The bad news is that fat cells can increase both in size (hypertrophy) and in number (hyperplasia). But you as a human being can only increase muscle (fiber) size, but not number. That’s a disadvantage!
When you “lose” body fat, the fat cells don’t go anywhere. The fat cells stays right where they were before, under the skin and on top of the your muscles. In fact you just “empty out” or “shrink” the fat cells.
Fat is stored inside the fat cells. The fat is not burned right there in the fat cells, it must be liberated from the fat cells through somewhat complex hormonal and biochemical pathways. Fat cell releases its contents (triaglycerol) into the bloodstream as free fatty acids. They are then transported through the blood to the tissues where the energy is needed.
How Many Fat Cells Do You Have?
An infant usually has about 5 to 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.
Now here’s the ugly part. A typical overweight adult has around 75 billion fat cells. 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, ranging from 0.2 micograms to 0.9 micrograms. An overweight person’s fat cells can be up to three times larger than a person with ideal body composition.
Sounds depressing!?
What Can You Do to “Shrink” the Fat Cells for Good?
Learn the following take-home fat lessons:
- Calories count! The signal that triggers your body to release adipose from fat cells is an energy deficit… you have to burn more than you eat.
- Cut calories conservatively. Starving yourself may cause quick weightloss at first, but never works long term because it actually decreases the activity of fat burning enzymes that release fat from the cells. to avoid this “starvation mode” use exercise to BURN THE FAT, not very low calorie crash diets.
- Get control of your weight now. If you are gaining weight, and especially if your weight is climbing upwards out of control, make a decision to STOP RIGHT NOW. Your fat cells might be multiplying, making it more difficult to get lean in the future. NOW is the time!
- If you’ve already lost weight, you must be forever diligent. Your fat cells are not gone, they have merely “shrunk” or “emptied out.” Fitness is not a 12 week program, its a lifestyle. To stay lean you have to eat clean and stay active.
- Genetics are only a minor factor. You may not have control over how many fat cells you were born with, but you do control the major factors that determine how much fat you store: lifestyle, exercise, nutrition, mental attitude.
