We can change are hair, but we can’t change body mechanics.
Many Americans fight the daily struggle of loosing weight, some try fad diets, while others try workout routines. Some times they work other times they fail. With multitude of trainers and health professionals promoting the answer of how to loose weight, we get lost in where to start. I believe we need to go to the basics. We need to learn how are bodies work and what is natural to put into our bodies, so that we can reap the benefits.
Metabolism is the process of how are bodies use the energy (calories) produced by the food we consume. Many people fear calories but we forget that without them are bodies couldn’t operate. The human body needs calories to release energy into your body so that you can breathe, circulate blood, adjust hormone levels, or any other functions at rest, this is considered basal metabolic rate (BMR). Are BMR varies from age, sex, lean body mass, and levels of various hormones in the blood. Metabolism slows down as we age with a 3% decrease every decade beginning at the age of thirty. It is more likely for a man to have a higher metabolism due to higher amounts of skeletal muscle. Another variable is the amount of body surface, this has to do with how much heat is lost through the surface of your skin. Are cells are constantly active to maintain body temperature, so they have to work harder the more heat are bodies loose. BMR contributes to about 70% of the calories you burn everyday.
Total Metabolic Rate (TMR) is the total amount of energy being used by the body, this includes your BMR and whatever is needed for physical activity. Physical exercise will increase your TMR, if you contribute to vigorous exercise your TMR will stay elevated for several hours afterwards. Food intake will also increase your TMR. Why? Because your body has to work harder to absorb the nutrients in what you are ingesting.
So before you start cutting the calories, try hitting the gym to build your muscles up. The results may not happen as fast as you would like, but your body will reap the benefits in the years to come.
