Final answer:
It is false that there is nothing we can do to slow the loss of lean body mass as we age. Lifestyle changes, especially regular exercise and a healthy diet, can reduce the rate of muscle and bone loss.
Step-by-step explanation:
The statement 'As we grow older, there is nothing we can do to slow the loss of lean body mass' is false. Lean body mass, which includes muscle and bone mass can decrease with age, contributing to a slower metabolic rate and a decrease in physical strength. However, this process can be mitigated through lifestyle modifications. Maintaining a healthy diet and regular exercise can help to preserve muscle mass and bone density.
Strength training and weight-bearing exercises are particularly beneficial in slowing the loss of lean body mass. Additionally ensuring adequate protein intake is crucial for muscle maintenance. It's important to recognize that each individual can respond differently to aging based on genetic makeup and lifestyle, but overall active efforts in lifestyle management can positively impact the rate of muscle and bone loss.
