The more muscle we have, the faster our metabolic rate, as muscle burns calories even when we are at rest.
As we age muscle mass reduces. After the age of 40 it reduces by 8% a decade. The result is that our basic energy expenditure decreases by approximately 150 calories daily per decade. Consequently as we get older we need to eat less to stay at the same weight. Regular exercise will help counteract this. Lifting weights and body weight exercises such as squats, lunges and push ups will help maintain and build up our muscle mass and protect our bones.
