know where it went! I got a chuckle out because I" got "the joke, but the truth is, most people really do not know how fat cells work, how the fat burning process takes place or where the fat goes when it is burned. it is actually quite a complex biochemical sequence sequence of events, but I'll explain it as simply as possible, so by the end of this article, you are a "fat burning" expert! when you "lose" body fat, the fat cells ( also called an adipocyte) does not go anywhere or move the muscle cell to be burned.'s fat cell itself, (unfortunately) stays right where it was - under the skin on your thighs, stomach, hips, arms, etc., and on top of muscles - which is why you can not see muscle "definition" when your body fat is high. fat is stored in fat cells in the form of triaglycerol.'s fat is not burned right there in the fat cell, it must be liberated from the fat cell through somewhat complex hormonal / enzymatic pathways. when stimulated to do so, the fat cell simply releases its contents (triaglycerol) in the blood as free fatty acids (FFA's), and they are transported by the blood to the tissues where the energy is needed.
A typical boy about adult stores calories 60000-100000 energy in body fat cells. know what triggers the release of all these stored fatty acids from fat cells? simple: when your body needs energy because you're consuming fewer calories than you are burning (an energy deficit), then your body releases hormones and enzymes that signal your fat cells to release your fat reserves instead of keeping them in storage. for stored fat to be liberated from fat cell, hydrolysis (lipolysis or fat breakdown), splits the molecule of triaglycerol glycerol and three fatty acids. an important enzyme called hormone sensitive lipase (HSL) is the catalyst for the reaction. stored fat (energy) gets released blood as FFA and they are shuttled off to the muscles where the energy is needed. as blood flow increases to the active muscles, more FFA's are delivered to the muscles that need them. an important enzyme called lipoprotein lipase (LPL), then helps the FFA's get inside the mitochondria of the muscle cell, where the FFA's can be burned for energy. whether you've taken a biology class, then you probably heard of the mitochondria. has been the "cellular powerhouse" where energy production takes place and this is where the FFA's go to be burned for energy. When the FFA's are released from the fat cell, the fat cell shrinks and that The reason why you leaner when you lose body fat - because the fat cell is now smaller.
A small or "empty" fat cell is what you're after if you want the lean, defined look. has been once believed that the number of fat cells did not increase after adulthood, only the size of fat cells could increase (or decrease). know we now that fat cells can indeed increase both in size (hypertrophy) and in number (hyperplasia) and that they are more likely to increase the number of specific time and under specific circumstances, such as 1) during late childhood and early adolescence, 2) during pregnancy , and 3) During adulthood when extreme amounts of weight are gained Some people are genetically predisposed to have more fat cells than others and women have more fat cells than men.
A baby usually has about 5 - 6 billion fat cells. This number increases during early childhood and puberty, and a healthy adult with normal body composition has about 25 to 30 billion fat cells. typical hyper- in weight with adult around 75 billion fat cells. but in the case of severe obesity, this number can be as high as 250 to 300 billion! The average size (weight) of an adult fat cell is about 0.6 micrograms, but they can vary in size from 0.2 to 0.9 micrograms micograms. overweight person's fat cells can be up to three times greater than a person with ideal body composition. remember , body fat is basically just a reserve source of energy and fat cells are the like the storage tanks. unlike a tank of gas in your car which is fixed in size, however, fat cells can expand or shrink in size depending on how "filled" they are. picture of a balloon not inflated: It's tiny when not filled with air - maybe the size of your thumb. when you blow it in the air, it can expand 10 or 12 times it's normal size, because it simply fills up. what happens to fat cells:
They start nearly empty fat storage "tanks" (when you are tall), and When energy intake exceeds your needs, your fat cells "fill up" like balloons (not a pretty picture, is it?) so you actually "lose" fat cells, you "shrink" or " empty "fat cell. since fat cells can not only get bigger, but multiply as well, you should be diligent and consistent in your fat-burning lifestyle because even after you shrink your fat cells , the cells are still there (in your thighs, lower abs, etc.), waiting to be filled up with more fat again, if you're not careful ... to stay active to keep burning fat and avoid consuming more calories than you burn, and your fat cells will get shrunk and shrunk stay!
