What is meant by "changing body composition"?

[dirtyluke1]

I keep on hearing this what does it mean "changing body composition"?

 

[GoldenDelicious]

changing the proportion of bone, muscle, fat, blood, and water that make up your body

In reality, it is lowering (or raising) your BF%. This is done by either reducing absolute fat or increasing LBM (to lower BF%) or the opposite to raise BF% (gaining fat and losing LBM).

Sounds like more than it is. If you ate pizza hut and mcdonalds everyday for the next 10 weeks of your life you'd be changing your body composition too..

almost like another puberty.
