An athlete consumes large amounts of meat in an effort to build extra muscle tissue. Identify the correct statement about the effect of excess consumption of meat. The body utilizes excess amino acids, leading to rapid muscle growth. The body starts to dismantle its tissue proteins. The excess protein causes muscle breakdown rather than building muscle tissue. A diet high in protein does not provide sufficient energy required to support muscle growth. The body utilizes excess amino acids as fuel or stores them as fat.

The body utilizes excess amino acids as fuel or stores them as fat.
