Your metabolic rate is based on how much energy your body needs to function properly.
There are 3 factors that make up your total energy expenditure:
1. Basic Requirements
Even when your body is at rest, it requires energy to function at it best. this includes fuel for organs, breathing, blood circulation, adjusting your hormone levels, and the growing and repairing process of cells.
2. Food Digestion
Digesting, absorbing, transporting and storing the food you consume also requires energy. Your body’s energy requirement to process food stays relatively steady and doesn’t really change.
3. Physical Activity
Physical activity like walking, cleaning and taking the stairs (plus anything else that makes you get up and move), accounts for the remainder of the calories you use.
The good news is that YOU control the number of calories you burn. This also depends on the frequency, intensity, time and type of activities you do on a daily basis.
Your Weight and Your Metabolism
It may seem like common sense to think that if you’re overweight that you must have a low metabolism. The fact is that it’s very uncommon for excess weight to be related to a low metabolism. Gaining weight is more likely caused by consuming more calories than your body burns.
What Influences Your Caloric Needs?
If you and everyone else were physically and physiologically identical, it would be simple to get your energy needs. However, there are many elements that influences your specific caloric needs.
Body Size and Composition
To function correctly, a bigger person will need more energy (calories) than a smaller person. In addition, muscle burns more calories than fat does. So the more muscle you have compared to fat, the higher your metabolic rate will be.
As you get older, the amount of muscle in your body usually decreases and your weight is made up of mainly fat. Your metabolism will also slow down naturally as you age.
Men typically have less body fat and more lean muscle than women of the same weight and age. This is the reason why men generally have a higher metabolism and burn more calories than women.
The Bottom Line
If you can increase your daily exercise and activity to build lean muscle you will burn more calories – there’s no doubt about it.
Regular aerobic exercise and resistance training will help counteract the aging process and help you maintain the amount of muscle in your body. Not only will it keep your metabolism super-charged but it will also help you manage your weight.
Look for different ways to add activity and exercise into your lifestyle. Be creative with it and in no time you’ll find simple and effective ways to burn more calories.
