The Average Adult Can Have 25-75 Billion Fat Cells
There are trillions of cells in the human body. And of those trillions, there are sometimes as many as 75 billion fat cells in the human body. This number is obviously larger or smaller depending on if you are a healthy weight, overweight, or underweight. But, the average adult typically has 25 billion fat cells if they don’t have much fat on their body and an overweight adult may have as many as 75 billion. For perspective, if you were to stack just one billion pieces of paper, it would be over 83 feet tall. That means if your fat cells were to miraculously become the thickness of paper and stacked, it would be more than 2,500 feet high — nearly half a mile!
