At the same time, you're building muscle in your legs, which weighs
more than fat tissue, so what the scale says isn't a great reflection of overall fat loss.
Strength training builds lean muscle mass, which increases the metabolism as muscles burn more calories at
rest than fat tissue.
The reason it does this is by increasing the amount of lean muscle mass you carry, which requires more energy to maintain and
repair than fat tissue.
Weight training stimulates metabolism, thus allows you to burn calories more quickly because you increase muscle mass, which uses a lot more
energy than fat tissue.
Muscle tissue is more
dense than fat tissue so a pound of muscle is smaller than a pound of fat — but a pound is a pound is a pound — whether it's muscle or fat or feathers.
Fat tissue taken from mice on a high - fat diet rich in omega - 3 fatty acids (right) has fewer inflammatory immune cells (shown in green)
than fat tissue taken from mice that did not receive the omega - 3 supplement (left).
Muscle tissue is more metabolically
active than fat tissue but the extra calories it takes to maintain muscle mass is nothing to write home about.
Sportsmen are heavier than people who don't do any exercise because muscles weigh
more than fat tissue.
