know how walking helps preserve lean muscle

When people cut calories and lose weight, they often lose some muscle in addition to body fat. 

This can be counterproductive, as muscle is more metabolically active than fat 

This means that having more muscle helps you burn more calories each day. 

Exercise, including walking, can help counter this effect by preserving lean muscle when you lose weight. 

Preserving lean muscle helps reduce the drop in metabolic rate 

that often occurs with weight loss, making your results easier to maintain. 

What’s more, regular exercise can reduce age-related muscle loss 

helping you retain more of your muscle strength and function in later years.
