Sarcopenia and increased adipose tissue infiltration of muscle in elderly
The inflitration of fat into skeletal muscle is one of those subtle changes that occurs over time that can have a dramatic effect on long term health. Try this scenario–a young woman skips breakfast in an attempt to cut calories and lose weight. And she is successful. However, some of the weight lost has been replacement of lean muscle mass with intramuscular fat. She even looks like she lost weight. But she has made a devastating change to her biochemical makeup. The weight will come back on–with less lean muscle mass it is inevitable–and each cycle it gets harder and harder to lose the weight.
