It's important for you to understand that our metabolism slows as we age – by as much as two percent a year!
But there is something you can do to counterbalance nature.
“Muscle is the single most important factor for how well you metabolize your food, how well you burn calories
and burn body fat.”
Metabolism is affected by your body composition. By body composition, I mean the amount of muscle you have versus the amount of fat.
Muscle uses more calories to maintain itself than fat.
People who are more muscular (have a lower percentage of body fat) they have a higher metabolism than others that are less muscular.
For example, let's say you have two people who are the exact same height and weight. One exercises on a regular basis with weights, in addition to aerobic exercise, and has a low percentage of body fat. The other never exercises and has a higher percentage of body fat. The first person who exercises will have a higher metabolism than the second person. What this basically means is that person #1's body will use more calories to sustain itself than person #2.
Strength training with dumbbells or resistance bands at least twice a week is essential to boosting your metabolism. I Repeat – essential.
Your metabolism stays pumped for many hours after you finish your workout.
When I'm out for a run or a walk I find a park bench to do push ups and triceps dips, add a few more each time to increase your strength. When your watching TV, use your chair and do the same thing!
