Traditionally body builders would make every effort to minimize or completely avoid fat in their daily food intake. But that perception is changing as breaking research is finding that the right amount of dietary fat is more important that we realized.
The right fats in the right amounts are actually good for our bodies. As for the muscle men and women out there, you can stand to benefit from the extensive research that is taking place right now. How the findings apply to you is really a function of where you are in your fitness program and what your long term goals are.
