One kilogram of fat occupies 1,111 ml, which is about 23% larger than 1 kg of water. This means 1 kg of fat is slightly larger than a liter of water.
Remember, 1 kg of muscle occupies 900 ml, making fat less dense than muscle. This difference in density explains why someone with a higher body fat percentage can appear larger than someone with a lower body fat percentage even if they weigh the same.
- Practical Example: Imagine a 1-liter water bottle. A 1 kg fat mass would be slightly larger than that bottle.
- Visual Comparison: A common analogy is that 1 kg of fat looks like a wobbly bowl of jelly, while 1 kg of muscle looks like a baseball.
It's important to remember that these are just average values. The size of 1 kg of fat can vary depending on factors such as individual body composition and fat distribution.
