No, it doesn't.
It has to do with the structure of a fat cell compared to the structure of a muscle cell as shown here. Guess which one is the fat cell? 
If you take two identical boxes and fill one with fat cells and the other with muscle cells, the muscle cell box will weigh more. Not because muscle weighs more than fat but because more muscle cells fit in the same space.
One more word-intervals. Hill repeats, sprint repeats, or standing repeats.
