As we age our metabolism slows down. But can this process be changed?
"Metabolic rate is the number of calories our body requires to keep going."
When measuring our Basal metabolic rate (BMR) - the energy your body requires at rest, scientists found that it decreases with age and with loss of muscle.
As you can see by this Wiki entry the metabolism system in the body is a very complex process. (Remember the Krebs’s cycle?)
Two facts about slowing metabolism are clear.
- Many older people are less active. When people retire – they begin a more a sedentary lifestyle.
- It appears older people eat less - hard to believe but true. "When younger men and older men were doing the same amount of exercise and eating the same amount of calories, the basal metabolic rate remained unaltered.”
- Keep active - forever!
- Build muscle as it requires more energy to maintain. Try adding some kettlebell swings which workout those big core muscles.
- Don’t skip breakfast - Ever! "Your metabolism slows while you sleep, and it doesn't rev back up until you eat again."
- Get enough sleep.
- And keep on running!
What’s your BMR? ( I need around 2000 calories a day!)
